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.
