## Background
The present application claims benefit of Provisional Application Nos. 62/136,272 filed Mar. 20, 2015 and 62/194,780 filed Jul. 20, 2015; all of which are incorporated by reference herein.


BACKGROUND
According to the World Health Organization, over 5% of the world's population—360 million people—have disabling hearing loss (328 million adults and 32 million children). Approximately one-third of people over 65 years of age are affected by disabling hearing loss. Disabling hearing loss refers to hearing loss greater than 40 dB in the better hearing ear in adults and a hearing loss greater than 30 dB in the better hearing ear in children.
Hearing aids are electrical devices that assist in optimizing perception of speech or other sounds. Most hearing aids are designed for hearing impaired individuals, of which there are approximately 37 million in the United States. Hearing aid unit sales in 2013 came very close to topping the 3-million unit mark for the first time in industry history. Industry experts are projecting 4 million unit sales by 2020.
Even though hearing aids can have a substantial impact on mitigating hearing loss, use of hearing aids with mobile or cordless telephones can be problematic. The configuration of Behind the Ear (BTE) or Receiver in the Canal (RIC) hearing aids can impede transfer of the sound from the voice emitting speaker (or receiver) of telephones thereto. For example, the position of the microphones of BTE hearing aids is often removed from the traditional placement of the voice emitting speakers of such telephones adjacent the ear. To illustrate, a user of a BTE hearing aid can oftentimes hear the phone ring, but cannot clearly hear callers due to the BTE hearing aid ear mold obstruction preventing the transfer of sounds from the voice emitting speaker.
Therefore, there is a need for a device facilitating the transfer of sounds from the voice emitting speaker of a telephone to a hearing aid.
The assistive hearing device described herein is designed to improve communication on telephones, including cordless or mobile phones, for people who wear BTE or RIC hearing aids. The assistive hearing device eliminates the need to place a phone receiver behind the ear to obtain the clearest sound. The assistive hearing device redirects telephonic sound via an acoustical accumulator and director to the microphone of the hearing aid located behind the ear or in the ear canal of the user. The acoustical accumulator and director extends beyond the top of the phone whereby it redirects the telephonic sound from the phone closer to where the BTE or RIC microphone is located.
SUMMARY OF THE INVENTION
In its simplest form, the assistive hearing device consists of a small outer case having opposite top and bottom ends, with a sound entrance aperture proximate the bottom end of the assistive hearing device, which is coupled (preferably with an elastic band, an adhesive material, or a hook and loop fastener) to the phone and a sound exit aperture located proximate the top end of the assistive hearing device. The two apertures are located approximately 1.5 to 2 inches apart. The assistive hearing device does not require a power source and is easy to install. The assistive hearing device adheres to the receiver end of a phone via a small O-Gasket creating a secure and soundproof seal. The O-Gasket material used to adhere the device to the phone can be, for example, a custom made high-density polyethylene film with double-sided synthetic rubber adhesive or a high friction rubber material.
In accordance with the present invention, an assistive hearing device having a sound entrance aperture on a first side, the sound entrance aperture placed against a voice emitting speaker (or receiver) of the telephone, a sound egress aperture on a second side opposite the first side, and the sound egress aperture located within closer proximity to a hearing device relative to the sound entrance aperture and the speaker to facilitate transmission of sound from the speaker to the hearing device located nearby is provided. The assistive hearing device includes a hollow interior, which connects the sound entrance and sound egress apertures, and allows sound waves entering the sound entrance aperture to travel through the hollow interior and exit the sound egress aperture. The sound entrance aperture of the assistive hearing device surrounds the speaker of the mobile device to capture sound waves transmitted from the speaker. The transmitted sound waves enter the sound entrance aperture, traverse through the hollow interior of the assistive hearing device and exit the sound egress aperture, which is located within closer proximity to the hearing device microphone relative to the sound entrance aperture and to the telephone speaker.
While most telephone speakers are designed to be placed against the ear of a user adjacent to the ear opening leading to the ear canal, the assistive hearing device takes into account that many hearing devices are worn behind the ear, which is at the opposite side of the ear opening. Specifically, the sound egress aperture is located on an opposite side of the sound entrance aperture to direct sound waves that enter the sound entrance aperture to the sound egress aperture, which is in closer proximity and oriented on the same side with respect to the BTE hearing aid microphone.
The assistive hearing device may include an adhesive portion that contains an adhesive material that is bonded to a surface surrounding the sound entrance aperture of the assistive hearing device. A removable strip can be removably attached to the adhesive material bonded to the first adhesive containing portion. The removable strip covers the adhesive material until it becomes desirable to attach the assistive hearing device to the mobile phone. The assistive hearing device may be connected to a strap, which straps the assistive hearing device to the mobile device. The assistive hearing device also may be connected to the mobile device by an elastic/silicone band or a band securable by hook and loop that fastens at its ends. The band may be adjusted to fit a variety of phone sizes and shapes.
The assistive hearing device of the present invention can be constructed from a variety of materials, including but not limited to plastic, metallic, compound materials, etc. Furthermore, the assistive hearing device may be constructed into a variety of shapes and sizes to account for the distance between the phone speaker and the input/microphone of the hearing device.
