Abstract
A modular assistive listening system is disclosed that employs a hand-held switching/control module to select one or more of the signals transmitted from a plurality of remote input modules. The selected signal is then transmitted to an earphone module that converts the selected signal to audible sound. The hand-held switching/control module permits a hearing impaired person to easily select desire input modules while permitting unrestricted movement by the use of wireless transmission from the switching/control module to the earphone module.
