On Electronic Formation of Directivity Characteristics of a Microphone

要約

A directional microphone composed of two nondirectional diaphragm cases and an electronic module for formation of directivity characteristics (DCs), i.e., an "octad", a cardioid, etc., is investigated. Analytical expressions for frequency response characteristics (FRCs) and the microphone DCs are obtained. The need for frequency adjustment of FRCs is justified; methods of testing the DC formation module, not requiring free-field conditions are proposed. Results of experimental investigations of the module of formation of DC of the multipattern microphone are presented.
