The measurements of acoustic power introduced into gas medium by the ultrasonic apparatuses with the disk-type radiators

The article presents the results of studies aimed at the definition of acoustic energy value introduced into gas medium by ultrasonic apparatuses with the disk radiators measuring consumed electric power of the ultrasonic devices at different levels of gas medium static pressure in a closed volume. It is shown, that developed procedure allows obtaining real values of radiated acoustic power as opposed to the methods based on the measurements of acoustic pressure level in single pointes of insonified technological medium.
