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.

This paper shows the results of the experimental research the passage of the ultrasonic beam through modifiable layered structure in order to obtain data on changes in levels of pressure in the front slice of the acoustic field. This paper presents the spatial distribution characteristics of the acoustic field after passing the various layers in the liquid. Celebrated not only offset the propagation path, but also change the chart pressure in the front slice on the amplitude level , the width of the chart, the position of the lateral lobe and its amplitude.
