July 28th 2023Watch the video to learn how a sound suppressor is built from start to finish. It’s a lot more complicated than you think — there are many stages to the process. SilencerCo explains in the video below how they make a SilencerCo Octane45 suppressor. SilencerCo asks: “What exactly goes into making a silent? It’s more than you think. Our streamlined process involves more than a few steps. From cutting metal, to chemical baths, and to quality control at every step, it is a complex process. Watch our latest video, HOW IT IS MADE: Octane, to get a peek behind SilencerCo’s doors.Photo courtesy UltimateReloader.com.How Loud Are Unsuppressed Rifles?
Firearms are Loud — 140 to 175 dB. ASHA explains that “almost all firearms produce noises above 140 dB.” Hearing damage can be caused by exposure to noises greater than 140 dB. A small.22 caliber rifle can generate noises of around 140 dB. Big-bore rifles, pistols and other weapons can produce sounds over 175 dB. Fire guns in an area where sound can reverberate or bounce off walls and structures to make the noise louder. This can increase the risk of hearing damage. Adding muzzle brakes and other modifications can also make the firearm louder. Hearing loss can occur with just one shot for people who don’t wear hearing protection.

It depends on the rifle and the cartridge. Also, it depends on how effective the suppressor is. American Hunter explains that suppressors slow down the speed at which propellant gases are released from the cartridge. These gases are responsible for the loud boom heard from miles away. The series of internal baffles in a suppressor slows down these gases, so that they don’t all come out at once. This muffles the sound. Many commercial suppressors are capable of achieving sound suppression levels between 30-35 dB. Zak Smith, Thunder Beast Arms, says that some manufacturers publish values which are not reproducible or use an ad hoc test in place of a mil-spec. In many cases, we’ve tested suppressors that were advertised as having 30-40 dB of reduction and found they actually have a high 20s. “Again, this is why we recommend that hunters wear ear protection such as electronic muffs even when shooting suppressed.
