How loud are brakes, to the shooter, in a hunting situation, in the woods?

[QUOTE="aspenbugle, post: 1342010, member: 6481"] JE, no worries. I agree, debate is good - so I appreciate the kind, well-thought-out response. I 100% believe you reported exactly what you observed. The sources I cited actually agree with your observations for most situations. I read one more that I didn't post that also agrees that they are basically the same loudness to the side (which seems a bit surprising to what I would have thought). I guess, enough of the normal noise cone reaches your ear to the side, to be about equal with that of a brake. So you and the science I read agree there. The place they differed was going 180 degrees opposite the muzzle blast, back where the shooter is. That is when other studies showed a separation between braked barrels vs. unbraked barrels. Unbraked barrels sent as much noise to the side, but at some point that tapered off as you moved the sensor toward the shooter, but muzzle brake noise didn't. At the shooter, muzzle brakes were 6-15 db louder, and that is with at least 3 good research sources that agree. I don't doubt your meter said there wasn't a difference, but (please don't take offense), just because an instrument is consistent, doesn't mean it's consistently good. (McDonald's burgers are consistent, but...:) ) Just conjecture, but the reason your data may not agree with what else is out there is your Db meter, although consistent, was not be of the quality needed to accurately measure super-short, high-intensity gunshot noise.
