PROBLEM TO BE SOLVED: To sensuously alarm an operator about irradiating ultrasonic and the current ultrasonic level. SOLUTION: When an operator indicates through a console 1 that the starting of ultrasonic irradiation, a controller 2 controls to irradiate ultrasonic to the affected part of patient through an actuator 6 and drives to oscillate an oscillator 8. The oscillator 8 supplies the oscillation output to a variable gain amplifier 9. An output level monitor 5 detects the ultrasonic level of actuator 6, which is controlled to drive with the controller 2, and supplies the detected output to the variable gain amplifier 9. The variable gain amplifier 9 amplifies the oscillation output with the gain that is according to the detected output from the output level monitor 5 and supplies the amplified output to a speaker part 12. Then it is possible to obtain the volume of acoustic output according to the current ultrasonic level through the speaker part 12, and it is possible for the person who is operated to be informed about during the irradiating ultrasonic and the current ultrasonic level with the volume of acoustic output.
