     FIELD OF THE INVENTION 
     The present invention relates to an acoustical workspace module for improving privacy and employee production. 
     BACKGROUND OF THE INVENTION 
     In the United States and abroad, many companies employ an open office design. In addition to optimizing office space, this design was intended to foster teamwork between employees. However, this design has led to the rise of a layout which is derisively known as a “cubicle farm.” Cubicle farms are often seen as a symbol for the monotony of corporate life and are often used in movies and television as a plot device for a main character wherein they must escape their mundane life, epitomized by their job at a corporate cubicle farm. 
     Perhaps more importantly to a company, cubicle farms lower productivity in the workplace and have a negative impact on employees, affecting everything from personal privacy to health. Studies have shown, for example, that conversations between employees in a cubicle farm can lead to a 5 to 10 percent decline in performance by employees not involved in the conversations. Similarly, global studies show that, on average, people sit an average of 7.7 hours per day, with some people sitting as much as 15 hours a day. As a result of all this sitting, scientists have coined the term “sitting disease” which can cause obesity, high blood pressure, diabetes, cancer, depression, and various other maladies. While many attempts have been made to remedy these problems, the modern office environment has remained relatively unchanged. 
     One such change to the modern office environment is the move from cubicles to “desking.” Desking is the concept of replacing cubicles and cubicle walls with freestanding desks, often with desk mounted screens of various materials which provide a limited “fence” around an individual&#39;s workspace. However, while desking may do away with the perception of a “cubicle farm,” it fails to address the present privacy and health concerns present in the modern office environment. Furthermore, desking does not prevent the so-called “prairie dog effect,” in which some employees are standing while others are sitting, further reducing privacy among employees. 
     To remedy the health problems with excessive sitting, one obvious solution has been to increase standing during the workday. Studies have shown that even just taking breaks during periods of prolonged sitting may lower the health risks of sitting. Several patents have been pursued which attempt to utilize the health benefit of intermittent standing. 
     U.S. Pat. No. 9,003,979 shows one example of a stand-alone standing desk and is hereby incorporated by reference in its entirety. The &#39;979 patent provides a desk which may be utilized in the standing position to reduce some of the common side effects with prolonged sitting. However, the desk of the &#39;979 patent only allows for working in a standing position, which may not be practical for all employees, as it could lead to joint compression, muscle fatigue, and various other health problems. Additionally, the use of a standing desk in a typical open office environment may not be optimal as it would require the purchase of new desks for employees and lead to the above-mentioned “prairie dog effect.” Furthermore, the above standing desk fails to create a workstation which is ergonomically appropriate for more than a single individual. Standing for a 5 th  percentile female user differs completely from standing for a 95 th  percentile male. Accordingly, the above standing desk fails to provide an ergonomic solution for the modern office environment. 
     Another attempt to address the stand-sit balance are adjustable support structures which do not require the purchase of an entirely new desk for an employee, as exemplified by U.S. Pat. No. 6,076,785, hereby incorporated by reference in its entirety. The &#39;785 patent provides an adjustable support structure which may be mounted on an existing desk and allows employees to sit and stand at their discretion. However, these desks still do not address the “prairie dog effect” problem, and further, these support arm structures are often only able to carry a certain amount of weight. Thus, if an employee is utilizing dual monitors or various other features, the arm may not be able to remain in the standing position. Furthermore, typical non-adjustable desks such as the above stand at approximately 28″-29″ which is the seated height for a male in the 95 th  percentile. Accordingly, anyone smaller than a male in the 95 th  percentile will find it impossible to achieve a proper seated position according to ANSI/HFES100-2007. 
     Similarly, there have been many attempts to remedy the privacy concerns of the open office design. U.S. Pat. No. 7,377,078 is representative of this effort and is hereby incorporated by reference in its entirety. The &#39;078 patent discloses an integrated and adjustable privacy enclosure for workspace environments. However, the invention disclosed does not differ greatly in terms of privacy considerations from the typical cubicle walls commonly employed. Additionally, utilizing the privacy wall structures in conjunction with standing or sit-stand desks completely negates the added privacy as employees would be able to see over the privacy barriers. 
     Other attempts to remedy privacy concerns involve the use of partial visual shields, as exemplified in U.S. Pat. No. 8,845,016. The &#39;016 patent relates to mountable visual and/or acoustic privacy features which at least dampen the audio and visual pollution a user receives. However, the device presented in the &#39;016 uses shades or panels that can only be used to block out audio/visual from the sides or audio/visual from the front. However, when used on the sides, a user is completely exposed from the front and back. Similarly, when used in front of the user, they are susceptible to noise and visual pollution from both sides and the back. 
     To provide complete privacy, completely self-contained modules have been suggested, a representative example of which is described in U.S. Pat. No. 6,248,014, which is hereby incorporated by reference in entirety. The &#39;014 patent describes a self-contained activity module, which includes a work desk and chair enclosed in a housing, but open on both sides. However, while this design incorporates several features to improve the comfort of the user, it is still susceptible to audio and visual pollution from the sides. Perhaps more importantly, this design is not practical in an open office environment. The bulky nature of the design would make for an inefficient use of office space, and the cost per employee would be high. 
     Thus, there is a need for a desk which provides privacy to the user in both a sitting and standing position as well as to the other employees in the office, and which is designed to be used in an open office environment without compromising the efficient use of office space. Other problems in the field which need addressing include cabling concerns; lack of personalized lighting, air flow, and temperature controls; no individual customization; environmental considerations including improving employee attitude, creating fun and exciting work environments, and reducing stress. 
     SUMMARY OF THE INVENTION 
     Consistent with the above-mentioned needs, the present invention provides an adjustable height workstation having a selectively removable/collapsible acoustical dome for providing privacy to both the user and the surrounding users. Additionally, the present invention aims to provide a complete health and fitness environment for the user to improve work productivity and reduce work-related illnesses. 
     It is an object of the present invention to provide a desk in which the height can be adjusted. To accomplish this, the desk is designed such that it meets or exceeds the five elements proscribed in the current National Ergonomic Standard ANSI/HFES100-2007 for the 5 th  percentile seated female to the 95 th  percentile standing male user. These elements include keyboard height, wrist angle, monitor view angles, primary reach zone, foot and leg clearances, and focal depth requirements. In a preferred embodiment, the height adjustment is accomplished using telescopic legs, which may either be adjusted manually or by automated means known in the art. While the use of telescopic legs is envisioned, one skilled in the art will recognize that any adjustable height means may be utilized with the present invention. 
