Abstract
One of the ways to reduce the cost of surveyor sounders using a single electroacoustic transducer as a sound emitter and receiver. In sounders with separate receiver and transmitter, the axes of directional characteristics of the transducers are usually separated by some distance, which makes it difficult to receive signals reflected from the near parts of the locatable surface. This disadvantage is completely eliminated in single-vibrator locators, since the directivity characteristics of the same electroacoustic transducer in the modes of emission and reception coincide.
