FIELD OF THE INVENTION
Various embodiments of the invention described herein relate to the field of systems, devices, components, and methods for bone conduction and other types of hearing aid devices.
BACKGROUND
A magnetic bone conduction hearing aid is held in position on a patient's head by means of magnetic attraction that occurs between magnetic members included in the hearing aid and in a magnetic implant that has been implanted beneath the patient's skin and affixed to the patient's skull. Acoustic signals originating from an electromagnetic transducer located in the external hearing aid are transmitted through the patient's skin to bone in the vicinity of the underlying magnetic implant, and thence through the bone to the patient's cochlea. In some patients, it may be difficult to ascertain or determine how best to adjust the hearing aids' performance or functional characteristics, or positioning on the patient's skull, to optimize hearing in the patient. Patient feedback can be valuable in such a process of optimization, but may also be ambiguous, uncertain or misleading.
What is needed is a magnetic hearing aid system that somehow provides an improved ability to monitor or determine what the patient is actually hearing, or what the characteristics of the sound signals being generated by the hearing aid actually are.

DETAILED DESCRIPTIONS OF SOME EMBODIMENTS
Described herein are various embodiments of systems, devices, components and methods for bone conduction and/or bone-anchored hearing aids.
A bone-anchored hearing device (or “BAHD”) is an auditory prosthetic device based on bone conduction having a portion or portions thereof which are surgically implanted. A BAHD uses the bones of the skull as pathways for sound to travel to a patient's inner ear. For people with conductive hearing loss, a BAHD bypasses the external auditory canal and middle ear, and stimulates the still-functioning cochlea via an implanted metal post. For patients with unilateral hearing loss, a BAHD uses the skull to conduct the sound from the deaf side to the side with the functioning cochlea. In most BAHA systems, a titanium post or plate is surgically embedded into the skull with a small abutment extending through and exposed outside the patient's skin. A BAHD sound processor attaches to the abutment and transmits sound vibrations through the external abutment to the implant. The implant vibrates the skull and inner ear, which stimulates the nerve fibers of the inner ear, allowing hearing. A BAHD device can also be connected to an FM system or iPod by means of attaching a miniaturized FM receiver or Bluetooth connection thereto.
BAHD devices manufactured by COCHLEARTM of Sydney, Australia, and OTICONTM of Smoerum, Denmark. SOPHONOTM of Boulder, Colo. manufactures an Alpha 1 magnetic hearing aid device, which attaches by magnetic means behind a patient's ear to the patient's skull by coupling to a magnetic or magnetized bone plate (or “magnetic implant”) implanted in the patient's skull beneath the skin.
Surgical procedures for implanting such posts or plates are relatively straightforward, and are well known to those skilled in the art. See, for example, “Alpha I (S) & Alpha I (M) Physician Manual—REV A S0300-00” published by Sophono, Inc. of Boulder, Colo., the entirety of which is hereby incorporated by reference herein.
FIGS. 1(a), 1(b) and 1(c) show side cross-sectional schematic views of selected embodiments of prior art SOPHONO® ALPHA 1TM, BAHA® and AUDIANT® bone conduction hearing aids, respectively;
In FIG. 1(a), magnetic hearing aid device 10 comprises housing 107, electromagnetic/bone conduction (“EM”) transducer 25 with corresponding magnets and coils, digital signal processor (“DSP”) 80, battery 95, magnetic spacer 50, magnetic implant or magnetic implant bone plate 20. As shown in FIGS. 1(a) and 2(a), and according to one embodiment, magnetic implant 20 comprises a frame 21 (see FIG. 3(a)) formed of a biocompatible metal such as medical grade titanium that is configured to have disposed therein or have attached thereto implantable magnets or magnetic members 60.
Bone screws 15 secure or affix magnetic implant 20 to skull 70, and are disposed through screw holes 23 positioned at the outward ends of arms 22 of magnetic implant frame 21 (see FIG. 3(a)).
