This video explains the methodology and process used to test and determine the exact loudness of a gunshot. It focuses on the 'how-to' aspect of measuring firearm sound levels, presumably involving specialized equipment and procedures.
This video conducts a performance test of multiple 30 caliber suppressors, adhering to Mil-Std 1474D protocols. Utilizing a Bruel & Kjaer impulse sound meter and PPU .308 Winchester ammunition, the analysis compares suppressors from brands like AAC, SilencerCo, SureFire, Griffin Armament, and Dead Air. The testing is performed on both a 5.56mm rifle and presumably a .30 caliber platform (implied by ammo and suppressor calibers). Data includes logarithmic and linear averages, with explanations of decibel perception and hearing safety standards. Links to detailed results and further acoustic information are provided.