     It is another object of the present invention to provide a means for managing a plurality of accessories and cords. To accomplish this, there is provided a cable management raceway. In a preferred embodiment, this raceway may house a modular third party vendor&#39;s multiple circuit electrical distribution system as well as additional optional components such as ventilation fans, speakers, USB charging ports, rheostats for dimming integral LED lights, adjusting fan speed, motor control for the adjustable height table, along with any additional accessories deemed necessary by the user. The raceway serves to eliminate the common problem of a “rat&#39;s nest” of cabling found in most computer intensive workplace environments through an easy to access “cable dump” channel. The “cable dump” channel further employs a “no tools” cap which can simply be lifted off the top of the raceway for access to plug in a component or to simply hide or conceal excess cabling. 
     It is yet another object of the present invention to provide increased acoustical and visual privacy to a user. This is accomplished using a selectively removable acoustical dome or privacy shield. In a preferred embodiment, the dome is a geodesic dome based on the concept first introduced by R. Buckminster Fuller (although one of skill in the art will appreciate a vast variety of shapes for such enclosure, including but not limited to polygonal tiles, ovals, or curved pieces). The dome can be made in a variety of sizes and out of a variety of materials based on the needs of the user. In this regard, U.S. Patent Publication No. 2015/0016651 to Domash is incorporated herein by this reference, demonstrating the variety of visual/acoustic privacy features that may be desired. The dome acts to block the view from individual workstations and eliminates the potential for a “prairie dog effect” when some users are seated and others are standing. In addition, the interior surface of the dome may be modified to provide unique interfaces to the users or to incorporate features for the benefit of an employer. 
     In one embodiment, the acoustical dome is comprised of a plurality of triangular pieces which are selectively interconnected to one another to create the acoustical dome. In addition, the triangular pieces are interchangeable, which allows for user customization, in terms of transparency, color, or acoustical and light transmittance characteristics. The triangular pieces can be a variety of sizes depending on the needs of the user. In another embodiment, the pieces are pentagonal, hexagonal, heptagonal, or any other geometric shape. Additionally, the acoustical dome may be created by a combination of two or more geometric pieces. 
     In one embodiment, the geometric pieces are made of fiberglass. However, one skilled in the art will recognize that the pieces may be made of plastic, glass, metal, wood, polymers, carbon fiber, or other building materials. Additionally, the pieces can be composed of multiple materials. In other embodiments, the dome may be pre-constructed and sized to fit in a groove on the desk surface. For example, there may be an outer metal rim surrounding glass, creating a modern aesthetic similar to that present in the Louvre glass pyramid. Furthermore, the pieces can be made from a variety of electrically conductive materials or computerized screens which may provide digital environments to the user or may allow a user to “frost” the glass of their acoustical dome for added privacy. Other materials which may also be employed as geometric pieces in the acoustical dome, selected for one or more of the characteristics set forth below: weight, color, transparency, sound absorption qualities, digitization, or structural properties. 
     Once the dome is assembled, the outer appearance can vary greatly depending on the desire of the user or employer. For example, the dome may be transparent or opaque based on the materials used. However, a user may further customize the outer appearance of the dome. For example, the dome may be painted or have a print on it. For example, the outer surface of the dome may provide a tree pattern, which, in conjunction with other acoustical domes may give the impression of a desired visual depiction, e.g. a coast, a beach, a forest, a jungle, etc. In addition, the outer surface of the dome may be a variety of colors, patterns, moving patterns, light arrays, or may even change colors or themes in a rotation. 
     Similarly, the interior surface of the acoustical dome can also vary greatly. For example, depending on the materials used, the interior surface may be suitable for a digital projection of a beach or other relaxing environment to boost user productivity. It may thus be varied to the desires of a user to customize a personal working environment to avoid claustrophobia issues, to vary a worker&#39;s attitude or alertness, to conform to other environmental modifications, such as sounds (e.g. waves or a beach to coincide with the interior depiction of a sea shore; wind sounds to coincide with fanned air; a moving visual depiction such as a looped reel of a ½ hour video of a deserted beach with moving waves, trees, etc.) The interior surface can also be any number of colors, patterns, moving patterns, light arrays, or any combination of these. The interior surface is envisioned to be completely customizable for the user or employer. 
     While the above describes the shell as an acoustical dome, one skilled in the art will recognize that the shell may be a variety of geometric shapes including a cube, a pyramid, an ellipse, or a custom shape selected by the employer and unique to that work environment. 
     It is another object of the present invention to provide a spacious user workspace. In a preferred embodiment, this is accomplished through a 60″ diameter work surface which incorporates a user cutout designed to move the user into the acoustical dome for maximum acoustical effect while maintaining efficient workstation density. In one embodiment of the present invention, the workspace is provided with anti-microbial laminates for killing or resisting the presence of germs on the work surface. This anti-microbial laminate, in conjunction with a UV-C air purifier, works to reduce a high percentage of both surface and airborne germs, lessening the spread of sickness at work, reducing the number of sick days, and therefore increasing productivity and health in the workplace. Various standard anti-microbial laminate may be employed, for example, one such anti-microbial laminate includes Sharklet™ technology, described in U.S. Pat. No. 7,143,709 and hereby incorporated by reference in its entirety, may be employed to improve the anti-microbial properties of the workstation. 
     It is another object of the present invention to allow for novel and unique workstation layout designs in an open office space. This is accomplished in part using the above-mentioned cabling/electronic connector raceway. In a preferred embodiment, the raceway further includes access holes routed through the work surface, at the bottom of the raceway and concealed from view, preferably located at a specified angle of 30° to enable the creation of multiple layouts. The raceway holes located at 30° intervals also provide an entry point for the various cables emanating from the back of the CPU which is hung under the “wing” of the table on either the right or left side of the user. These cables could be USB to control both the keyboard and the mouse, the power cord for the CPU itself, headset or speaker jacks, network cables, and monitor cables. This provides an extremely neat and organized cable array on the back of the CPU—excess cable is stored in the above surface raceway hidden from view, yet easily accessible for service. Additionally, this design also allows for achieving a maximum density of users without compromising ergonomics, acoustical performance, or other features provided for in the design. The raceway can further include a fully integrated commercially available multiple circuit electrical distribution system which further prevents the creation of a “rats&#39; nest” from excess cords and cabling. In yet another embodiment, the raceway can further include a built-in air purifier, USB ports, electrical outlets, lights, speakers, webcams, or a variety of features deemed beneficial by the user or employer. 
     In one embodiment, the workstations are isolated from one another, further improving the acoustical and visual privacy. In another embodiment, the workstations are placed in “clusters” wherein two or more workstations are interconnected. In preferred embodiments, the workstations are all selectively connectable via the raceway, which allows for cords to travel from one workstation to another in a predetermined configuration designed to maximize the efficient use of space, cords, etc. In one embodiment, the workstations are connected in a zig-zag fashion incorporating as many workstations as is necessary to fill the workspace. In another embodiment, the workstations are clustered in groups of four, and placed in an efficient packing design throughout the open workspace. In yet another embodiment, the workstations are clustered in varying sizes and oriented in various directions to create an aesthetically pleasing workspace. In another embodiment, the workstations are clustered in an offset layout which helps to reduce visual distractions and enables users to be more productive. In yet another embodiment, the workstations can be placed in a geometric layout. For example, the workstations may be placed in concentric circles, further improving the aesthetics of the office. 
