Abstract
A wireless listening system includes a base operable to receive an electrical signal corresponding to an audio signal, including the ring of an incoming telephone call, up-convert the audio signal to an infrared signal, and transmit the infrared audio signal wirelessly therefrom, and a wireless headset operable to selectably receive either the infrared audio signal transmitted by the base, or an infrared signal corresponding to an audio signal transmitted by a public address system, down-convert the received signal back into the audio signal, and audibly reproduce the audio signal to a wearer of the headset. The system enables a hearing impaired listeners to enjoy their favorite audio programs without disturbing nearby persons with normal hearing and without missing an incoming telephone call, and is also compatible with public IR PA systems currently used to assist the hearing impaired community.