Magnetic members 60a and 60b are configured to couple magnetically to one or more corresponding external magnetic members or magnets 55 mounted onto or into, or otherwise forming a portion of, magnetic spacer 50, which in turn is operably coupled to EM transducer 25 and metal disc 40. DSP 80 is configured to drive EM transducer 25, metal disk 40 and magnetic spacer 50 in accordance with external audio signals picked up by microphone 85. DSP 80 and EM transducer 25 are powered by battery 95, which according to one embodiment may be a zinc-air battery, or may be any other suitable type of primary or secondary (i.e., rechargeable) electrochemical cell such as an alkaline or lithium battery.
As further shown in FIG. 1(a), magnetic implant 20 is attached to patient's skull 70, and is separated from magnetic spacer 50 by patient's skin 75. Hearing aid device 10 of FIG. 1(a) is thereby operably coupled magnetically and mechanically to plate 20 implanted in patient's skull 70, which permits the transmission of audio signals originating in DSP 80 and EM transducer 25 to the patient's inner ear via skull 70.
FIG. 1(b) shows another embodiment of hearing aid 10, which is a BAHA® device comprising housing 107, EM transducer 25 with corresponding magnets and coils, DSP 80, battery 95, external post 17, internal bone anchor 115, and abutment member 19. In one embodiment, and as shown in FIG. 1(b), internal bone anchor 115 includes a bone screw formed of a biocompatible metal such as titanium that is configured to have disposed thereon or have attached thereto abutment member 19, which in turn may be configured to mate mechanically or magnetically with external post 17, which in turn is operably coupled to EM transducer 25. DSP 80 is configured to drive EM transducer 25 and external post 17 in accordance with external audio signals picked up by microphone 85. DSP 80 and EM transducer 25 are powered by battery 95, which according to one embodiment is a zinc-air battery (or any other suitable battery or electrochemical cell as described above). As shown in FIG. 1(b), implantable bone anchor 115 is attached to patient's skull 70, and is also attached to external post 17 through abutment member 19, either mechanically or by magnetic means.
Hearing aid device 10 of FIG. 1(b) is thus coupled magnetically and/or mechanically to bone anchor 115 implanted in patient's skull 70, thereby permitting the transmission of audio signals originating in DSP 80 and EM transducer 25 to the patient's inner ear via skull 70.
FIG. 1(c) shows another embodiment of hearing aid 10, which is an AUDIANT®-type device, where an implantable magnetic member 72 is attached by means of bone anchor 115 to patient's skull 70. Internal bone anchor 115 includes a bone screw formed of a biocompatible metal such as titanium, and has disposed thereon or attached thereto implantable magnetic member 72, which couples magnetically through patient's skin 75 to EM transducer 25. DSP 80 is configured to drive EM transducer 25 in accordance with external audio signals picked up by microphone 85. Hearing aid device 10 of FIG. 1(c) is thus coupled magnetically to bone anchor 115 implanted in patient's skull 70, thereby permitting the transmission of audio signals originating in DSP 80 and EM transducer 25 to the patient's inner ear via skull 70.
FIG. 2(a) shows one embodiment of a prior art functional electronic and electrical block diagram of hearing aid 10 shown in FIGS. 1(a) and 2(b). In the block diagram of FIG. 2(a), and according to one embodiment, DSP 80 is a SOUND DESIGN TECHNOLOGIES® SA3286 INSPIRA EXTREME® DIGITAL DSP, for which data sheet 48550-2 dated March 2009, filed on even date herewith in an accompanying Information Disclosure Statement (“IDS”), is hereby incorporated by reference herein in its entirety. The audio processor for the SOPHONO ALPHA 1 hearing aid is centered around DSP chip 80, which provides programmable signal processing. The signal processing may be customized by computer software which communicates with the Alpha through programming port 125. According to one embodiment, the system is powered by a standard zinc air battery 95 (i.e. hearing aid battery), although other types of batteries may be employed. The SOPHONO ALPHA 1 hearing aid detects acoustic signals using a miniature microphone 85. A second microphone 90 may also be employed, as shown in FIG. 2(a). The SA 3286 chip supports directional audio processing with second microphone 90 to enable directional processing. Direct Audio Input (DAI) connector 150 allows connection of accessories which provide an audio signal in addition to or in lieu of the microphone signal. The most common usage of the DAI connector is FM systems. The FM receiver may be plugged into DAI connector 150. Such an FM transmitter can be worn, for example, by a teacher in a classroom to ensure the teacher is heard clearly by a student wearing hearing aid 10. Other DAI accessories include an adapter for a music player, a telecoil, or a Bluetooth phone accessory. According to one embodiment, DSP 80 or SA 3286 has 4 available program memories, allowing a hearing health professional to customize each of 4 programs for different listening situations. The Memory Select Pushbutton 145 allows the user to choose from the activated memories. This might include special frequency adjustments for noisy situations, or a program which is Directional, or a program which uses the DAI input.
