An induction loop system is a loop of wire that is installed around the perimeter of a listening area and it emits a magnetic field. The loop receives its input signal from a sound source such as the public address system in a theatre, church or other public venue. Most modern hearing aids are compatible with loop systems. Compatible aids feature a ‘T’ switch. With the switch set to the ‘T’ position the wearer can hear the sound source directly via the loop, bypassing the hearing aids microphone.

Where do I find loop systems?

Venues that provide a loop system display the “Ear” symbol. Many public buildings are wired with loop systems. Sometimes loops systems are not turned on or are broken, so you must ask if you are unsure. If you are not certain, try switching your aid to the ‘T’ position. If your hearing improves, it is picking up the loop system. If you hear a buzzing sound or a wind-like noise, then there is no loop system working.

You will find loop systems in many public buildings and on some telephones. Some people have them installed in their own homes. Some telephones will often specify it is “Hearing Aid compatible,” which indicates it will receive the loop signal.

Is my hearing aid compatible with a loop system?

Most modern hearing aids are compatible with loop systems, or can be made compatible. You will need a ‘T’ switch option on your hearing aid. If you are not sure ask the staff at Hearing Consultants.
