What i do not understand is why normal hearing tests were seen as a counter argument to the brain compensation for hering loss theory. If the brain compensated for the loss of nerve or hearing cells, the signal should be back to normal but with more noise, the failure of adaptation of the brain to the noise results in tinnitus. To have patients with normal or nearly normal hearing tests but tinnitus would be expected.