FIG. 2(b) shows one embodiment of a prior art wiring diagram for a SOPHONO ALPHA 1 hearing aid manufactured using the foregoing SA3286 DSP. Note that the various embodiments of hearing aid 10 are not limited to the use of a SA3286 DSP, and that any other suitable CPU, processor, controller or computing device may be used. According to one embodiment, DSP 80 is mounted on a printed circuit board 155 disposed within housing 107 of hearing aid 10.
In some embodiments, the microphone incorporated into hearing aid 10 is an 8010T microphone manufactured by SONION®, for which data sheet 3800-3016007, Version 1 dated December, 2007, filed on even date herewith in the accompanying IDS, is hereby incorporated by reference herein in its entirety. Other suitable types of microphones, including other types of capacitive microphones, may be employed.
In still further embodiments, the electromagnetic transducer 25 incorporated into hearing aid 10 is a VKH3391W transducer manufactured by BMH-Tech® of Austria, for which the data sheet filed on even date herewith in the accompanying IDS is hereby incorporated by reference herein in its entirety. Other types of suitable EM or other types of transducers may also be used.
FIGS. 3(a), 3(b) and 3(c) show implantable bone plate or magnetic implant 20 in accordance with FIG. 1(a), where frame 22 has disposed thereon or therein magnetic members 60a and 60b, and where magnetic spacer 50 of hearing aid 10 has magnetic members 55a and 55b spacer disposed therein. The two magnets 60a and 60b of magnetic implant 20 of FIG. 2(a) permit hearing aid 10 and magnetic spacer 50 to be placed in a single position on patient's skull 70, with respective opposing north and south poles of magnetic members 55a, 60a, 55b and 60b appropriately aligned with respect to one another to permit a sufficient degree of magnetic coupling to be achieved between magnetic spacer 50 and magnetic implant 20 (see FIG. 3(b)). As shown in FIG. 1(a), magnetic implant 20 is preferably configured to be affixed to skull 70 under patient's skin 75. In one aspect, affixation of magnetic implant 20 to skull 75 is by direct means, such as by screws 15. Other means of attachment known to those skilled in the art are also contemplated, however, such as glue, epoxy, and sutures.
Referring now to FIG. 3(b), there is shown a SOPHONO® ALPHA 1® hearing aid 10 configured to operate in accordance with magnetic implant 20 of FIG. 3(a). As shown, hearing aid 10 of FIG. 3(b) comprises upper housing 111, lower housing 115, magnetic spacer 50, external magnets 55a and 55b disposed within spacer 50, EM transducer diaphragm 45, metal disk 40 connecting EM transducer 25 to spacer 50, programming port/socket 125, program switch 145, and microphone 85. Not shown in FIG. 3(b) are other aspects of the embodiment of hearing aid 10, such as volume control 120, battery compartment 130, battery door 135, battery contacts 140, direct audio input (DAI) 150, and hearing aid circuit board 155 upon which various components are mounted, such as DSP 80.
