Abstract:In this work it is shown that a change in attenuation coefficient of ultrasound signal
depends on a nature of thermodynamic process when air-coupled ultrasonic
measurements are carried out in closed systems. Therefore, for the air-coupled ultrasonic
measurements in such systems, it is necessary to choose measurement system
parameters in advance according to the thermodynamic process is taking place in the
systems.
