There are earplug/hearing aid sized ones that do just this. I know of several hunting buddies that like to use these, since they can crank the sensitivity way up to hear the deer coming, but the circuit damps down when they shoot, so they don't deafen themselves. The next thing will be to get a Mickey Mouse hat that allows long distance directional stereoscopic reception.
