Has anyone else found an ultrasonic scaler very loud while in use, and to cause tinnitus for a couple days after?

Please don't give yourself tinnitus. Always wear protection (for your ears).

For the patient with an ultrasonic scaler in their mouth, are you saying that that a significant percentage of harmful noise is coming in through the ear canal, so conventional ear protection would help?