     In addition, the aesthetics of the workspace are further improved by the varying heights of the desks in combination with the acoustical domes. The presence of some desks in a standing position while others are in a seated position creates a unique “treetop” effect wherein the acoustical domes are all at different heights, giving the impression of looking out at trees of different heights. The “treetop” effect can be even more effective when the acoustical dome exterior is chosen with a jungle or forest pattern. In combination with the varying heights of the desks, the office may take on an urban jungle feel. Another example is a “skyscraper” effect in which the shell is a cube shape with an exterior pattern resembling a variety of buildings. When placed in an open work environment at different heights, this may create a cityscape or skyline effect. 
     It is yet another object of the present invention to allow the desk to be compatible with the “I-Fit” software control concept, described in U.S. Patent Publication No. 2010/0198374, herein incorporated by reference in its entirety. The I-Fit software allows for automated user ergonomic adjustments and individual usage history. In a preferred embodiment, users are enabled to set timers to remind them to change their working position regularly to avoid the negative effects of sitting or standing all day while working. In another embodiment, the I-Fit software can be integrated with a treadmill desk, a bicycle desk, or other exercise equipment to maintain or achieve fitness levels while working. 
     Additionally, the I-Fit software can track one or more fitness metrics including but not limited to calories burned, distance traveled, pace, time, etc. In one embodiment, one workstation including a treadmill or bike would be included in a cluster of several workstations, allowing individuals, in conjunction with the I-Fit software, to rotate through the treadmill or bike station as it is available. The I-Fit software would keep track of each individual&#39;s history of seated versus standing work as well as treadmill data includes miles, calories burned, etc., regardless of which workstation was used. The software could also exchange data through a “Bluetooth” connection or other electronic means and automatically synchronize with “smart watches” and other personal fitness monitors to provide a complete and comprehensive record of an individual&#39;s complete physical activity both at work and in time away from work. For example, in one embodiment devices described in U.S. Patent Publication No. 2012/0165633 and U.S. Patent Publication No. 2015/0230761, herein incorporated by reference in their entirety, could be utilized as a component of the fitness goals of the workstation. 
     The primary benefit and concept of the I-Fit software is to enable a proactive ergonomics program in which each user can occupy any workstation on the network and through the use of an RFID card, a fingerprint identifier, or the simple act of logging in to the network that individual is identified and their optimal working postures in either sitting or standing is automatically achieved by simply clicking and holding on an on-screen icon until the predetermined adjustment is reached. Additionally, the user&#39;s history is maintained, and management can “coach” individuals into a more healthful working routine. Additionally, a health coach could be hired to counsel and train users on the benefits associated with postural rotation (sitting and standing intervals), use of the treadmill/bike, and review each individual&#39;s fitness quotient.

     DETAILED DESCRIPTION OF THE INVENTION 
       FIG.  1    shows a perspective view of an embodiment of the acoustical dome workstation  1 . Specifically,  FIG.  1    shows the acoustical dome workstation  1  comprising a base  2 , a body  3 , and an acoustical dome  4 . The base  2  is interconnected to a bottom surface of the body  3  such that the body  3  is level to provide an optimal working environment for a user. The body  3  further includes a level work surface  31 , a “modesty skirt”  32 , and a raceway  33 . The raceway  33  further includes a track  34  which is adapted to selectively interconnect with the acoustical dome  4 . The acoustical dome  4  is comprised of a plurality of geometric pieces  41  which selectively interconnect to form the acoustical dome  4 . While  FIG.  1    shows only the structural frame of the dome  4 , one having skilled in the art will recognize that the geometric pieces  41  utilized are not necessarily limited to frame elements. Rather, the geometric pieces  41  can be solid panel-like pieces constructed from a variety of materials, discussed in greater detail in the subsequent disclosure. 
       FIG.  2    depicts the workstation  1  of  FIG.  1    without the acoustical dome. As shown, the base  2  includes two telescopic legs  21  each further having a support structure  22 . However, one skilled in the art would recognize that various base  2  structures may be used, including non-telescopic legs of various heights, a various number of legs, legs of various widths including legs which also serve as drawers, and wall-like legs. The base  2  and body  3  may be part of one integral workstation  1 , or the base  2  and body  3  may be selectively connectable for easy transportation. 
     The workstation  1  may further include a modesty skirt  32  which is connected to the perimeter of the body  3  and extends around the perimeter of the body  3 . One skilled in the art will appreciate that the modesty skirt  32  may be of various lengths and does not necessarily have to extend around the entire perimeter of the body  3 . The modesty skirt  32  may be comprised of a plurality of materials including but not limited to various plastics, fabrics, polymers, metals, cardboard, or other materials which provide privacy for the user. The modesty skirt  32  may be transparent, opaque, or may be designed such that the transparency may be chosen by the user. The height of the modesty skirt  32  may be varied depending on the needs of the user and based on the position of the workstation  1  relative to other workstations. Additionally, the modesty skirt  32  may be selectively removable or collapsible such that a user may remove it if the modesty skirt  32  is not necessary. 
     The body  3  of the workstation  1  further includes a work surface  31 . In a preferred embodiment, the work surface  31  is circular in shape having a 60″ diameter work surface  31 . However, one skilled in the art would recognize that the shape and the diameter of the work surface  31  may be adjusted based on the needs of the user. For example, smaller work surfaces  31  may be employed for children or for small working spaces, while larger work surfaces  31  may be employed for high volume workers who require a higher surface area work surface  31  or for large open working spaces. Additionally, the work surface  31  may be a variety of shapes including rectangular, triangular, elliptical, etc. The work surface  31  may be constructed of a variety of materials, including but not limited to plastic, metal, wood, polymer, and carbon fiber and may further include a laminate surface. In a preferred embodiment, this laminate surface may be an anti-microbial laminate. One such anti-microbial laminate includes Sharklet™ technology, described in U.S. Pat. No. 7,143,709 and hereby incorporated by reference in its entirety, may be employed to improve the anti-microbial properties of the workstation. However, one skilled in the art will recognize that any anti-microbial laminate may be utilized. In a preferred embodiment, the circular work surface  31  may include a user cutout  35 . This cutout  35  allows the user to move into or under the acoustical dome  4  for maximum acoustical effect and maximum privacy while maintaining efficient density. In a preferred embodiment, the cutout  35  is semi-circular in shape. However, one having skill in the art will recognize that the cutout  35  may be a variety of shapes including circular, rectangular, triangular, elliptical, etc. and may optionally be of the same shape as the work surface  31 . 
