Telecoil hearing aid

A wonderful feature available on many hearing aids is called the "telecoil". It is also called a "t-switch" or "t-coil". It is nothing more than a small spiral of wire around a core that will induce an electric current in the coil when it is in the presence of a changing magnetic field.

A telecoil can therefore be an alternative or additional input device for a hearing aid. Normally, a hearing aid "listens" with its microphone and then amplifies what it "hears". But with a telecoil used as the input source instead of (or in addition to) the microphone, the hearing aid can "hear" a magnetic signal representing sound. If you use a telecoil for hearing aids, you often understand the TV programme much better.

What can I do with a loop hearing aid?

On hearing aids and CIs equipped with a telecoil, the wearer must "turn on" or "switch to" telecoil mode by moving a small switch (on older models) to the "T" position, or by switching to a programming mode (by pressing a button on the device at ear level or on a remote control) that is set to use the telecoil as an input source instead of or in addition to the microphones.

A loop hearing aid is the way to enjoy listening to TV with minimal listening effort.
