Hearing Assistance Basics

An Introduction to Hearing Assistance Systems

Why should a hearing impairment keep anyone from enjoying the message or music in your services or programs? With a hearing assistance or assistive listening system people with a hearing impairment won’t have to miss a thing.

A basic hearing enhancement system typically includes a transmitter, receivers, and some form of earpiece or earphone for the listeners. The transmitter easily connects to an auxiliary output on your mixing console and transmits the signal to each of the individual receivers. The person using the receiver can adjust the volume to his or her liking and can place the receiver in a pocket or purse — anywhere nearby — or clip it to a belt.

The most common methods of transmission used with these types of systems are either radio frequency (RF) or infrared (IR). RF systems are available on a series of FM frequencies chosen by the FCC. These frequencies do not overlap with any other common radio transmission, isolating the FM hearing enhancement systems from any unwanted radio signals. Since RF signals can be transmitted through walls and other obstacles, RF system users are able to hear program material throughout a building, whether in the sanctuary, hallway, or some other location.

By contrast, an IR receiver must generally be used within the line of sight of an IR transmitter. Typically more costly than RF systems, IR systems allow a greater frequency response and higher fidelity. Additionally, IR systems usually deliver a better signal-to-noise ratio than RF systems.

Hearing assistance systems can also be used to reach those who require language translation.

A language translation system can be set up by using a microphone and headset which allow the translator to hear the words spoken through your sound system, then send a translation to the transmitter of the hearing enhancement system. Your translation system can be set up on a channel specifically for those needing the translation — separate from the main hearing enhancement system.

Optional earpieces include single and dual earphones or ear buds, and headset earphones. Neck coil loops and ear speakers let audio be heard without being set in the listener’s ear, so they can be used by someone with a hearing aid.
