Telecoil Definition

What is a telecoil? A Telecoil is defined as a tiny RFID receiver antenna, which receives magnetic information.

Telecoils have multiples turns of copper wire wrapped around a magnetic core. The telecoil provides high sensitivity in a very low frequency range by using more than 10,000 wraps of copper wire. This means that the diameter of the copper wire used must be in the range of 12 to 20 micron, which is approximatley the diameter of a human hair.

Telecoils in Hearing Aids

Due to its miniature size, the telecoil is mostly used in hearing aid system where the receiver is situated within the hearing aid.

How does a telecoil work for hearing aid? The telecoil is a small receiver transponder placed inside the hearing aids that detects and converts magnetic energy from the hearing aid “loop system” into electrical energy, similar to the way a microphone converts acoustic energy into electrical energy. Then the telecoil converts the signal collected from the loop system into a sound signal that you hear.

Using a hearing aid with a Telecoil and Loop System you can get amplified sounds delivered directly into your hearing aids. So, no matter where you are in the church, classroom, or theater, you automatically have the best seat in the house.
