ABSTRACT:
A unidirectional microphone element can be embedded within an object and be made flush to the object's surface yet retain its directional discrimination characteristic. Acoustic waveguides transmit acoustic input signals from acoustic ports to the front and rear input ports of the microphone element while also providing intelligibility-enhancing frequency response shaping. The housing wherein the microphone element is mounted acoustically isolates the front and rear input ports of the microphone element.
