Examining the Efficacy of Hearing Loops

Hearing loops are designed to ramp up the listening experience for wearers of hearing aids. This is due to the technology that allows cables and telecoils to work in tandem to pick up on conversations without the added distraction of background noise. Two centuries ago, everyone was excited about the “state of the art” hearing trumpets, but today, it’s clear just how far the hearing impaired community has come. Present in a growing number of conference rooms, schools, churches, businesses and public spots, those with hearing impairments can now enjoy a higher level of hearing. This is great news for the millions of Americans who suffer from some degree of hearing loss. Although hearing aids on their own do an adequate job of amplifying sound individually, they’re not as efficient at filtering out background sound in crowded public areas or within meetings.

What Are Hearing Loops?

This is a matter of fact technology involving cables that are laced through a room with signals that are detected and interpreted by individual hearing aids. Combining the technologies from hearing aids and that of cables, these loops are made possible by a cable running throughout a building or a room. They work in parallel with the hearing aids worn by hearing impaired participants, resulting in a crisper listening experience.

A Closer Look

The result of the hearing loop is an increased chance of hearing conversations in crowded, noisy situations. Even microphones can be brought into the equation for better performance. A t-switch present in most modern day hearing aids and cochlear implants is a big part of the telecoil technology that makes this all possible. The switch, able to detect the electromagnetic sounds funneling through the hearing loop, gives the user a better chance of detecting sounds more clearly without background distraction.
Circling the room, a hearing loop wire transmits ambient sound via electromagnetic signals that are detected by telecoil, originally used in assisting handset telephones retain their ranges and signals while disconnected from the base.

Implementation

The effectiveness of hearing loops has had a clear advantage to the hearing impaired community. You’ll now see more and more hearing loops available in city halls, conference rooms and in public transportation areas like airports. This is because more cities and nations are implementing laws that require their use in certain public spots.
