tinnitus can be hereditory, or from hearing damage
myself, i have a family history of deafness or at the least some hearing problems.
my mum has a buzz type of tinnitus. like the buzzing power lines make on a hot day.
mine is a high pitched tone, much like the ones you hear in a hearing test.
tinnitus is actually your ears thinking they hear a sound when they are not.
this is why some find actually making some type of noise (eg fan, radio etc) will make it go away... your giving your ears something to tune into,
instead of tuning into a defect in your hearing.
hearing damage is irrepairable, and your ears do not feel pain with loud music.
you could have it cranking and not realise your destroying your hearing.
theres a bunch of hairs in your ear drum that vibrate when you hear noise, and send the signal to our brain which we know as a sound.
think of them like blades of grass that make up your lawn
listening to loud music, noises etc for extended periods is like getting your lawn mower out and cutting the grass down to dirt level, leaving no
blades, only the roots.
once this has happened to your ears they can never grow back. and thats what makes you feel like someone turned down the volume, because those hairs
are not long enough to easily detect the vibrations.
effectively, you will now have to listen to everything at a loud volume just to get those hairs to give a response.
