Why can't ear nerve be healed?!
Question: Why can't ear nerve be healed?
Is it lack of biological knowledge? Or is it lack of equipment for the surgeries?
Answers:
Both.
Medical science hasn't been too good at repairing nerves
though techniques are getting better.
The aural nerves pass through the skull and are very difficult
to get at.

It is the nature of nerves. We have yet to figure out a way to repair any given nerve, so ear damage due to noise cannot be fixed, only eased.