Continuing to refer to FIGS. 3(a) and 3(b), frame 22 of magnetic implant 20 holds a pair of magnets 60a and 60b that correspond to magnets 55a and 55b included in spacer 50 shown in FIG. 3(b). The south (S) pole and north (N) poles of magnets 55a and 55b, are respectively configured in spacer 50 such that the south pole of magnet 55a is intended to overlie and magnetically couple to the north pole of magnet 60a, and such that the north pole of magnet 55b is intended to overlie and magnetically couple to the south pole of magnet 60b. This arrangement and configuration of magnets 55a, 55b, 60a and 60b is intended permit the magnetic forces required to hold hearing aid 10 onto a patient's head to be spread out or dispersed over a relatively wide surface area of the patient's hair and/or skin 75, and thereby prevent irritation of soreness that might otherwise occur if such magnetic forces were spread out over a smaller or more narrow surface area. In the embodiment shown in FIG. 3(a), frame 22 and magnetic implant 20 are configured for affixation to patient's skull 70 by means of screws 15, which are placed through screw recesses or holes 23. FIG. 3(c) shows an embodiment of hearing aid 10 configured to operate in conjunction with a single magnet 60 disposed in magnetic implant 20 per FIG. 1(a).
Referring now to FIGS. 4 through 9, there are shown various embodiments and views of sound acquisition device 300.
FIG. 4 shows a cross-sectional view of one embodiment of sound acquisition device 300 operably coupled to hearing aid 10 and disposed thereabove, and magnetic implant 20 disposed beneath patient's skin 75 and attached to patient's skull 70 therebelow, where sound acquisition device 300, magnetic implant 20, hearing aid 10 (which includes magnetic spacer 50), and processing and analyzing means 350 together comprise sound acquisition, processing and analyzing system 400.
Continuing to refer to FIG. 4, and in one embodiment, hearing aid 10, sound acquisition device 300, and magnetic implant 20 together comprise portions of sound acquisition, processing and analyzing system 400. Electromagnetic (“EM”) transducer 25 is disposed in housing 107 of hearing aid 10, and magnetic spacer 50 is operably coupled to EM transducer 25 and comprises magnetic members 50a and 50b, or any other suitable configuration of magnets (as for example discussed above or in the above-referenced the '057 and '934 patent applications). As described above, housing 107 and magnetic spacer 50 form external portions of magnetic hearing aid 10.
In the embodiment of system 400 shown in FIG. 4, magnetic implant 20 is configured for placement beneath patient's skin 75 and adjacent to or in a patient's skull 70. Magnetic implant 20 comprises magnetic members 60a and 60b, or any other suitable configuration of magnets (as for example discussed above or in the above-referenced the '057 and '934 patent applications). Magnetic spacer 50 and magnetic implant 20 are together configured such that magnetic members 50a, 50b, 60a and 60b are capable of holding magnetic hearing aid 10 in position on patient's skull 70 over at least portions of implanted magnetic implant 20.
System 400 of FIG. 4 further comprises sound acquisition device 300 configured to be positioned between magnetic spacer 50 and magnetic implant 20, and to be magnetically coupled both to magnetic spacer 50 and to magnetic implant 20 via magnetic members 250a, 250b, 251a and 251b. Sounds generated by EM transducer 25 in hearing aid 10 are acquired using sound sensor 257 forming a portion of sound acquisition device 300 (see, e.g., sound sensor 257 in FIGS. 5 and 7) as the sounds pass through sound acquisition device 300 into patient's skull 70.
Referring now to FIG. 5, there is shown an exploded top perspective view according to of one embodiment of sound acquisition device 300. As shown in the FIG. 5, sound acquisition device 300 comprises top plate 250, magnetic holder 233, surrounding seal 237, and bottom plate 203. Top plate 250 and post 260 are configured to fit matingly below and against bottom corresponding portions of overlying magnetic spacer 50. Top plate 250, magnetic holder 233, and magnetic members 250a and 250b together comprise upper portion 270 of sound acquisition device 300. Top plate 250 may be incorporated into or onto magnetic holder 233 such that magnetic holder 233, magnetic members 250a and 250b, and top plate 250 form a single integral, molded or glued-together module.
