The solution should be to turn the speakers the other side so that
musicians get more concerned ;) A few weeks ago, I intended a concert
which was really loud and very noisy too, fortunately I was enough close
from the stage to get my ears behind loudspeakers, and I really realised
that musicians do not hear the sound volume they produce in the hall,
even whith feedback speakers ...
But I noticed too that most of the time, musicians are not really
responsible for this problem, but rather the venue's owners who prefer
to get more quantity (in term of kW) than quality when they invest in
sonorization system ...
For the everybody sake, I learned recently that hearing loss is not
irreversible unless you get to hospital soon enough. If you intend a
concert and after a good night sleep your ears still buzz, it is not too
late (until 48 hours) to go to hospital and get cured but it is
obviously not a solution, I think everybody had understood;) Good to know.
To get information about it (in french sorry), this site make good
