Some observations based on the "noise" section of the "Introduction to
Pollution" course I used to teach:

As Sandy has noted, hearing damage from noise exposure is well-known and
well documented; documentation includes observation of the causal
relationship in many individuals.  The damage is frequency-dependent, and
occurs mainly is the range where hearing is most acute, which is also the
frequency range of ordinary human speech (about 1000 to 2000 Herz).   Lower
frequency hearing suffers much less damage.  It is also true that women have
a bit better high-frequency hearing than men, and would notice hearing loss
in this range more than a man would.
