Abstract
A microphone construction for use in a hearing aid wherein a faceplate separates a switching mechanism from a microphone having first and second acoustic ports. The first and second acoustic ports are placed into acoustic relationships with first and second acoustic opening within the faceplate by first and second acoustic passages, respectively. The switching mechanism is positionable between a first position wherein the first and second acoustic ports are in an acoustically receptive state and a second position wherein either the first or second acoustic port is in an acoustically receptive state and the other acoustic port is in an acoustically unreceptive state.
