Re: Breaking News : AAC Silencer Shoot Cancelled
<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: RollingThunder51</div><div class="ubbcode-body"> An event set on nuetral ground would welcome all and make the makers come forward and compete in all areas of performance (not just dBs...say, accuracy (two big solicitations just finalized on .338), drop test (many bit the dust of basic drop test...yes, all QD), weight, etc.,etc.

A question and a comment...
When you say all QD do you mean all QD failed, or all failures were QD? If some QD's passed, would you mind letting us know who?
Regarding testing, db's is not a sufficient measure. You need someone with real mics, and real software. The reduction in peak, as seen on spl meters is important for the guy with his ear next to the gun, but it isn't the only effect on sound. For people near, the average level is important in terms of comfort. For obfuscating your location, compressing the envelope (changing the impression like was it a crack, a thud, a rumble) is gonna make a bigger difference than either because the event is completely distorted before it even reflects off of terrain surfaces.
Peak db
rms db over say the time period before 70db is reached (depends on environment if that us practical, but you can pick a good decay level after gathering the audio)
time to reach 70db
resonant frequency
Before and afters of the above, both full spectrum and at a few choice frequencies, measured from behind, beside, and in front of the unit, please.