In FIG. 5, magnetic members 250a and 250b are configured to be disposed within corresponding recesses 235a and 235b of magnetic holder 233. Many different numbers, variations, combinations and configurations of magnetic members 250 may be employed in sound acquisition device 300, as described above, and as those skilled in the art will appreciate after having read and understood the present specification. Magnetic members 251a and 251b are configured to be disposed in recesses 205 and 207 of bottom plate 203.
According to one embodiment, and as shown in FIG. 5, seal 237 is disposed between the upper and lower portions of sound acquisition device 300, where upper portion 270 of sound acquisition device 300 is attached to top portions of seal 237, and lower portion 280 of sound acquisition device 300 is attached to bottom portions of seal 237. Such attachments to surrounding seal 237 may be made by any one of suitable mechanical attachments means known to those skilled in the art, such as by using a suitable adhesive, silicone, screws, nuts and bolts, or the like. In some embodiments, seal 237 is formed of a pliable, compressible, resilient material such as silicone, rubber, an elastomer or similar material, and forms a seal protecting interior portions of sound acquisition device 300 from the ingress of ambient humidity, oils, water, chemicals, and so on. In one embodiment, and as shown in FIG. 5, bottom plate 203, sound sensor 257, magnetic members 251a and 251b, and seal 237 together comprise lower portion 280 of sound acquisition device 300.
In one embodiment, magnetic spacer 50 and sound acquisition device 300 are together configured to be magnetically coupled to one another via magnetic members 50a and 50b and corresponding magnetic members 250a, 250b, 250c and 250d, and magnetic implant 20 and sound acquisition device 300 are together configured to be magnetically coupled to one another via magnetic members 251a and 251b and corresponding magnetic members 60a and 60b. 
In one embodiment, magnetic members 250a and 250b and magnetic members 251a and 251b of sound acquisition device 300 have suitable magnetic strengths and magnetic pole arrangements and positioning such that magnetic holder 233 may be magnetically coupled to and held in an operable position with respect to underlying bottom plate 203. In still further embodiments, magnetic members 250a and 250b and magnetic members 251a and 251b of sound acquisition device 300 are not configured to magnetically couple to one another, and upper and lower portions 270 and 280 are mechanically held together by adhesives, screws, bolts and nuts, or the like.
Continuing to refer to FIG. 5, there is also shown sound sensor 257, which is configured to be disposed atop central post or support 209, and sandwiched between central post or support 209 and underside 239 of magnetic holder 233 in an operable position, more about which is said below. In one embodiment, sound sensor 257 is glued to central post or support 209. According to some embodiments, sound sensor 257 is a piezoelectric sensor configured to convert sounds incident thereon and passing therethrough into corresponding electrical output signals. Other types of sound sensors may also be employed in sound acquisition device 300, as those skilled in the art will appreciate after having read and understood the present specification, such as membranes, diaphragms, accelerometers, velocity sensors, electromagnetic spring, coil and magnet sensors, and so on. Positive and negative connections are shown schematically in FIG. 5 as being attached to piezoelectric sensor 257, where such connections are used to route output signals from sensor 257 to an external device such as a processing and analyzing means 350 capable of receiving, processing, storing and/or analyzing the received output signals.
Referring now to FIGS. 6(a), 6(b), 6(c) and 6(d), there are shown top, side, side perspective, and end views according to one embodiment of magnetic holder 233. As particularly shown in FIG. 6(b), magnetic holder 233 comprises a curved acoustic sensor bending surface 239, which is configured and shaped to bend a first or top surface of piezoelectric sensor 257 along a curved surface defined by acoustic sensor bending surface 239 when sensor 257 is positioned operably between surface 239 and post 209, with its second or bottom surface engaging central support or post 209. The resulting bent or curved configuration of piezoelectric sensor 257 along curved surface 239 results in significantly enhanced and heightened sensitivity of piezoelectric sensor 257 to sounds being incident thereon and passing therethrough. Such enhanced and heightened sensitivity and increased response to incident sound waves results at least partially because piezoelectric sensor 257 is positioned and held in a pre-stressed state by curved surface 239. In one embodiment, curved acoustic surface 239 has a radius ranging between about 6 inches and about 8 inches. Other radii are contemplated, however, where the particular radius selected depends on factors such on the diameter D of piezoelectric sensor (see FIG. 7), the performance characteristics of the piezoelectric sensor that is to be selected, and the thickness t of the piezoelectric sensor (see FIG. 7).
