Yes, that has to be. The brain can adjust to lack of input, or recurring input. The brain can super adjust on the fly, quickly. It is not our brains doing this, it is the system between the cochlea and the brain.
By killing the hair cells really quickly, the middle man between the auditory cortex, the auditory nerve, the dorsal cochlear nucleas flips out and makes new connections haphazardly becomes hyperactive and the brain doesn't ever get a chance to filter this out because it is in fact coming from the peripheral nerves. It is a genuine stimulus coming into the brain. Also, the hyperactivity affects the visual system too. It has too. That would explain the disruption that causes floaters and visual snow. The answer is to restore the input, or retrain the auditory cortex like Shore and Lenire. The best thing is to restore hair cells I think. The rest of the auditory system just cannot adjust properly with the rapid adjustment from damaging the cochlea and cannot nor will not adjust properly except in a very small amount of cases.
I stand behind this 100%
