ABSTRACT:
A unidirectional microphone assembly for receiving sound within a range of sound frequencies is disclosed. The microphone assembly comprises a housing formed of a sound absorbing material. The housing has an outer surface, and a bore extending inwardly along a bore axis from the outer surface to form a chamber within the housing. The microphone assembly further comprises a directional microphone having an axis of maximum reception. The microphone is disposed within the chamber and positioned with its axis of maximum reception directed outwardly substantially along the bore axis.
