How does a hearing loop work? A hearing loop system consists of a microphone or audio source to pick up spoken word, an amplifier which processes the signal, and a copper wire “loop” that sends the audio directly to the hearing aid or cochlear implant using a magnetic signal.
The copper wire loop is placed around the perimeter of the area to act as an antenna that sends a magnetic signal to the hearing aid. This signal allows users to hear any audio clearly without amplifying background noise. A loop can also be installed in smaller areas, such as an pharmacy counter for one on one conversations.
A hearing loop works with a hearing device that has a telecoil or t-coil. When a hearing loop is used with the assistive hearing device, the hearing loop is able to cut out confusing background noise. This would be impossible without a hearing loop because an assistive hearing device elevates ALL sound, not just the sound you want to hear.
Here is a video from Contacta, our assistive listening device dealer. The United States statistics may be different, but the loop information is the same.
