You know what they say, when you presume you make a pres out of u and me

Then the dog barking and the cat screeching through the house will do it then.

Ultrasonic welders sound like all daemons of hell rising up to get you. So... I wouldn't be too sure.

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

I think that's just a sound cleaner.

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.

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

Affirming the consequent fallacy.

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

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