If a whumpee was bound, bildfolded and made to hear loud music/noises trough headphones in order to not eavesdrop on whumper in a long period of time, what kind of repercutions would that have to whumpee besides headaches?

That kind of exposure to loud noises can cause tinnitus, nausea and vertigo, ruptured eardrums with possible mucus-like or bloody drainage, and if it’s bad enough, permanent hearing loss.
