The article describes the experimental setup is designed to test the ability of manage the ultrasonic beam as it passes through the layered media. In this paper we consider a methodology of research, justified the choice of material for the simulation layers of biological tissues. The article describes the characteristics of the developed installation and positioning methods acoustic transducer. Solution of the experimental research allowed us to estimate the deviation of the "maximum" acoustic pressure (in the transverse distribution) by passing through the layered media and to determine the influence of the sound velocity in the transition layer on the distribution of acoustic energy in the region of space.
