What is a word that describes the sound of an electronic device?

whir
whirrrr

buzz

do you mean that high pitched noise that like, a tv screen makes even when its blank? I dunno anyway, just wondering.

frequency?

Audio pros use a lot of adjectives to describe perception of hearing…but perhaps your term is more general?

“Bandwidth”? The bandwidth is a term that describes the low-to-high range of a sound, especially in situations where the natural, full-frequency sound would be narrowed if the sound is obstructed by walls, such as in a ‘narrowed bandwidth’ sound…

“Rolled-off” describes the tendency for high frequencies to become decreased or attenuated by walls…

“Band Pass” describes a situation where a sound has some of its frequencies cut off while others ‘pass’ along…

“Bass Bin” is a speaker that only plays low (bass) tones)...

Going in the right direction? Where might you have heard this used in context of a conversation or other usage?

Is it “Cut Off”?

white noise?

Warble?

I believe is buzz as when you hear a buzzing sound, usually comes when the current path is obstructed. This is the same sound you hear on overhead wires near transformers where there is a small gap between conductors. Changes in the magnetic field produced by electrical appliances can cause dramatic transformations in radio noise, and electromagnetic (radio) noise as well.
