Abstract
The present report describes the measurements carried out on two treatment heads manufactured by BAC Srl for the ultrasonic equipment for physiotherapy/aesthetic treatments "SIRIO". The scope is to characterize the ultrasound beam generated by the two transducers. The measurements were realized in the Underwater Acoustics Laboratory of the Institute of Acoustics and Sensors "O.

The measurements were commissioned by the manufacturer, BAC Srl, Figline Valdarno, Florence, Italy.The report deals with the hydrophone measurements requested for the two treatment heads of the SIRIO equipment, both operating at the frequency 38 kHz:1.
