A hearing loop provides a wireless signal, called an induction signal to be sent out via a copper wire that is picked up by a persons’ hearing aid’s t-coil. The loop system consists of a microphone that a person talks into and or a tv signal, a play or anything else going through a audio system, which is transferred to an ampliﬁer that processes the signal and sends it to the coper wire, a wire placed around the perimeter of an area. Hence the loop!
Hearing loop systems provide the best listener experience of any hearing solution – a direct connection between hearing aids and the sound source. It can be comparable to an FM system with a neck loop.
A hearing loop also called an induction loop, provides the lowest maintenance cost and lowest cost per user of any advanced hearing solution. This is because once the coper wire is placed around the room it is set for life of that room or until it is removed. The microphone and the amplifier comes with warranties and may need to be replaced on occasion. The patient is then responsible for their own hearing aid and t-coil system.
Most hearing aids (65%) come with T-coil. The reason they may not is because the person chose a hearing aid that is too small and the t-coil was left out to keep the hearing aid small. It will become MN state law in the near future that patients are told when they are not getting a t-coil in their own personal hearing aid.
The person must push a button to activate the t-coil to assess the signal from the microphone in the hearing loop. They must also be in-side the loop and not on the other side of the loop.
A hearing loop helps persons hear sounds from an audio system directly and clearly in their hearing aids, because it reduces or cuts out background noise. Not only does it go directly to the ear, it is amplified according the prescription inside the hearing aid for that person’s individual loss.

Watch some videos from Midwest Hearing loops on hearing loops.
This is an installation group that has shared videos of Loops they have done.