In one embodiment, and as shown in FIGS. 5 and 7, piezoelectric sensor 257 is disk-shaped or circular-shaped and has a diameter ranging between about 0.4 inches and about 1 inch In other embodiments, piezoelectric sensor 257 has an elliptical, rectangular, square or other shape. According to some embodiments, piezoelectric sensor 257 has a thickness ranging between about 0.2 mm and about 0.8 mm.

FIG. 7 shows a partially assembled top perspective view of sound acquisition device 300. Top plate 250 has been joined with and mated to underlying magnetic holder 233, and magnet members 250a and 250c have been inserted within magnetic holder 233, to form upper portion 270 of sound acquisition device 300. Piezoelectric sensor 257, and magnetic members 251a and 251b remain yet to be inserted in bottom plate 203, while seal 237 has been attached to bottom plate 203. Seal 237, magnetic members 251a and 251b, piezoelectric sensor 257, and bottom plate 203 together comprise lower portion 280 of sound acquisition device 300.
FIG. 8 shows one embodiment of sound acquisition device 300 in a fully assembled form, where upper and lower portions 270 and 280 have been joined together to form a single device. Unit, module or device 300 may then be positioned between hearing 10 and magnetic implant 20, and provides direct measurements of the sounds transmitted by hearing aid 10 into the patient's skull 70.
Referring now to FIGS. 5, 7 and 8, seal 237 and upper and lower portions 270 and 280 of sound acquisition device 300 may also be configured so that upper portion 270 may be removed by a user from lower portion 280 and so that sound sensor 257 disposed therewithin may be adjusted or replaced with a sound sensor having different operating and physical characteristics (e.g., higher or lower sensitivity, greater or lesser diameter D, or greater or lesser thickness t—See FIG. 7). FIG. 9 shows a cross-sectional view of fully-assembled sound acquisition device 300 of FIG. 8. As shown, adhesive or silicone 215a and 215b, or any other suitable mechanical attachment means, connects seal 257 to top portion 270 and to bottom portion 280.
Referring now to FIGS. 4 and 10, one embodiment of sound acquisition, processing and analyzing system 400 comprises hearing aid 10 (which includes magnetic spacer 50), sound acquisition device 300, magnetic implant 20, where hearing aid 10, sound acquisition device 300, and magnetic implant 20 are all operably and magnetically coupled to one another, as well as to the patient's skull 70, and sound processing and analyzing system 350. Sounds or acoustic signals generated by piezoelectric sensor 257 in sound acquisition device 300 while transducer 25 of hearing aid 10 is generating output signals to be heard by a patient are transferred via connection 307 to amplifier 330, ND interface 320, and computer 310. (Note that any one or more of amplifier 330, A/D interface 320, and D/A interface 340 shown in FIG. 4 may be included in or form a portion of computer 310.) Electrical signals generated by sensor 257 in response to sounds generated by transducer 25 being incident thereon or passing therethrough are sent to system 350 for processing and analysis. Such transfer may be accomplished using hard-wiring, or by wireless means, including but not limited to, Bluetooth means. In a wireless embodiment, sound acquisition device can be configured to include, for example, Bluetooth transmitters and/or receivers. Amplifier 330 in system 350 may or may not be required, depending on the amplitude of the output signals provided by sensor 257. Amplifier 330 may also be included in or form a portion of sound acquisition device 300.
