> You know the thing that you should never do because it makes you

you blind. In France it used to make you deaf. Of course nobody tells
that anymore to children and it was even never told to me; I learned it
from jokes. But it is always satisfactory to understand the cause of
things, therefore I suggest this explanation :-)
More seriously, when I was working at CERN, where many electronics
racks are used with very noisy fans, a study was published which showed
that you become deaf to certain frequencies emitted by the fans but you
recover audition capability if you stop being exposed to these
frequencies for some time. I think mostly very high power noise or
music, and of course ageing, can cause permanent audidion loss.
