Telecoils or t-coils expand the function of hearing aids. It’s a copper wire that is coiled in the the hearing aid. It works with telephones, looped public places, and assistive living devices. A looped public place uses a magnetic wire than runs in the walls or under the carpet to connect you to their listening systems. Such public places might be movie theaters, houses of worship, or schools.
The function of a telecoil
Most often, a hearing aid contains a microphone, amplifier, and receiver. The microphone listens to the environment, the amplifier processes the signal from the microphone, and the receiver presents the signal to the ear. An optional piece, the telecoil is in many hearing aids. For example, the Starkey Muse iQ Rechargeable has this technology. The telecoil listens instead of the microphone and is sensitive to magnets. It allows you to connect to phones, larger public places, and assistive living devices.
A telecoil and telephone
You can push a button, turn on a switch, or use a remote to access a telecoil using a specific memory function. Such a manual operation is called Manual Telecloil. Some hearing aids have an automatic function called Auto Coil.
Not all phones contain a telecoil. Cell phones with a “T-Rating” have a telecoil. For handsets and landlines, check for a sign that the handset is compatible with a telecoil. If you wish to connect your telecoil with a loop system, make sure your hearing instrument specialist knows.
