The sound? Well, ultimately sounds are just those hairs and your cochlea and eardrum and all that getting hit by vibrations in the air and sending signals to your brain which get interpreted; damage the equipment so it sends signals even when there's no vibrations in the air hitting it, and you have your non-physical sound. Same way phantom limb syndrome works.
However what if the damage doesn't cause signals in the absence of sound? What if tinnitus is actually the cochlea itself (or something/s in the apparatus anyway) physically vibrating and producing that whining sound? Like a mosquito's wings beating.
Makes sense, and I've also read it's very hard to study as well. Different causes with the same perceived sound sounds like a diagnostic nightmare
It seems like it could be some kind of feedback loop where the false signalling is actually inducing a physical response that can be recorded under ideal conditions. At the end of the day, the eardrum is an audio transducer, and every other such device we know of can make "fake noise" by being pushed into an unstable state.
