For all those headphone-addicts, it maybe is a good idea to add something like a limiter, or just some hard clipping (resulting in some distortions, if the sounds are too loud) to the sound-output, in order to protect the ears..
From time to time you have simultaneously exploding granades, or eg. that bug when a sniper tries to punch, but one hears him shooting several shots at once..
Generally talking about all the situations, when a soundfile is played multiple times rapidly.
Any headphone-users around??
