I probably misstated my original question somewhat. I know that a suppressor is the only thing that will reDuce the sound signature but what about redirecting it? I've seen the linear compensators that direct the blast forward. Would those have a noticeable effect?

tallwalker, that's a good idea. Everybody wears muffs but I'm sure that few are also wearing plugs. I always have some in my range bag so I'll offer them to nearby shooters.
