The Williams Sound small room loop system readily accommodates individuals with hearing difficulties. In this example, the loop system picks up the sound from a TV program from a direct source connection like a cable box.  (The supplied external microphone could also be used by attaching it to the TV speaker).  The amplifier transmits this audio directly and clearly to a listener’s hearing aid equipped with a T-coil. The listener's hearing aid can receive the audio when they are within the perimeter of the loop wire.
