Listening to music in high volume is harmful because it can hurt the eardrum.People with good hearing have tiny hair cells that line the inner ear
and these transmit signals to the brain, which are interpreted as
sound.Listening to loud music can flatten these hairs, and
although they normally spring back into place, noise damage over a long
period can cause them to snap.The problem – and one that many people don't realize – is that these hairs do not regrow and so any damage is permanent.
Hope this helps u.......^_^