Once data corresponding to sounds acquired by sound acquisition device 300 have been stored in a memory or other storage device of computer 310, such data may be processed and analyzed in computer 310 to yield various types of information regarding the acquired sound signals, such as their frequency, amplitude and phase characteristics using, for example, well known FFT and other digital signal processing techniques applied to the acquired acoustic signals. Spectral and other characteristics of the processed sound signals can be employed to determine, by way of non-limiting example, whether hearing aid 10 is coupled sufficiently or insufficiently to patient's skull 70, whether sound signals generated by hearing aid 10 have sufficient amplitude to be heard by the patient, or whether ambient acoustic noise should or should be reduced using a notch or other type of filter. Many other problems with hearing aid 10, magnetic implant 20, and/or the patient can thus be discovered and diagnosed through the use of sound acquisition device 300 and data processing and analyzing system 350.
As further shown in FIG. 4, computer 310 may also be operably connected to hearing aid 10 through D/A interface 340, and may be programmed and configured to generate electrical signals to drive EM transducer 25 in hearing aid 10 in accordance with desired operating parameters. Computer 310 may further be operably connected to hearing aid 10 through programming port 125 (see, e.g., FIG. 2(a) to program or re-program hearing aid 10 in accordance with the results of analysis of sounds acquired using sound acquisition device 300. Connection 309 between D/A interface 340 and hearing aid 10, and/or between computer 310 and hearing aid 10, may be provided by hard-wiring, or by wireless means, including but not limited to Bluetooth means. In one embodiment, connection 309 may be established with hearing aid 109 via programming port 125 or another suitable port on hearing aid 10. Processing and analyzing system 350 and/or computer 310 may thus be programmed to provide means for adjusting the output or response of hearing aid 10 and EM transducer. Such output or response adjustment of hearing aid 10 may include one or more of adjusting or calibrating the amplitude, frequency, or phase response of hearing aid 10 to ambient acoustic signals detected thereby, and/or to adjust the amplitude, frequency, or phase transfer functions of EM transducer 25.

Thus, a mobile electronic device or mobile smartphone can be employed by a patient or a health care provider to monitor the performance of hearing aid 10.
Moreover, sounds or acoustic signals acquired using sound acquisition device 300 may be processed and analyzed using a mobile electronic device, a mobile phone, a laptop computer, a desktop computer, a notebook computer, a local server, a remote server, or the cloud. Results obtained by processing and analyzing the acquired sounds or acoustic signals may be visually displayed in any of a number of ways known to those skilled in the art, such as by displaying the results on a computer monitor or display, the screen of a mobile electronic device, mobile phone or smartphone, a laptop computer, a desktop computer, or a notebook computer.

Alternatively, such acquired signals from sound acquisition device 300 may be transferred to computer 310 or other device while hearing aid 10 is magnetically coupled to sound acquisition device 300, and sound acquisition device 300 is magnetically coupled to magnetic implant 20, where magnetic implant 20 is implanted in or on a test fixture so as to measure the performance of hearing aid 10 under calibrated and known magnetic and mechanical coupling and resonance conditions.
Depending on the results provided by the processed and analyzed sounds or acoustic signals, sound control or calibration signals may be generated in computer 310 and provided to magnetic hearing aid 10 such that EM transducer 25 is driven in accordance with the desired or predetermined sound control or calibration signals. Such predetermined sound control or calibration signals may be stored or generated in computer 310, or stored or generated in a mobile electronic device, a mobile phone, a laptop computer, a desktop computer, a notebook computer, a local server, a remote server, or the cloud, and then made available for use in calibrating or driving hearing aid 10. As mentioned above, a frequency response of hearing aid 10 and/or transfer functions of EM transducer 25 may be determined by computer 310 using the acquired sounds, as may amplitude and phase responses. In response to determining and analyzing such frequency, amplitude or phase responses of hearing aid 10 and/or transfer functions of EM transducer 25, computer 310 or other device (as described above) may be programmed to adjust or change any one or more of such responses, or may further be programmed to program or re-program parameters in hearing aid 10 in accordance with results provided by the analyzed sounds or acoustic signals.
