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.