     The body  3  of the workstation  1  further includes a raceway  33  which rests on the work surface  31 . In a preferred embodiment, the raceway  33  may have multiple uses. First, the raceway  33  may act as an electrical distribution system and house a concealed 8 or 10 wire multiple circuit electrical distribution system. The raceway  33  includes cutouts at 30° intervals under the raceway to accommodate electrical/data and allow for various layout capabilities simply by rotating the workstation  1 . These features will be discussed in greater detail in  FIGS.  6 - 8   . 
     The raceway  33  may further act as a cable dump for excess cable which permits a clean and organized work surface  31  using standard length cables, eliminating the need for cable management accessories. Additionally, the raceway  33  may permit the use of regular 6 outlet power strips which may plug into the pre-engineered power distribution system and be used to power up a CPU, monitor(s), lighting including LEDs, fans, and various other accessories a user may deem necessary. The raceway  33  may further include one or more built in accessories  36 . The accessories may include fans, USB chargers, standard outlets, lighting, air purification systems, and any other accessories a user deems necessary. In a preferred embodiment, the air purification system is a UVC light/fan type air purifier which can kill and minimize airborne germs. However, one skilled in the art will recognize that any air purification system may be utilized. 
     The raceway  33  may further include a track  34  which extends a discrete distance into the raceway  33  and is adapted to receive an acoustical dome  4 . The track  34  may be of a various shapes and depths, depending on the needs of the user. In a preferred embodiment, the track  34  is adapted to receive a geodesic acoustical dome  4  as show in  FIG.  1   . However, one skilled in the art will recognize that the track  34  shape and depth may be altered to accommodate a different acoustical dome  4  shape and structure. 
       FIG.  3    shows how the workstation  1  of  FIG.  2    could be utilized in one embodiment. In a preferred embodiment, the workstation  1  utilizes three monitors  37   a,    37   b,    37   c,  arranged side-by-side, which may be mounted to the work surface  31 . However, one skilled in the art would recognize that the number and arrangement of monitors  37  utilized may be altered based on the needs of the user. By way of example and without intending to limit the scope of the present disclosure, a user may utilize one, two, three, or four monitors  37  in a side-by-side arrangement, and may further include a fifth, sixth, seventh, and eighth monitors  37  arranged in a side-by-side arranged but stacked on top of first four monitors. Alternatively, the user may utilize a variety of other monitor  37  arrangement including a diamond shape, triangular shape, or rectangular shape arrangement. Further, the monitors  37  may be the same size, or could also be a combination of different size monitors  37 . This customization allows the user to choose the monitors  37  and arrangement which meets the needs of the work for which they are being used. Additionally, while the monitors  37  may be mounted to the work surface  31 , one skilled in the art will recognize they may also be mounted to the raceway  33  or may be freestanding. In a preferred embodiment, a fixed version of device found in U.S. Pat. No. 8,596,599, herein incorporated by reference, is utilized, allowing limited horizontal and vertical adjustment while using less space than a monitor arm and other traditional means of monitor mounting. In addition, while not shown in  FIG.  3   , the monitors  37  may also be integrated into the acoustical dome  4 .  FIG.  3    further illustrates other accessories which may be utilized with the expansive work surface  31 . By way of example, the accessories may include a telephone, a keyboard, a mouse, speakers, utensil holder, file tray, stapler, hole punch, or any other accessory deemed necessary by the user. Additional optional components may be included, such as ventilation fans  6 , speakers, USB charging ports, rheostats for dimming integral LED lights, adjusting fan speed, motor control for the adjustable height table, along with any additional accessories deemed necessary by the user. 
       FIG.  4    depicts one embodiment of the workstation  1  in which the height of the workstation  1  is adjustable.  FIG.  4    shows the workstation  1  in three different height positions: a minimum height  1   a,  a medium height  1   b,  and a maximum height  1   c.  However, one skilled in the art will recognize that the various heights  1   a,    1   b,    1   c  are only representative, and that the actual height of the workstation  1  may be any height between a minimum height  1   a  (5 th  percentile seated female) and a maximum height  1   c  (95 th  percentile standing male user). In a preferred embodiment, the workstation  1  is adapted to comply with the five requirements of ANSI/HFES100-2007 National Ergonomic Standard for computer workstations such that it enables individualized fit for all potential users from the 5 th  percentile seated female user up to the 95 th  percentile standing male user. The five requirements are keyboard height/elbow angle, monitor height/view angle, focal depth, primary reach zone, and user safety clearances. These ergonomic considerations allow the user to avoid the negative health consequences of sitting or standing all day, while achieving a customized ergonomic fit for their individual physical attributes. 
       FIG.  4    further shows one embodiment of the acoustical dome  4 . As shown, the acoustical dome  4  shields the user from other users who may be located adjacent to the workstation  1 . The acoustical dome  4  is constructed from selectively interconnecting geometric pieces. In the embodiment illustrated in  FIG.  4   , the pieces are triangular. However, one skilled in the art will recognize that the pieces may be pentagonal, hexagonal, heptagonal, or any other geometric shape. Additionally, the acoustical dome may be created by a combination of two or more geometric pieces with a different geometric shape. Similarly, while an acoustical dome is a preferred embodiment of the present invention, one having skill in the art will recognize that the acoustical privacy shield  4  may be a cube, pyramid, cone, ellipse, or other shape based on the needs of the user. As shown, the dome  4  is connected to the body  3  via the track in the raceway  33  and extends above and behind the user to improve privacy. 
     In another embodiment, the monitors may be integrated into the acoustical dome  4 . This can be done either by utilizing electronically interconnected geometric pieces which allow the geometric pieces to act as the monitors. Alternatively, the monitors may be built into the acoustical dome  4  design and surrounded by geometric pieces. 
     In embodiments, the workstation  1  and/or the acoustical dome  4  may include lighting elements, and in particular may include one or more light-emitting diodes (LEDs) or strips or banks thereof, which may be affixed to any suitable portion of a work surface  31  and/or an inward-facing (work surface-facing) surface of the acoustical dome  4 . It may be particularly preferable for lighting included on the work surface  31  and/or the acoustical dome  4  to be controllable by a user of the workstation  1 , e.g. to allow a user to brighten, dim, and/or change the color of the LEDs or other lights. In this way, the user of an individual workstation  1  may be able to illuminate the workstation  1  to his or her individual preferences, which (in environments where a plurality of workstations  1 , each having a separate user, is provided) may allow for a decrease in the amount of ambient light, e.g. to the degree needed to provide safe egress from the environment in an emergency. Thus, providing each workstation  1  with lighting controllable by the user of the workstation  1  may result in an overall reduction in electrical usage, thus providing an important advantage and benefit relative to the prior art. 
