Selection of the commutator circuit in a single-vibrator sound locator

Abstract
The use of single-vibrator acoustic systems in sounders for surveying inaccessible mine workings is dictated by the desire to improve their technical and economic characteristics. It is obvious that combining in one electroacoustic transducer the functions of the emitter and receiver of acoustic signals allows to increase the accuracy of measurements, simplify the design, reduce the size and weight, as well as reduce the cost of the acoustic system.
