The telecoil works by receiving an electromagnetic signal from the hearing loop and then turning it back into sound within the hearing aid or cochlear implant. It also is used with a variety of other assistive listening devices, such as hearing loop (or induction loop) systems, FM systems, infrared systems, and personal amplifiers. It was originally designed to make sounds clearer to a listener over the telephone.

For those who don’t have hearing aids with embedded telecoils, portable loop receivers are also available.Ī telecoil, also called a t-coil, is a coil of wire that is installed inside many hearing aids and cochlear implants to act as a miniature wireless receiver.
A hearing loop can be connected to a public address system, a television, or any other audio source. Some loop systems are portable, making it possible for people with hearing loss to improve their listening environments, as needed, as they proceed with their daily activities. Because the sound is picked up directly by the receiver, the sound is much clearer, without as much of the competing background noise associated with many listening environments. To pick up the signal, a listener must be wearing the receiver and be within or near the loop.
A receiver worn in the ears or as a headsetĪmplified sound travels through the loop and creates an electromagnetic field that is picked up directly by a hearing loop receiver or a telecoil (see sidebar), a miniature wireless receiver that is built into many hearing aids and cochlear implants.

A sound source, such as a public address system, microphone, or home TV or telephone. A hearing loop system involves four parts: Hearing loop (or induction loop) systems use electromagnetic energy to transmit sound. This logo informs people that a public area is looped. ALD systems for large facilities include hearing loop systems, frequency-modulated (FM) systems, and infrared systems. All can be used with or without hearing aids or a cochlear implant. Other types are intended for personal use in small settings and for one-on-one conversations. Some are designed for large facilities such as classrooms, theaters, places of worship, and airports. Several types of ALDs are available to improve sound transmission for people with hearing loss. What types of assistive listening devices are available? Alerting devices connect to a doorbell, telephone, or alarm that emits a loud sound or blinking light to let someone with hearing loss know that an event is taking place. These devices can range from a simple picture board to a computer program that synthesizes speech from text. Augmentative and alternative communication (AAC) devices help people with communication disorders to express themselves. ALDs can be used with a hearing aid or cochlear implant to help a wearer hear certain sounds better. Assistive listening devices (ALDs) help amplify the sounds you want to hear, especially where there’s a lot of background noise. Health professionals use a variety of names to describe assistive devices: What types of assistive devices are available? With the development of digital and wireless technologies, more and more devices are becoming available to help people with hearing, voice, speech, and language disorders communicate more meaningfully and participate more fully in their daily lives. These terms often refer to devices that help a person to hear and understand what is being said more clearly or to express thoughts more easily. 
The terms assistive device or assistive technology can refer to any device that helps a person with hearing loss or a voice, speech, or language disorder to communicate.
