This paper describes acoustic methods of non-destructive testing to determine the concentration of components (matrix and reinforcing material) in a two-component heterogeneous composite material. The peculiarity of acoustic methods of non-destructive testing is cheapness, efficiency, and the possibility of automation of measurements. Acoustic measurements are a very important method and an example of control methods without disturbing the composition of a heterogeneous medium. All input data is entered through a part of the workspace, calculations are performed by pressing the appropriate command buttons and the desired output data is found. Based on the revealed data, it is possible to build software models that allow calculating wave phenomena in inhomogeneous media with various examples, plotting the calculation of true low frequencies, and choosing an effective method using heterogeneous concentrates
