Sound resistant enclosure

## Abstract

A sound resistant enclosure apparatus adapted for a person have access to an environment that reduces sound from ambient noise. More particularly, the invention relates to a manner in which to use common fabrication materials and method to construct a sound resistant enclosure or booth for use to make or receive cellular telephone calls in relative quiet. The apparatus include among its essential elements, a cylindrical outer wall, a cylindrical inner wall, a door, a top or roof, a floor and sound resistant material mostly deposited between the inner and outer walls. Sound resistant material can also be found in the door, roof and walls. The sound resistant enclosure blocking much of the ambient environmental noise such that the occupant of the enclosure can make or receive a cellular phone call more effectively and efficiently without having distracting unwanted extraneous environmental noise interrupting their conversation.

## Background
FIELD
The invention relates generally to a cylindrical sound resistant enclosure, the sound resistant enclosure is adapted such that a person can open the door to the enclosure, enter the enclosure, then close the door of the enclosure behind them so that the person is inside the enclosure thereby creating a sound resistant environment for the person. Once the person is inside the enclosure with the door closed the enclosure blocks substantially any exterior noise creating a relatively quiet environment blocking many audible noises. The enclosure creates a quiet environment for the occupant allowing the occupant to perform such tasks as converse on a cell phone without distraction from exterior noise. In addition the enclosure also creates an environment that allows for noise not to exit the sound resistant enclosure, whereas the occupant can converse on a cell phone inside the enclosure and someone outside the enclosure cannot hear the conversation. The enclosure, among other items includes a light and ventilation for comfort of the occupant, the enclosure also having a door and a ramp leading into the enclosure, such that the door and ramp accommodates a physically challenged individual so the physically impaired can use the booth, which includes a person in a wheelchair.
BACKGROUND
In the past, telephone booths or telephone booth enclosures where found in many locations around the world, many of these booths accessible to the public, the telephone booth generally contained a phone within and maybe a phone book. Many phone booths are designed as an enclosure for a person to enter and others are designed as an open booth that merely protect the phone itself not allowing a person to enter. The present invention is directed toward a booth that a person can enter and close himself or herself in the booth, separating themselves from the ambient environment, separate themselves from the ambient sound environment. Typically in the past when a person wished to make a phone call they entered a telephone booth closed the door behind them place money in the phone (or used other forms of payment to make a call such as credit card or collect call) dialed the phone and made a call. The past phone booths offered a shelter from the weather as well as a place to make a telephone call. Many prior art past booths were constructed of glass or plastic sheet, i.e. the booth having three flat walls a flat door and a floor and ceiling, booths are generally square elongated glass or glass like enclosures. The booths may have blocked some sound but are not constructed specifically to block sound. Booths where frequent in number and could be found in many location such as along busy streets, inside hotels, bars department stores, arenas and other location frequented by the public or even private use. Telephone booths not only gave an individual the access to a telephone but also gave the person a closed private space to make the call. Prior art booths do not contain a multi layered sound resistant material therein that blocks and deadens sounds but merely provides four walls for shelter. Some telephone booths where not enclosed but merely a three sided enclosure that did not provide as much privacy as a closed booth. Many examples of these booths can be seen in the prior art,
Prior art U.S. Pat. No. 3,063,496 discloses an invention for an outdoor telephone booth, more particularly a lightweight, rigidly assembled square shaped booth having walls or translucent plastic sheet material and having a door arrangement. Other prior art, U.S. Pat. No. 4,432,170 shows an invention for an outdoor telephone booth or type comprising a metal framework with transparent side panels and a light source in the ceiling of the booth for illuminating the booths interior. This booth comprises among other things two vertically elongated translucent side panels extending from the top to the bottom.
Most recently however telephone booths are quickly becoming a thing of the past, with the advent of mobile phones or wireless communications the need for telephone booths is quickly becoming obsolete. No longer does someone have to search for a phone booth that contains a phone to make a call when many people have portable hand held cellular phones and many more are procuring them. Today normally many people do not use a telephone that is fixed within a phone booth to make a call, they use a hand held portable wireless phone sometimes referred to as cellular phones which provides the user with virtually unlimited mobility to make a telephone call where ever the person is located. The person no longer has to search out a telephone booth, enter the telephone booth and make such a call. With portable phones the person merely picks up the hand held phone and places a call. However with the telephone booth becoming a thing of the past also becoming a thing of the past has been a place to go to make that call. Frequently, a person wishes to make a call in an atmosphere that is quiet so the caller can hear as well as speak to be heard. Having a hand held mobile phone sometimes this quiet comfortable place can be difficult to locate. With the advent of the hand held phone many environments exist that would be difficult to make a call so that the caller and person receiving the call can hear and converse in a normal manner. Conceivably many environments and situations exist in which making a cellular phone call would be difficult, the ambient noise surrounding the person making or receiving the call may be such that the person cannot hear or be heard, or in the alternative a quiet environment where a call can be made but someone nearby could easily over hear your call. One Good example of this type of environment would be a person located at a sporting event generally at a sports stadium, a location with many people