       FIG.  5    shows one embodiment of the geometric pieces  41  which make up the acoustical dome  4 . Shown are component geometric pieces  41  from an embodiment in which the acoustical dome  4  is a geodesic dome comprising selectively interconnecting triangular geometric pieces  41 . Two embodiments of the geometric pieces  41  necessary for construction of the dome  4  are shown. Eight large geometric pieces  41   a  and twenty small geometric pieces  41   b  are utilized to create the geodesic dome  4 . In a preferred embodiment, the large geometric piece  41   a  is an equilateral triangle having a side length of 17.92 inches. Alternatively, the small geometric piece  41   b  is an isosceles triangle having a side length of 15.85 inches and a base length of 17.92 inches, wherein the angles between the base and the sides are both 55.57° and the angle between the two sides is 68.86°. While large  41   a  and small  41   b  geometric pieces are shown, one having skill in the art will recognize that the pieces may be a variety of sizes to either increase the number of pieces  41  or decrease the number of pieces  41  used in the dome  4 . 
       FIG.  6    depicts a novel workstation  1  layout for an open workspace environment utilizing the present invention. In a preferred embodiment, the workstations  1  may be arranged in a zigzag or offsetting arrangement. This arrangement allows for an efficient use of workspace in order to maximize the density of users without degrading the privacy of the users. Moreover, as will be shown in greater detail in  FIGS.  7 - 8   , this arrangement utilizes the raceway of each workstation  1  to interconnect the units and cut down on “pile-up” of electrical cords. This arrangement also provides a unique office aesthetic when the workstations are positioned at different heights. This customization allows both the users and employers to fully optimize their work environments. 
       FIG.  7    shows a plurality of alternative workstation  1  layouts and the electrical distribution pathways utilized to connect the workstations  1 . These layouts may be described as zigzag opposing  71 , zigzag offset  72 , square  73 , diamond  74 , and oval  75 . In a preferred embodiment, the zig-zag layouts  71 ,  72  are utilized. As shown, in each of the layouts  71 , 72 , 73 , 74 , 75  the electrical distribution pathway  76  is shown connecting the plurality of workstations  1 . In a preferred embodiment, the electrical distribution pathway  76  makes a connection with each workstation no matter which layout  71 , 72 , 73 , 74 , 75  is utilized. However, one skilled in the art will recognize that a user may create unique layouts by utilizing two or more electrical distribution pathways  76  in one layout. 
       FIG.  8    provides a more detailed look at the raceway  33  which allows for the unique layouts described in  FIG.  6   . Shown are two workstations  1  connected via an electrical distribution pathway  76 . As shown, the pathway  76  travels through the raceway  33  of each workstation  1  wherein the pathway  76  connects to an electrical outlet  77  before continuing to the next workstation  1 . The electrical outlets  77  comprise two connectors  78 , 79  on each end which connect to the pathway  76  and allow it to continue to the next workstation  1 . The pathway  76  continues until it reaches the last workstation  1  in the chosen layout. 
       FIGS.  9   a  and  9   b    show one embodiment of the geometric pieces  41  shown in  FIG.  5   . More specifically,  FIG.  9   a    shows the two component pieces, before assembly, which may make up the geometric piece  41 : the geometric frame  80  and the geometric body  81 . As shown, the geometric has a recessed cavity  82  which allows the geometric body  81  to nest comfortably in the frame  80  and keep it in position.  FIG.  9   b    shows the geometric body  81  securely nested in the recessed cavity  82 . Additionally, the frame further has a plurality of apertures  83  for connecting one geometric frame  80  to another. In one embodiment, the geometric body  81  is composed of foam or fabric. However, one having skill in the art will recognize that the geometric body  81  can be any number of materials suitable for constructing the geodesic dome, including but not limited to, metal, plastic, polymer, wood, electronic material (including display screens), cardboard, and glass. Similarly, the frame itself can also be constructed from any one or more of several materials, including but not limited to, metal, plastic, polymer, foam, wood, cardboard, and glass. 
       FIGS.  10   a  and  10   b    show two views of one embodiment of the present invention without the geodesic dome or raceway. The embodiment shown shows the workstation  1  with proper knee clearance  92  per ANSI Standards 8.3.2.1.2 for a 5% female in the seated position.  FIGS.  10   a  and  10   b    further utilize an imaginary user clearance box  93  to visualize the required clearance for a 5% female in the seated position. Additionally,  FIGS.  10   a  and  10   b    show cable receiving apertures  84 . The raceway of the present invention rests on top of the work surface  31  such as to conceal the cable receiving apertures  84  and any cables which may be present. 
       FIGS.  11   a  and  11   b    show a bottom view and top view, respectively, of one embodiment of the present invention without the geodesic dome.  FIGS.  11   a  and  11   b    show, by way of non-limiting example, how the cable receiving apertures  84  are utilized in the present invention.  FIG.  11   a    shows cables  85  extending from a first electronic device  86 . The cables  85  extend through the cable receiving apertures  84  on the underside of the work surface  31  and emerge from the cable receiving apertures  84  on the top side of the work surface  31 , shown in  FIG.  11   b   . The cables  85  then extend from the cable receiving apertures  84  until they reach a second electronic device  87 , third electronic device  88 , fourth electronic device  89 , and so on depending on the number of electronic devices utilized. One skilled in the art will appreciate that the number of cables  85  and electronic devices utilized can be adjusted based on the needs of the user. 
       FIG.  12    shows another embodiment of the present invention without the geodesic dome in which a receptacle block  90  is utilized. As shown, a first cable portion  85   a  which connects multiple workstations together extends up through the cable receiving aperture  84  and proceeds until it connects with a receptacle block  90 . The cable  85   b  then continues where it extends down through the cable receiving aperture  84  where it goes on to connect to another workstation. The use of the cables  85  places the workstations in electrical and data communication with one another. The receptacle block  90  may be a power strip having any number of electrical outlets which are utilized to connect one or more electronic devices based on the needs of the user. 
