Sound Testing Video - Bore and Porting.mov

I know it's been a while since you guys released this data... But is it possible that the primary acoustics from the gun were simply overwhelming the secondary acoustics of the barrel? Proteges aren't quiet guns by any means... If you guys were setting out to prove that a ported barrel won't quiet a loud gun, then you certainly did prove just that.

So looking at these spreadsheets... Basically, nothing really makes much of an impact?

your sound tests would be better if the acoustics of the room you were doing them in werent a basement. being a musician i know that when doing any sort of test a basement isn't a good choice.

@stompnd And as a professional sound guy - I agree, in part. In this case we're doing relative measurements - meaning we're looking at changes. Since every item we test is affected by the acoustics of the environment in the same way - it's still a valid way to compare two signals. Optimal would be an anechoic chamber - but that's certainly not going to happen on our budget. :)

@brycelarson thats true, i guess it'll react the same way cause the acoustics are the same for each test victim, it'd just be more fun to do it in a anechoic champer =)

you guys do good work
