Abstract
Disclosed is a convenient way of mounting the microphone array and associated electronics of a hearing aid on the person, and providing a convenient wireless means for delivering the microphone signals to the ear, and providing a signal processing technique that yields sharp directivity at audio frequencies. The wearer positions her/his body to receive the desired signal and to attenuate surrounding background noise and multipath interference.
