Wireless Communication Technology

Wireless Communication Technology for Persons with Hearing Loss

Wireless communication technology is very common today for a multitude of applications and situations all over the world, whenever communication is the focus of interest. Some examples of the use of wireless communication technology are cable-free telephones, walky-talkies, and baby monitoring systems.

Why Wireless Communication Is Important

Even with the best hearing instruments, most hearing-impaired people notice that they have difficulty hearing in certain situations such as using a telephone, watching television, during a business meeting, or in a restaurant. Using a wireless communication system (FM system) makes communication in all these difficult situations much easier with direct input to the hearing aid.

Today there are three different types of wireless communication systems available to our patients with hearing loss. We can help determine which wireless system would be most appropriate for each patient.


Most major hearing instrument manufacturers now allow for Bluetooth reception in some of their hearing aids. This means that your hearing aids may communicate directly with another Bluetooth device such as a cell phone, iPod or TV. If your hearing aid is Bluetooth, you must purchase a separate “streamer,” usually worn around the neck, that directs the signal directly to your hearing aid.

FM Systems

A wireless FM system consists of a transmitter, which picks up a signal from a distance and sends it via radio waves directly to a tiny radio (FM) receiver, which is usually connected to the personal hearing aid. FM systems are very useful to improve listening from a distance or in background noise. There is much more information at:


Loop Systems

A loop system works with the magnetic T-coil (telephone switch) in your personal hearing aid. Loop systems may be used in small and large areas (such as home TV, churches, and auditoriums). Loop systems create a magnetic field in a designated space, and when the hearing aid is in the “T” position, the patient can receive direct input into their personal hearing aid with no background noise.
