It's an annoying feature in some power electronics, they design the switching frequency to be outside of most peoples' hearing, but not high enough to be completely outside.

I pity the dogs and cats especially!

I suspect the switching frequency is completely outside of any humans hearing range. But there are probably components that have resonant frequencies that are both within human hearing range, and happen to be closely divisible to the switching frequency, and thus will couple to the switching signal and vibrate.
