Re: .22 question

Any chance of showing what an unsuppressed .22 colibri or super colibri will meter? It would be a good comparison as the colibri is readily available to most folks. I have some Colibri. Next time I'm out with Robert I'll test it. I have no guesses as to what it will meter, but I know it is quiet an...

I think the answer is yes AND no.

More volume is better. We have played with some .223 cans that were short and fat but the didn't seem to work as well as a longer thin(er) one.

There must be some ideal ratio for volume to length that deals with the impulse of the expanding gasses, etc.

Thoughts?

I would also assume, since we are all advertising dry/wet db reductions, that the cans will be tested dry and then wet, correct? Thanks, Doug Yes they will be tested both ways. When the 9mm pistol tests were done (soon to be published), after first ensuring that the suppressors were dry, we fired t...

I think it is something like 6 dB per meter - it is burried somewhere in one of rsilvers posts about calculating the SPL from an M4 at 2 meters instead of 1 meter.

Re: Why doesn't anyone make

Disclaimer: Kevin/Mike, if you make these, I want one for the intelectual property rights :P an integral AR15/22 can? The barrels from Kuehl would be a good base, you could have a traditional SD look or who knows what else (maybe all the can under the handguard, regular barrel out the front for the...

Diagnostic Suppressor testing & Repair

Suppressor REPAIR: Using state of the art testing equipment, we first diagnostically test the suppressor*. This produces a sound histogram from which we calculate the net SPL dB reduction of the suppressor. Taking this result we compare it to the published values and restore the suppressor to optima...

Flight Noise

Robert and I have already discussed measuring flight noise, and impact noise.

The main issue is so much to do, so little time.

Keep Quiet,