       FIGS.  13   a  through  14   d    show one embodiment of the acoustical dome  4  and of the geometric pieces  41  that make up the acoustical dome. The acoustical dome  4  shields the user from other users who may be located adjacent to the workstation  1 . The acoustical dome  4  is constructed from selectively interconnecting geometric pieces  41 . Shown are an acoustical dome  4  and component geometric pieces  41  thereof from an embodiment in which the acoustical dome  4  is a dome comprising arcuate pieces  41  which may, or may not, interconnect and/or be in flush physical contact with one another; in some embodiments, it may be desirable for the acoustical dome  4  to be constructed with gaps between at least one pair of adjacent pieces  41 , e.g. to allow ambient light and/or airflow to enter the area of the workstation  1  from above the dome  4  while still maintaining visual and acoustic separation of the workstation  1  from the surrounding environment. In the embodiment illustrated in  FIGS.  13   a    through  14   d,  each piece  41  comprises a plurality of rectangular or trapezoidal elements arranged in series; the pieces  41  are constructed such that each rectangular or trapezoidal element is disposed at a slight vertical angle relative to the succeeding rectangular or trapezoidal element, and such that a width or depth of each rectangular or trapezoidal element generally increases from the edge of the piece  41  toward the center. The overall effect of this construction is to provide each piece  41  with a generally arcuate shape that is narrowest at its edges (i.e. the lowest point, or “bottom,” of the piece  41 , disposed toward a periphery of the piece  41  and thus of the workstation  1 ) and widest at its center (i.e. the highest point, or “top,” of the piece  41 , disposed toward a center of the piece and thus of the workstation  1 ). However, one skilled in the art will recognize that the pieces  41  may be pentagonal, hexagonal, heptagonal, or any other geometric shape. Additionally, the acoustical dome may be created using a combination of two or more geometric pieces  41  with a different geometric shape, as in  FIGS.  13   a  through  14   d    (where each piece  41  is a combination of rectangular elements and trapezoidal elements having varying shapes). Similarly, while an acoustical dome is a preferred embodiment of the present invention, one having skill in the art will recognize that the acoustical privacy shield  4  may be a cube, pyramid, cone, ellipse, or other shape based on the needs of the user, and that the pieces  41  may be of a variety of sizes to either increase or decrease the number of pieces  41  used in the dome  4 . As shown, the dome  4  extends above, and optionally behind, the user to improve privacy. 
       FIGS.  15   a  through  15   d    depict a novel workstation  1  layout for an open workspace environment utilizing the present invention. In a preferred embodiment, the workstations  1  may be arranged in a zigzag or offsetting arrangement. This arrangement allows for an efficient use of workspace in order to maximize the density of users without degrading the privacy of the users. Moreover, this arrangement utilizes the raceway of each workstation  1  to interconnect the units and cut down on “pile-up” of electrical cords. This arrangement also provides a unique office aesthetic when the workstations are positioned at different heights. This customization allows both the users and employers to fully optimize their work environments. 
       FIGS.  16   a  through  16   d    depict an embodiment of the acoustical dome  4  illustrated in  FIGS.  13   a  through  14   d    in which the acoustical dome is selectively reconfigurable between an expanded, raised, or extended configuration (as in  FIGS.  13   a  through  14   d   ) and a collapsed, lowered, or retracted configuration (as in  FIGS.  16   a  through  16   d   ). The selective reconfiguration of the acoustical dome  4  may be accomplished by a user of the workstation  1  by any suitable means; by way of non-limiting example, one or more pieces  41  of the acoustical dome  4  may be constructed so as to allow the user to move the pieces  41  by hand, and/or the acoustical dome  4  may be provided with one or more electrical and/or mechanical means (e.g. a servo motor) by which the pieces  41  may be moved between the configurations upon operation by the user of a button, switch, or other user input device of the workstation  1 . It is to be expressly understood that, in some embodiments, the acoustical dome  4  and/or one or more pieces  41  thereof may, but need not, be reconfigurable into any number of positions intermediate between the fully expanded/raised/extended configuration ( FIGS.  13   a  through  14   d   ) and the fully collapsed/lowered/retracted configuration ( FIGS.  16   a  through  16   d   ). In many embodiments, it may be advantageous for the pieces  41  to be configured to “nest” within each other when in the fully collapsed/lowered/retracted configuration, as shown in  FIGS.  16   a    through  16   d,  such that the pieces  41  occupy a minimal depth and/or area of the work surface  31  of the workstation  1 . 
     Acoustical domes  4  and pieces  41  thereof according to any of the embodiments illustrated in  FIGS.  13   a  through  16   d    may be constructed of any one or more suitable materials, including but not limited to carbon fiber, cardboard, electrically conductive materials (e.g. for a display screen), fabrics, foams, glass, metals, plastics, polymers, wood, and combinations and mixtures thereof. In some embodiments, it may be desirable for at least one, and optionally all, of the pieces  41  to be constructed primarily of a semi-rigid material to prevent deformation of the pieces  41 , which may be particularly desirable, e.g., where the acoustical dome  4  is selectively reconfigurable and/or where the arrangement and relative position of the pieces  41  provides a particular functionality (e.g. to allow ambient light and/or airflow to enter the area of the workstation  1  from above the acoustical dome  4 ). Additionally or alternatively, it may be advantageous in some embodiments, e.g. where a cost or environmental footprint of manufacturing of the acoustical dome  4  is to be minimized, for at least one, and optionally all, of the pieces  41  to be constructed primarily of a recycled material, e.g. a recycled plastic or polymer. Those of ordinary skill in the art, in view of this disclosure, will understand how to select an appropriate material for a desired application. 
       FIGS.  17   a  through  17   d    depict the workstation  1  of  FIGS.  16   a  through  16   d    without the acoustical dome. As shown, the base  2  includes two telescopic legs  21  each further having a support structure  22 . However, one skilled in the art would recognize that various base  2  structures may be used, including non-telescopic legs of various heights, a various number of legs, legs of various widths including legs which also serve as drawers, and wall-like legs. The base  2  and body  3  may be part of one integral workstation  1 , or the base  2  and body  3  may be selectively connectable for easy transportation. For example, in  FIG.  14   d   , the angle  5  of the work surface  31  of the workstation  1  can be adjusted. 
     The workstation  1  may further include a modesty skirt  32  which is connected to the perimeter of the body  3  and extends around the perimeter of the body  3 . One skilled in the art will appreciate that the modesty skirt  32  may be of various lengths and does not necessarily have to extend around the entire perimeter of the body  3 . The modesty skirt  32  may be comprised of a plurality of materials including but not limited to various plastics, fabrics, polymers, metals, cardboard, or other materials which provide privacy for the user. The modesty skirt  32  may be transparent, opaque, or may be designed such that the transparency may be chosen by the user. The height of the modesty skirt  32  may be varied depending on the needs of the user and based on the position of the workstation  1  relative to other workstations. Additionally, the modesty skirt  32  may be selectively removable or collapsible such that a user may remove it if the modesty skirt  32  is not necessary. Additionally or alternatively, the modesty skirt  32  may serve as a structural support for an acoustical dome  4 ; by way of non-limiting example, a bottom or lower portion of the acoustical dome  4  may rest atop and/or interconnect with the modesty skirt  32 , and/or, in embodiments in which the acoustical dome  4  is selectively reconfigurable as shown in  FIGS.  16   a    through  16   d,  the modesty skirt  32  may serve as a back or rest for pieces  41  of the acoustical dome  4  when the acoustical dome  4  is selectively collapsed, lowered, or retracted. In embodiments in which the acoustical dome  4  is selectively reconfigurable and constructed of pieces  41  of generally arcuate shape with increasing width toward the center, e.g. as shown in  FIGS.  13   a    through  14   d,  the modesty skirt  32  may have a similarly arcuate shape with an increasing height toward the center, such that pieces  41  of the acoustical dome  4  “fit” with, i.e. rest flush against and do not protrude above, the modesty skirt  32  when the acoustical dome is selectively collapsed, lowered, or retracted. 
