Hearing aids have been the traditional solution for hearing loss and while they do a good job of allowing the hard of hearing listen to a single sound source, they do not have the same affect in congregate situations encountered in assembly halls or meeting rooms.
Ambient noise and multiple sound sources create a major challenge for senior citizens with hearing aids in discerning what they want to listen to from what they don’t. This has been termed the “Cocktail Party Effect”, which is especially disconcerting for those with dementia or Alzheimer’s. A Hearing Aid Loop transmits the desired sound source directly to the hearing aid, eliminating all the background noise and the confusion it causes.
A Hearing Aid Loop is a low voltage wire antenna connected to a Hearing Aid Loop Amplifier that delivers an audio signal for transmission through the antenna directly to T-Coil-equipped hearing aids without background noise or interference.
To put it more simply, a hearing aid loop is a loop of wire placed around the outside of a room (usually hidden under carpet or molding) and connected to an amplifier, which is connected to multiple audio sources. When this loop is powered, the selected source is "broadcast" inside the loop and is "received" directly by a T-Coil equipped hearing aid.
A T-Coil is a small coil of wire inside a hearing aid which uses no electricity therefore doesn't affect the battery life of the hearing aid. The sound is mixed and adjusted by the hearing aid to compensate for the user’s specific degree of hearing loss. T-Coils are in over 75% of hearing aids and in most cochlear implants.
With a loop system, T-Coil equipped hearing aid/implant users enjoy clear sound without wearing another device that needs charging or batteries or headphones.
Loops can make a profound difference for the hard of hearing anywhere that sound or announcements are broadcast. This includes presentations, religious services, live and recorded music, classes, group activities, movies and cable television.
