Abstract
An ultrasonic treatment apparatus includes a sound source, a frequency setter and a drive signal generator. The sound source emits ultrasonic waves. The ultrasonic waves are finite amplitude acoustic waves including a first signal frequency and a second signal frequency. The frequency setter sets the first signal frequency and the second signal frequency in accordance with a target position of a treatment object with respect to the sound source. The drive signal generator is configured to generate a drive signal and to drive the sound source. The drive signal is a signal which causes the sound source to emit the ultrasonic waves.