       FIGS.  18   a ,  18   b ,  18   c ,  19   a ,  19   b ,  19   c ,  20   a ,  20   b , and  20   c    show three adjustable-height embodiments of workstations  1  according to the present invention—one including only a modesty skirt  32  without an acoustical dome  4  ( FIGS.  18   a - c   ), one including a fixed acoustical dome  4  ( FIGS.  19   a - c   ), and one including a collapsible acoustical dome  4  ( FIGS.  20   a - c   )—configured at a seated height ( FIGS.  18   a ,  19   a ,  20   a   ), an intermediate height ( FIGS.  18   b ,  19   b ,  20   b   ), and a standing height ( FIGS.  18   c ,  19   c ,  20   c   ). In these embodiments, the vertical height of the workstation  1  may be continuously adjustable, or discretely adjustable between predefined positions or “stops,” by any suitable user-operable means, e.g. an electronic control, a hand crank, one or more gas springs, one or more mechanical springs and/or any suitable user-operable means for height adjustment. 
       FIG.  21    shows the workstation  1  comprising a fixed (non-collapsible) acoustical dome  4  illustrated in  FIGS.  19   a - c   , and particularly the fixation points  42  at which each segment  41  is interconnected to adjacent segment(s)  41 . It is to be expressly understood that such interconnections can be accomplished via any suitable means known to those of ordinary skill in the art, including but not limited to dowels, screws, bolts and nuts, rivets, etc. 
       FIGS.  22   a - c    show a side view of the collapsible acoustical dome  4  illustrated in  FIGS.  20   a - c    in the collapsed position. As illustrated in  FIG.  22   a   , a curved bracket  221  connects to the innermost of the dome segments, rotates on pivot  225 , and passes through a slot in the work surface  31  to connect with a linkage system  227 . An actuator  224 , shown in a fully retracted position, is configured, when operated by a user, to push and/or pull the linkage at point  226  to rotate the innermost dome segment  222  between collapsed and deployed positions. 
       FIG.  22   b    shows the collapsible acoustical dome  4  in a position intermediate between the collapsed position and the deployed position. In  FIG.  22   b   , the actuator  224  is pushing the linkage to rotate the innermost dome segment  222 . When the innermost dome segment  222  has reached a predefined rotational position relative to the second-innermost dome segment  223 , a groove and pin system in the dome brackets  221  engages and begins to rotate dome segment  223  into place. 
       FIG.  22   c    shows the collapsible acoustical dome  4  in a fully deployed position. Actuator  224  is fully extended, having rotated the innermost segment of the dome  222  into its fully deployed position. The innermost segment  222  lifts the second-innermost segment  223  and third-innermost segment  228  into their fully deployed positions when the pins in each segment of the brackets engage with the end of each slot in the adjacent bracket. 
     In embodiments, a linkage system may be provided on both sides of the acoustical dome  4 , only one of which comprises an actuator, and the linkages may be interconnected by a bar that spans the work surface  31  and transfers the rotational force to the non-actuated side and linkage. This allows for symmetrical and even rotation of the innermost segment on both sides of the desk. Alternatively, synchronized actuators can be provided on each side of the dome (i.e. in association with each linkage system) for symmetrical rotation of the innermost segment. 
       FIG.  23   a  through  23   f    show the rotational bracket system which interconnects the dome segments. The innermost bracket  231  moves through a slot  232  in the work surface  31  to connect the innermost dome segment  222  to the actuated linkage system  227 . A pin  233  attached to the innermost bracket  231  and protruding through the innermost dome segment  222  into the adjacent bracket and dome segment moves rotationally through a slot  234  in the second-innermost bracket  235  until it reaches the end of the slot, where the rotational movement of the innermost bracket is transferred to the second-innermost bracket  235 . As the second-innermost bracket  235  rotates, a pin  236  fixed to the second-innermost bracket  235  rotates in a slot  237  in the third-innermost bracket  238  until it reaches the end of the slot  237 , whereupon it transfers the rotational movement into the third-innermost bracket  238 . The length of the slots establishes the rotational offset between segments, thereby assuring the correct position of each segment when the acoustical dome  4  is in the fully deployed configuration. 
     It is to be expressly understood that, although the embodiment illustrated in  FIGS.  22   a - 23   f    is depicted as having three dome segments and thus a linkage system comprising three brackets, the same construction of dome segments and brackets can be utilized, mutatis mutandis, to provide a dome having any suitable number of segments and corresponding brackets. By way of non-limiting example, the number of segments (and thus brackets) in an adjustable acoustical dome  4  may be two, three, four, or any integer more than four, within the scope of the present invention. 
     In embodiments of the acoustical dome  4  according to the present invention, part or all of the acoustical dome  4  and/or associated components (e.g. the modesty skirt  32 ) may be partially or entirely made of a sound-absorbing material, e.g. polyethylene terephthalate (PET). By way of first non-limiting example, at least an outer (environment-facing) surface of the acoustical dome  4  may comprise a sound-absorbing material to reduce the degree of ambient noise perceived by a user of the workstation  1 . By way of second non-limiting example, at least an inner (work surface-facing) surface of the acoustical dome  4  may comprise a sound-absorbing material to reduce the degree of noise generated by the user (e.g. by typing, conducting phone calls, etc.) perceived by persons in the environment surrounding the workstation  1 . It is particularly advantageous for such sound-absorbing materials to be partially or entirely recycled or recyclable materials, which provides superior environmental benefits relative to the solutions of the prior art. Those of ordinary skill in the art will appreciate and understand how to select an appropriate sound-absorbing material for a desired application, based at least in part on budgetary considerations and a desired configuration or layout of workstation(s). 
     Embodiments of the acoustical dome  4  according to the present invention may take any of several suitable forms. By way of first non-limiting example, the acoustical dome  4  may be a single acoustical or visual barrier integrally affixed to the workstation  1  (e.g. similar to the modesty skirt  32 ). By way of second non-limiting example, the acoustical dome  4  may be a dome of fixed configuration, height, and/or orientation. By way of third non-limiting example, the acoustical dome  4  may be a collapsible dome actuated manually (i.e. by hand by a user). By way of fourth non-limiting example, the acoustical dome  4  may be a collapsible dome actuated by any of several mechanical means, including but not limited to one or more electrically operated linear actuators, a gear system, a gas spring, a mechanical spring, or any other suitable mechanism for reconfiguring the acoustical dome  4 . In some collapsible embodiments of the acoustical dome  4 , individual segments of the acoustical dome  4  may be interconnected to one another via any one or more suitable affixation means (e.g. bracket(s), a pin-and-slot mechanism(s), etc.), such that movement of only a single segment of the acoustical dome  4  between a collapsed position and an extended position (or vice versa) causes other segments of the acoustical dome  4  to be repositioned thereby. It is to be expressly understood that these and other embodiments are within the scope of the present invention. 
