What is hearing aid loop?
Last Updated: Feb 20th, 2019
A hearing loop is a sound system for hearing aids. Another name of the hearing loop is an audio induction loop.
A Hearing Aid Loop consists of a microphone, an amplifier and a coil of wire. It is placed around the room. Sound waves are changed into the electric current, amplified and then sent through the coil which emits a magnetic environment in the room.
The magnetic environment is picked up by the “T” switch of the hearing aid, amplified and converted back into the sound. Hearing Aid Loop is also known as the Audio Frequency Induction Loop System (AFILS).
Telecoil or T loop is a specialized circuit which is to be kept within hearing aids having small coiling wire.
It is designed in such a manner that it can pick up magnetic signals versus acoustic signals picked up by the hearing aid microphone.
When a telecoil start working or we can say that telecoil is activated the hearing aid’s normal microphone is turned off.
This telecoil just picks up magnetic inputs. The hearing aid then converts these magnetic signal to sound. Further which are amplified by the hearing aid like any other sound is. A most important benefit is no other sounds in the surrounding are amplified, thus the hearing aid user can just focus on the amplification of magnetic inputs.
