I'm about 80% deaf in one ear, so instead of higher frequencies I get permanent tinnitus, which is basically exactly that - it varies according to things like heart rate. It's like listening to an old modem, or something like a ZX Spectrum loading a game. 24x7. It came on as an adult, so it took a bit of getting used to - some people can't cope and suffer depression or even become suicidal over it.