in a relatively confined space. The person would make a call, place a call on their portable mobile phone, the noise, the crowd, and generally all the noise that comes with such a location would make it difficult if not impossible to hear anyone on the line or for the person to speak into the phone have the other person hear them. In the past the caller could have gone to an enclosed phone booth though not completely sound resistant provided some quiet to a caller could make a call. However as these telephone booths become less common the caller may find it difficult to find a quiet place to make a call. In yet an other example of a place difficult if not impossible to make a phone call and expecting to hear the call or have the person on the other end hear you would be just about any crowded public space. Such as walking up a busy street, or eating in a restaurant, or a bus station, or any locations having a gathering of persons that can be very noisy preventing someone from making a call because of the noise. In some cases at ticketed events such as sporting arena it may not be desirable to leave the arena to get to a quiet place to make a call, many arenas would not allow the person to re-enter. The inventor has seen and solved the need for a location in such environment to quickly and quietly make a phone call without having to go a distance to reach a quiet place to make a call.
Today, it is common that there are less and less phone booths available and more cell phones per person than ever before. People use mobile phones in every place they can carry one, more often people wish to make phone calls on there mobile phone in environments that may have noise, such as a sport stadium, night club, hotel lobby, or just about any public place that typically has lots of activity and lots of noise. Many times the caller wishes to find a location to make a call that would block out some of the exterior noise so the caller can successfully make the call without having to contend with extraneous noise. The inventor has seen the need for a quiet place to make such a portable phone call and has developed this solution. In addition to the present invention blocking outside noise so a caller can make a phone call the caller may also want a private place to make a call where no one can hear what the caller is saying during his conversion. It is common that people making calls in a public place can be over heard by other people, this invention of the sound resistant booth solves this problem.
In the past other phone booths or other prior arts did not provide the sound resistance that the inventors booth does, the inventors design provides for a cylindrical sound resistant booth for someone to enter and keep noise out or to keep others from hearing the call. In addition the inventor has made the booth accessible to handicapped persons.
SUMMARY
This invention provides an apparatus for a sound resistant enclosure wherein a person can enter the enclosure and get away from surrounding noise. More particularly embodiment of this invention relates to a manner is which to use common building materials and methods in the fabrication of a sound resistant enclosure more effectively and efficiently than in the past. Using embodiments and implementations of this invention will allow the user to construct and use a sound resistant enclosure. In most cases the person enters the sound resistant enclosure to participate in a phone conversation without having someone else nearby hear the conversation or the person can participate in a phone conversation protected from ambient surrounding noise. The present invention is directed toward construction and use of a sound resistant enclosure. Generally the construction of this enclosure is a cylindrical booth having sound resistant material within, a ramp, a door, an interior light and ventilation. A person wishing to go to a space that is quieter that the ambient surroundings opens the door to the booth enters the booth closes the door behind and now is enclosed in a quiet environment, once within the quiet environment the person perhaps can place or receive a cell phone call in relative peace and quiet without having a large amount of ambient noise to contend with or worry about someone nearby hearing or listening in on their conversation. One additional advantage of the booth enclosure is also a quiet private place to make such a call where no one else outside the enclosure can hear you provide the user with assurance that the conversation will not be overheard as easily as if being outside the enclosure.
The enclosure is substantially a cylindrical construction having a pocket door that slides between an outer wall structure and an inner wall structure, the enclosure also having a top and bottom. The invention may also include an inner light, ventilation and a ramp for easy access. Some illustrations of this invention are handicapped and physically impaired accessible. A sound resistant material is located between the inner and outer wall structures of the invention to reduce noise from getting into and out of the enclosure. Sound resistant material can also be located at the top an bottom of the enclosure.
The inventor has found that the most effective sound proofing material can be selected from common building materials such as fiberglass textile, continuous glass fibers, glass oxide chemicals, cotton fiber or any similar materials. The inner and outer walls can typically be fabricated using metal, plastic or even wood, any material that is rigid so the retain the shape. The door in general can be manufactured from at least one single piece of clear polycarbonate material or acrylic, the door can also be fabricated from the same or similar materials as the inner and outer walls then incorporating a window manufactured from a clear polycarbonate material or clear acrylic material, the door or door window being transparent so a person can see through it and to allow light into the enclosure. The cylindrical and disc shaped perforated sound shield is in general fabricated from perforated metal such as a mild steel or corrosion resistant steel commonly available, this perforations can be any shape that is through the shield.
It is an object of this invention to provide an apparatus and method of providing a sound resistant enclosure for perhaps making a cellular phone call out of ambient surroundings. More particularly the invention uses present technology of today's manufacturing methods and materials to accomplish the result of creating a sound resistant enclosure for a person to enter and be temporally isolated from ambient conditions.
One illustration of this invention embodies a handicapped accessible embodiment. Typically having a larger area to accommodate a wheel chair as well as a ramp to enter the booth.
