At least within the house - we moved around a lot, but I lived in a few three storey stonework houses, and could generally tell from 'the other end' of the house if the TV was on.

I don't recall hearing the same noise from fridges though!

It only works with CRT TVs though. It's a 15khz tone, due to magnetostriction in the flyback transformer: https://en.wikipedia.org/wiki/Flyback_transformer
