MIL-STD-1474D, MILITARY STANDARD: DESIGN CRITERIA STANDARD, NOISE LIMITS (12 FEB 1997).
This standard establishes acoustical noise limits and prescribes testing requirements and measurement techniques for determining conformance to the noise limits specified herein.

But there is not that simple to just follow this design criteria. The weather, temperature, barometrical pressure and surface changes troughout the year and will give different data. Therefore we do calibrate our equipment and tests against prior gained data to make shure we get consistent data we can trust.

We need to make shure that we measures with exactly same gun and ammunition in the same location under as equal atmospherical conditions as possible. And on top of that - we do also test our competitors products under these criterias.

Else we would´nt know that we make better products!

With each silencer you see a graph containing the raw data we have. As we gain more data per caliber we will give you access to this data too.

We do not supress data - we supress sound.
