AB  - The mathematical model and theoretical analysis of the work of the directional microphone which con-sists of the interference tube and pressure - gradient capsule are presented. The analytical expressions for angular dependence of the geometrical path length and directional characteristic are received. The physical reasons of the difference between polar pattern of such microphones and separate capsule in the low frequencies range are ascertain. The dependence of the required rear aperture acoustic resistance on the acoustic antenna length is shown. The reasons of the polar pattern axis asymmetry are analyzed. The practical recommendations for such microphones designing are given.
