Hearing Aid With Induction Loops (Telecoils)

Almost 90 percent of hearing aids has built-in induction coil for transmitting the sound directly into the hearing aid. Telecoils, or t-coils, are small copper wires discreetly coiled inside hearing aids. They can receive electromagnetic signals from various sources and are generally activated easily with the touch of a button. Telecoils work in pairs with a hearing loop system in many public venues worldwide to assist those with hearing loss.

This inductive loop system provides a magnetic, wireless signal that is picked up by hearing devices with telecoils. When hearing aid users are inside the loop, and their t-coil setting is activated, any conversation being broadcast on the facility’s audio system — i.e., a church sermon, classroom lecture, or stage performance — is sent directly to the telecoil in their hearing device. In places where hearing loop systems are installed, you can usually find this sign:

To use telecoil, you must switch your hearing aid into T possition.

Not all hearing aids have a built-in telecoil; some manufacturers remove them to make hearing aid smaller. You need to ask your hearing healthcare practitioner if your hearing aid supports this technology or find a specification of your model on the internet. Manufacturers usually indicate on their websites which hearing aid model has this function.
