The Invisible Solution for 48 Million Americans

Switch Hearing Aid to T-CoilHearing aids and cochlear implants amplify sound and work well in small, quiet environments for one-to-one conversations. In larger, noisy spaces, and when ALL sounds are amplified by a hearing device, it becomes even more difficult to hear and understand clearly what is being spoken. The international logo for T-Coil users (a blue sign with an ear and the letter "T") lets people know that if they select the "T-coil" setting on their device, crystal clear sound will be delivered directly to their hearing device.

The dramatic benefits of hearing loops have been documented in two studies. A survey in 2014 asked 866 people to rate the performance of their hearing aids or cochlear implants using a 10-point scale (Hear Rev, 2014). The average response was 4.9 in a non-looped setting and 8.7 in a looped environment. A 2016 study by Faivre found that hearing loops greatly improved speech understanding and sound quality, and reduced listening effort (Hear Rev, 2016).

How can a hearing loop deliver such dramatic improvements? Simple. In a hearing loop, the microphone of the PA system is the microphone to the hearing aid. The distance and reverberation limitations of hearing aid microphones are overcome in a loop. Instead of acoustically transmitting sound, this setup transfers sound via a magnetic field. Those in a loop hear the cleanest and purest sound possible, often at signal-to-noise ratios that enable even those with severe and profound hearing loss to understand speech.

The hearing loop movement is spreading across the United States, with new equipment vendors and dozens of trained installers. There are thousands of installed hearing loops across the country, from small areas (i.e., all new New York City taxis), to medium-sized worship places and auditoriums, and to sizable airports and stadiums (including the Michigan State Univeristy's basketball arena). This increased hearing aid functionality bodes well both for hearing care providers and those we serve.
