How the Neckloop Works
The Neckloop is a miniature audio induction loop worn around a users neck. I*t uses invisible magnetic energy to transfer the electrical signal from a sound source (Pocketalker, FM Receiver, etc.) directly into a hearing aid equipped with a T-coil (telephone coil)
When the audio signal from an earphone or loudspeaker jack is fed into the Neckloop, a magnetic field is created around the Neckloop wire and users head. As the audio signal varies, the magnetic field also varies. The varying magnetic field induces a small electrical current in the hearing aid T-coil corresponding to the original signal. The T-coils signal is then amplified and converted to sound by the hearing aid.
