Abstract
A bilateral hearing instrument incorporates first and second units which could, for example, be worn by an individual having hearing deficiencies in both ears. One unit includes an audio input transducer coupled to a transceiver. The second unit includes a second audio input transducer coupled to a second transceiver which is coupled, wirelessly, to the first transceiver. An output of the second transceiver is coupled to an input port of a signal processor. A second input to the signal processor comes from the second audio input transducer. One output from the signal processor Is transmitted Tirelessly to the first unit for presentation to one ear of the user. The other output of the processor is coupled to an output transducer for the user's second ear. A single signal processor generates representations of audio output signals for both of the user's ears.
