Watch this video to see how a sound suppressor (aka “silencer”, “moderator”, or “can”) is constructed, start to finish. It’s more complicated than you might expect — there are quite a few stages in the process. The video below shows the fabrication of a SilencerCo Octane 45 suppressor:
SilencerCo writes: “What, exactly, goes into making a silencer? It may be more than you’d expect. From cutting metal to chemical baths, to extensive quality control every step of the way, our streamlined process is more than just a few steps. Watch our newest video, HOW IT’S MADE: Octane 45, to catch a glimpse behind SilencerCo’s doors.”

How Loud Are Unsuppressed Rifles?
Firearms Are Loud — 140 dB to 175 dB. ASHA explains: “Almost all firearms create noise that is over the 140-dB level. Exposure to noise greater than 140 dB can permanently damage hearing. A small .22-caliber rifle can produce noise around 140 dB, while big-bore rifles and pistols can produce sound over 175 dB. Firing guns in a place where sounds can reverberate, or bounce off walls and other structures, can make noises louder and increase the risk of hearing loss. Also, adding muzzle brakes or other modifications can make the firearm louder. People who do not wear hearing protection while shooting can suffer a severe hearing loss with as little as one shot[.]” Source: ASHA, Recreational Firearm Noise Exposure.
How Much Does a Good Suppressor Really Reduce Firearm Sound Levels?
That depends on the rifle, the cartridge, and the effectiveness of the suppressor. American Hunter explains: “Suppressors retard the speed of propellant gases from the cartridge that rapidly expand and rush out of the barrel. It’s these gases that produce the loud boom that’s heard for miles. A suppressor’s series of internal baffles slows these gases so they are not all released at once, thereby muffling the sound.” Many good commercial suppressors can achieve 30-35 dB sound suppression. However, Zak Smith of Thunder Beast Arms says: “There are a bunch of manufacturers who publish values that are not reproducible, or use an ad-hoc test instead of a mil-spec test. In many cases we’ve tested the exact same suppressors they’ve advertised with 30-40 dB reductions and found they are actually in the high 20s instead.”
Again, for this reason, we recommend that hunters use ear protection, such as electronic muffs, even when shooting suppressed.
