Ultrasound
Ultrasound is high-frequency sound that is inaudible, or cannot be heard, by the human ear. However, it may still affect hearing and produce other health effects.
Some equipment and tools in the workplace produce ultrasound, such as ultrasonic welders or ultrasonic cleaners.
If your workplace deals with ultrasound issues, your employer can provide you with more information.
