The Americans with Disabilities Act and other efforts have made the world accessible to all people. However, in some ways that access is incomplete. For millions of Americans using hearing assistive devices, the ability to hear in public facilities is limited. Yet sounds can be made clear by installing a simple and cost effective technology in public buildings and facilities – the induction loop.
The induction loop is to hearing aids, what Wi-Fi is to laptops. Looping allows hearing assistive devices to serve as wireless loudspeakers, delivering clear, sharp, customized sound right from inside the ears. It can be adapted to use in large public spaces, such as airports and auditoriums. But it can just as easily be installed in churches, drive-up business windows and even into a single room at home so the TV or stereo sound becomes a broadcast going directly through the hearing assistive device.
Looping is a cost effective way to make more precise hearing available. The value of also having an area looped in the case of emergency situations is priceless.
Looping uses two separate technologies: the induction loop and its related components, and the hearing assistive device that has a tele or t-coil.
The induction loop is usually a high quality single strand copper wire and an amplifier. The size of the space to be looped determines the size and length of the wire loop, as well as the power level of the amplifier.
The public address system, TV or other broadcast source is attached to the looping system amplifier. The looping system amplifier sends the broadcast signal through the looping wire creating a magnetic energy field that can be picked up by tele or t-coils.
Also referred to as a “t-switch” or “t-coil”, these are tiny coils of wire that when in the presence of a changing magnetic field – such as those created by an induction loop, create a small electric current, which is transmitted as sound directly to the listener through the speaker in the hearing assistive device. This system bypasses the microphone and amplification function of the device, allowing listeners to hear a broadcast media without hearing the background noise and other competing sounds.
There are three ways you can make A Sound Investment:
One of the best ways is to form a speakers group that gives presentations to churches, synagogues, service clubs and business groups.
Sertoma has prepared a presentation specifically for volunteers for other community members. If after these presentations or in response to a PSA effort, additional technical information or support about looping is required, it is available through Sertoma and other participating organizations. You could also consider working with the local media to develop public service announcements.
There have already been dozens of successful citizen led efforts to loop facilities. Raise funds to loop a local facility that otherwise would not be. Public facilities, like airports, could combine fundraising from direct support and community advocacy. Raise funds to loop a low-income individual’s home with a home-based system.
The primary benefit is you can become a leader on an important community issue. If you adopt a project or assist with another organization’s project, you will build new volunteer relationships. There is great value in building relationships with other organizations and groups, such as the local American League of Hard of Hearing or the audiology and medical communities.

The Lexington Medical Center of Lexington, South Carolina, teamed up with the Lexington Sertoma Club to host a special seminar at the hospital, which educated and inspired individuals to take an interest and initiative in pursuing hearing health. For Sertoma member, Buzz Lewis (right) the event proved to be life changing.
The Norfolk Sertoma Club of Norfolk, Virginia, donated $150,000 to Eastern Virginia Medical School (EVMS) to fund a new state of the art temporal bone laboratory. This new lab has enabled both medical professionals and students to research, learn and practice various techniques and procedures pertaining to the brain and hearing health
The Mansfield Sertoma Club and Delta Zeta Sorority planned a special field trip for some of the special education, Deaf and Hard of Hearing students attending the Mansfield public schools. The field trip took place at the Ohio Senate (photographed) as well as the Ohio House of Representatives and Ohio History Museum.
