A communications earpiece comprises an ear canal tube sized for positioning in an ear canal of a user so that the ear canal is at least partially open for directly receiving ambient sounds. A sound processor amplifies the received ambient sounds to produce a processed analog signal. The processed analog signal is then converted into digital signals and transmitted to a remote unit via a wireless link. The earpiece also receives signals from the remote unit which are then processed and applied to a speaker in the earpiece.Field of SearchHook over earEar insert Specified casing or housing Spectacle HEARING AIDS, ELECTRICAL Frequency transposition Wideband gain control Testing of hearing aids Programming interface circuitry Remote control, wireless, or alarm Spectral control Power supply or programming interface terminals Headphone Ear insert or bone conduction Hook over ear or spectacle INCLUDING AID FOR HANDICAPPED USER (E.G., VISUAL, TACTILE, HEARING AID COUPLING) Body supported (e.g., headgear) | |
