Although most types of hearing aids work quite well for small settings when the person talking is nearby, it can be harder to hear when sound comes through a speaker, into the hearing aid, and then comes out the other speaker in the wearer’s ear. This is why many hearing aids have a telecoil, which is a small piece of technology that allows the wearer to piggyback on a speaker’s system to get the sounds directly in the hearing aid. By bypassing one set of speakers and microphones, it makes speech much clearer, especially in large and noisy environments.
Hearing aids with telecoil technology are equipped with a switch that the wearer needs to activate to start receiving the electromagnetic signal from the nearby device. The switch turns off the hearing aid’s microphone and switches to amplifying the signal received from the telephone, sound system, or other device emitting an electromagnetic signal. By law, all telephones work with telecoils, so this is a quick way to reduce the amount of feedback hearing aid wearers get by using the hearing aid on its normal setting while on the phone.
