I have an ultrasound cleaner and it definitely vibrates and is noisy.

[tadfisher]

Applause for the pun.

When working with ultrasound, I think of it the context of a micro-agitator versus the large scale shaking, snipping, and slapping clothes against rocks methods.

Every ultrasound device makes sound, sometimes a lot of sound, because it's vibrating all of the materials, liquids, and air around it.

[tadfisher]

So does every piece of baryonic matter in the universe, in which case I am proud to be an ultrasound device.

[antonvs]

Affirming the consequent fallacy.

"Ultrasound machines vibrate everything around them therefore make sound" does not imply "I vibrate everything around me therefore make ultrasound."

[cratermoon]

but that could be fixed by isolating the device from the environment, the ultrasound would not be heard, unless you're a bat.
