Audio has its own equivalent. It's not noise, it's more of a gargly quality. You can hear it very clearly at more extreme compression settings.
The overtone movements become disassociated and start splitting up into disconnected sine wave blocks. Transients also become softened.
With MP3s this is obvious at the high end, while lows/mids sound passable. The compression algorithm has more frequency bins at the high end, so the damage is more obvious there.
There's also a loss of low-level detail. Reverb tails lose definition, and the music loses front-to-back depth.
