The difference was this silly Goon fired a gun right next to his left ear.

Mr. GREER - The second one didn't sound any different much than the first one but I kind of got, by turning around, I don't know whether I got a little concussion of it, maybe when it hit something or not, I may have gotten a little concussion that made me think there was something different to it. But so far as the noise is concerned, I haven't got any memory of any difference in them at all.
