But there may not be more brain cells dedicated to hearing. The visual processing and interpretation cortex is situated in a completely different area of the brain to the audio processing area, and I don't know of any evidence that shows that neurons in the visual cortex are respecialised for audio or any other sensory processing after you lose your sight. And if sight is lost due to a problem in the brain, rather than the eye, like in the primary or association visual area, then obviously the neurons will not be used because they're damaged. Also, the brain uses parallel processing which does not improve with less tasks.
