Compact and easy to use, the Williams Sound Small Room Loop System readily accommodates individuals with hearing difficulties. The small room loop system picks up the sound of a speaker's voice (or other source like a television) from a microphone (or wired connection) and transmits the sound directly and clearly to a listener’s hearing aid equipped with a T-coil.  The listener can pick up the audio when they are within the loop. This technology allows background noise to be eliminated while listening to a speaker's voice or audio program.