       FIGS.  24   a  through  24   d    show one embodiment of the acoustical dome  4  and of the geometric pieces  41  that make up the acoustical dome, and  FIG.  25    shows the sections  240   a,b,c  and connectors  241  of a single piece  41  of this embodiment in exploded view. The acoustical dome  4  shields the user from other users who may be located adjacent to the workstation  1 . The acoustical dome  4  is constructed from selectively interconnecting geometric pieces  41 . Shown are an acoustical dome  4  and component geometric pieces  41  thereof from an embodiment in which the acoustical dome  4  is a dome comprising arcuate pieces  41  which may, or may not, interconnect and/or be in flush physical contact with one another; in some embodiments, it may be desirable for the acoustical dome  4  to be constructed with gaps between at least one pair of adjacent pieces  41 , e.g. to allow ambient light and/or airflow to enter the area of the workstation  1  from above the dome  4  while still maintaining visual and acoustic separation of the workstation  1  from the surrounding environment. In the embodiment illustrated in  FIGS.  24   a    through  25 , each piece  41  comprises a plurality of rectangular or trapezoidal elements arranged in series; the pieces  41  are constructed such that each rectangular or trapezoidal element is disposed at a slight vertical angle relative to the succeeding rectangular or trapezoidal element, and such that a width or depth of each rectangular or trapezoidal element generally increases from the edge of the piece  41  toward the center. The overall effect of this construction is to provide each piece  41  with a generally arcuate shape that is narrowest at its edges (i.e. the lowest point, or “bottom,” of the piece  41 , disposed toward a periphery of the piece  41  and thus of the workstation  1 ) and widest at its center (i.e. the highest point, or “top,” of the piece  41 , disposed toward a center of the piece and thus of the workstation  1 ). However, one skilled in the art will recognize that the pieces  41  may be pentagonal, hexagonal, heptagonal, or any other geometric shape. Additionally, the acoustical dome may be created using a combination of two or more geometric pieces  41  with a different geometric shape, as in  FIGS.  24   a    through  25  (where each piece  41  is a combination of rectangular elements and trapezoidal elements having varying shapes). Similarly, while an acoustical dome is a preferred embodiment of the present invention, one having skill in the art will recognize that the acoustical privacy shield  4  may be a cube, pyramid, cone, ellipse, or other shape based on the needs of the user, and that the pieces  41  may be of a variety of sizes to either increase or decrease the number of pieces  41  used in the dome  4 . As shown, the dome  4  extends above, and optionally behind, the user to improve privacy. 
     Acoustical domes  4  and pieces  41  thereof according to the embodiment illustrated in  FIGS.  24   a    through  25  may be constructed of any one or more suitable materials, including but not limited to carbon fiber, cardboard, electrically conductive materials (e.g. for a display screen), fabrics, foams, glass, metals, plastics, polymers, wood, and combinations and mixtures thereof. In some embodiments, it may be desirable for at least one, and optionally all, of the pieces  41  to be constructed primarily of a semi-rigid material to prevent deformation of the pieces  41 , which may be particularly desirable, e.g., where the acoustical dome  4  is selectively reconfigurable and/or where the arrangement and relative position of the pieces  41  provides a particular functionality (e.g. to allow ambient light and/or airflow to enter the area of the workstation  1  from above the acoustical dome  4 ). Additionally or alternatively, it may be advantageous in some embodiments, e.g. where a cost or environmental footprint of manufacturing of the acoustical dome  4  is to be minimized, for at least one, and optionally all, of the pieces  41  to be constructed primarily of a recycled material, e.g. a recycled plastic or polymer. Those of ordinary skill in the art, in view of this disclosure, will understand how to select an appropriate material for a desired application. 
     The embodiment of the acoustical dome  4  illustrated in  FIGS.  24   a    through  25  differs from the embodiment of the acoustical dome  4  illustrated in  FIGS.  13   a  through  14   d    in that the pieces  41  that make up the acoustical dome  4  are not of unitary construction, as in  FIGS.  13   a    through  14   d.  Rather, in the embodiment illustrated in  FIGS.  24   a    through  25 , each piece  41  comprises a plurality of sections, in this case three sections  240   a,b,c , which are joined together after manufacture by connectors  241 . This alternative construction provides several important advantages and benefits. Particularly, the present inventors have discovered that where the acoustical dome  4  is intended to be used in conjunction with a particularly wide workstation  1 , e.g. a workstation  1  including two or three large computer monitors arranged in a single row, it may be impossible or impractical to manufacture unitary pieces  41  having sufficient length to span the entire width of the workstation  1  out of a selected material. To remedy this, the embodiment illustrated in  FIGS.  24   a    through  25  allows each piece  41  to be manufactured as a plurality of sections, in this case three sections  240   a,b,c , that are joined together after manufacture; this allows each section to have a length that is practical for manufacture. It is to be expressly understood that pieces  41  of acoustical domes  4  according to the embodiment illustrated in  FIGS.  24   a    through  25  may have any number of sections  240  equal to or greater than two, e.g. two, three, four, or greater than four. 
     In the embodiment illustrated in  FIGS.  24   a    through  25 , the connector  241  is a substantially rigid elongate component that is “bent” or “kinked” at such an angle as to provide for a corresponding angle of engagement between adjacent sections  240   a,b  and  240   b,c  of each piece  41 . One non-limiting example of such a connector  241 , as illustrated in  FIGS.  24   a    through  25 , is a “clip”-type connector that engages notches  242  provided in each section and thus slips onto each section  240  to a sufficient depth to hold each section  240  securely, but it is to be expressly understood that any suitable type of connector or fastener, as will be known in the art, may be employed to affix, fasten, or interconnect the sections  240  of each piece  41  to one another. One non-limiting example of a suitable method for manufacturing connectors  241  is injection molding, i.e. where the connector  241  is made of a plastic material, but any suitable material or manufacturing method for connector  241  may be employed; in all cases, however, connectors  241  should be constructed to have sufficient rigidity, tensile strength, etc. to hold the sections  240  of each piece  41  in place without breaking or otherwise failing as a result of the weight of each section  240 . 
     In the embodiment illustrated in  FIGS.  24   a    through  25 , the outermost piece  410  of the acoustical dome  4  may be affixed, by any suitable means, to an outer edge of a perimeter of the body  3  of the workstation  1 . Such a construction allows a bottom edge of the outermost piece  410  to extend below the work surface  31  to provide a modesty block for the operator and/or to better conceal cables or other electrical or mechanical components underneath the work surface  31 .
