A Telecoil (T-Coil) is a copper coil — built into a hearing aid, cochlear implant or loop receiver — that functions as a wireless antenna capable of picking up an audio signal generated by an audio induction loop amplifier. The audio connection made improves the effectiveness of hearing devices (all brands) which are tuned to resolve individual patterns of hearing loss.  Without the need for any additional equipment, crystal clear sound is delivered — in spite of background noise and acoustic interference that distorts sounds when only a hearing aid or implant is in use.

A Telecoil may be activated manually or set to automatically switch on in the presence of a hearing loop field. All landline phones are designed, by law, to be used with a telecoil.

Hearing Loops:  A Top Choice for Hearing Accommodation

According to the Hearing Loss Association of American (HLAA), “hearing loops provide the greatest benefits to people who rely on assistive listening systems, and to venues required by the ADA to provide hearing accommodation.”

Loops installed to the IEC 60118-4 standard (International Electrotechnical Commission) reliably deliver the cleanest sound to people with hearing loss—even to those with severe to profound hearing loss. Because of this, hearing loops are becoming the foundation for hearing-friendly, inclusive communities throughout the United States.

The Most User-Friendly ALS (Assistive Listening System) 

According to Juliëtte Sterkens, AuD, and Loop Advocate for the HLAA:

“While hearing aids have come a long way in the last decade, they do not give you normal hearing and most users report that hearing over distance, in reverberation and background noise (such as houses of worship, meeting rooms, theaters, lecture halls, pharmacy service counters and ticket windows) is still difficult regardsless of the level of technology inside the instruments. That is where the ADA (Americans with Disability Act) mandates the provision of assistive listening systems (or ALS for short). The most user-friendly ALS –  and one that is increasingly finding its way in public venues around the country – is hearing loop technology. But, in order to benefit from a hearing loop you need a telecoil either built inside the hearing aid or in the hearing aid streamer or remote control.
