Birds don't go deaf because they can regenerate the hair cells (sensors) in
their inner ear. Mammals can't.
Hair cells die when exposed to prolonged stimulation due to loud noise, which
is why humans get industrial deafness. Regeneration of hair cells in birds was
discovered about 30 years ago and has been the subject of much research because
of its implications for potentially restoring hearing in humans.

Anyone who's had an Eclectus Parrot on their shoulder will share my feelings
about how unfair this is.
