Abstract
A directional microphone assembly in which an electroacoustic transducer housed in a capsule, having a directional response characteristic, is mounted in the assembly housing and surrounded by an acoustically transparent foam covering. As a result acoustic waves reflected off surfaces of the housing are dispersed so as to minimize the effect of the surfaces on the directional response characteristic.
