Propagation of Ultrasound in Solutions of Biological Substances
The values of ultrasound velocity and absorption coefficient in solutions are defined by different molecular interactions. There is a large amount of literature on the investigation of molecular characteristics of solutions of biological substances by ultrasonic measurements. The dominant part of this paper is devoted to the measurements of the frequency dependences of ultrasound absorption and the investigation of fast relaxation processes. Substantially fewer works are related to the study of solutions by ultrasound velocity measurements. But such a proportion is a result of the absence of adequate velocity measurement methods and not due to the fact that the absorption coefficient is more informative than the velocity of ultrasound about the characteristics of a solution.
