Loop systems, sometimes called an induction loop system or simply a hearing loop, use a pre-installed telecoil (or "t-coil") in hearing aids and cochlear implants to transmit sound directly from a microphone, worn by the speaker, to your hearing aids. They are used in places of worship (e.g. churches), auditoriums, and theatres.

Loop systems

FM Systems are most often used in schools and use FM radio signals. FM systems are used with a boot (a small device attached to the hearings aids) or a receiver worn around the neck where sound from a microphone, worn by the teacher, is transmitted directly to the student's hearing aids using radio waves. 

FM Systems

Infrared systems function similar to loop systems but are often used in situations where privacy and confidentiality are needed, such as in courtrooms and banks. Infrared systems use light to transmit signals, which cannot be transferred through walls, providing an additional layer of privacy.

Public-use ALDs are systems that are designed to be used on public properties including places of worship, courtrooms, theatres, and schools.

Assistive listening devices (ALDs) are devices that can be used along with your hearing aids to enhance your listening experience and provide extra help in challenging listening situations.

- Enhance hearing and sound quality in noisy or challenging listening environments
- Offer substantial hearing benefits when used with your hearing aids or without.

Public-use Assistive Listening Devices (ALDs)

There are many different types of assistive listening devices available for private use that can be beneficial to use in certain listening situations to overcome background noise and gain a clearer sound.
