A Virginia Congressman has introduced legislation which will take suppressors (aka “silencers”) off the NFA list and make them much easier to purchase. That’s a good idea because a quality suppressor can reduce firearm sound levels by 30 decibels (dB) or more. U.S. Rep. Ben Cline’s Hearing Protection Act (H.R. 404) would remove firearm suppressors from the list of restricted items under the 1934 National Firearms Act (NFA). That would reduce costly licensing ($200 per suppressor) and burdensome background checks. Instead, suppressors would be regulated under the 1968 Gun Control Act (GCA) with the same type of background check done with retail firearm purchases. The legislation would also amend statutory suppressor definitions.
Under current law, an individual purchasing a suppressor must locate a regulated NFA Class III retailer, complete a Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) Form 4 with the model and serial number of the suppressor, and obtain two passport photos and fingerprint cards from a local police department. The local chief law enforcement official must receive a completed copy of the application. Then the form, photographs, and fingerprints must be sent to ATF along with a check to pay the $200 tax. The customer can obtain the suppressor from the NFA Class III retailer upon an additional background check through FBI’s National Instant Criminal Background Check System (NICS).
Congressman Cline’s legislation would eliminate those requirements and make suppressors available with the same type of paperwork and background check required for a firearm. H.R. 404 would also clarify the definition of suppressors, ensuring that components like mounts, baffles and end caps are not erroneously classified as standalone suppressors or “silencers”.
“Congressman Cline’s Hearing Protection Act will have the federal government recognize firearm suppressors for what they are. These are accessories to a firearm that make recreational shooting and hunting a safer experience”, said Lawrence G. Keane, NSSF Senior V.P. and General Counsel. “These safety devices reduce the report of a firearm to a level that won’t cause instant and permanent hearing damage.” There are currently 2.6 million legally owned suppressors in the United States.
Suppressors, On Average, Reduce Noise Levels about 30 Decibels
In an article for Ammoland, gunwriter Sam Hoober says that you can expect about 30 decibels (dB) of noise reduction from the average suppressor: “Looking at a few different products, SilencerCo attests their suppressors reduce the sound pressure of a 9mm gunshot to anywhere from 125.7 dB to 131.5 dB, depending on the model. Advanced Armament Co, another popular supplier, attests a 23 dB to 33 dB reduction or down to 127 dB. Liberty Suppressors, another manufacturer, attests a reduction of 24 dB to 38 dB, depending on model and other factors. In short, we can presume something on the order of 30 dB of attenuation as an average.”
Using that 30 dB number you can quickly discern that you’ll still need hearing protection — good hearing protection — when shooting any suppressed firearm (even a .22 LR). “Spikes of 130 dB and more can result in permanent hearing damage instantly”. Source: NRA Blog.
Firearm suppressors (aka “silencers”) reduce the report of a firearm from a level roughly equal to that of a jet taking off which causes instant and permanent hearing loss to one that is safe, but still equal to a jackhammer. That decibel level will not permanently damage hearing. Suppressors work similar to a car’s muffler, redirecting exhaust gases.
