Silencer or Suppressor?
The terms “silencer” and “suppressor” are used interchangeably in the firearms community, and we are here (hear?) to tell you the story of how this came about and which term is more correct.
Going back to the 19th century, “devices for the lessening the noise of firearms” were patented as far back as 1894. However, it wasn’t until Hiram Percy Maxim, a man uniquely obsessed with making loud things quiet for the sake of hearing protection, that the first trademarked “Silencer” (big S) came about in 1909.
Dr. Shush
Why was Maxim interested in hearing protection? A big part of this was because his father, Sir Hiram Stevens Maxim, generally regarded as the inventor of the modern belt-fed machine gun, went quite deaf after long periods of exhibiting his guns for interested clients sans ear protection.
The junior Maxim began working on his acoustical mufflers in 1902 and by 1909 started securing a series of patents on “Silencer” and “Silent firearm” devices. His Connecticut-based company first was branded as the Maxim Silent Firearms Company, and later the Maxim Silencer Co.
Maxim, a graduate of the Massachusetts Institute of Technology, even marketed himself as “Dr. Shush.” Following in his father’s footsteps, he was his own best spokesman for his products and stressed how they made shooting safer and more enjoyable.
He successfully landed a series of large newspaper interviews in 1909.
The company sold not only a series of Silencers but also couplings to attach them to barrels and instructions for gunsmiths and hardware shops to thread barrels for the screw-on devices, interestingly advocating a rather fat (by today’s standards) 20-thread pattern. Silencers could be purchased by mail order for $5, about $160 in today’s inflated dollars.
Were Maxim’s designs truly silent? Not at all, but it was great branding, especially when he had to fight for market share against a crowded field of contemporary competitors. Matthew Moss, writing for Small Arms Review, notes at least nine inventors at the time (Harry Craven, Anthony Fiala, Charles H. Kenney, Herbert Moore, Robert A. Moore, Eugene Thurle, R.M. Towson, Andy Shipley, James Stinson, et. al) were seeking patents for similar devices, with several ultimately going on to market them with mixed success.
There are few period tests between these 1910s-era firearm mufflers. The Army’s Ordnance Bureau, which ordered 100 of Maxim’s devices and 100 from Robert A. Moore’s firm for tests on the M1903 Springfield, preferred the former, noting that “it was possible to give perfectly audible instructions when the Silencer was used.” It was estimated to have reduced noise by as much as two-thirds. Given the technology of the era, that had to be what could best be described as a wild guess.
Common Vernacular
In the end, Maxim’s Silencer (which wasn’t silent), won the marketing war and emerged as the Dr. Pepper among a crowd of Mr. Pibbs. Teddy Roosevelt used one to quietly zap tin cans around the yard without disturbing the neighbors and exchanged personal correspondence with the inventor. Period cartoons even gagged about noisy diners being offered “Maxim Soup Silencers.”
Maxim’s company went on to market Silencers for motorboats and automobiles on much the same principle.
The public had so associated the Silencer with firearm report moderators by 1934 that the National Firearms Act hearings – which largely started as an effort to ban most guns in the country, including all common pistols and revolvers – used the term no less than eight times. While handguns escaped the government regulation, silencers (little “s”) did not. Never being banned outright on the federal level, they were instead hit with a $200 tax, which adjusts out to $4,800 in today’s terms. The silencer term, enshrined in 1934, is still on the books in the U.S. Code, retained in the 1968 Gun Control Act, and used by the ATF today – an organization that was only established in 1972.
It even entered Merriam-Webster.
In the meantime, the repressive tax largely killed the American suppressor industry until the 1970s, when companies like Mitch Wer-Bell’s SIONICS and Dr. Phil Dater’s AWC (now Gemtech) began quietly (see what we did there?) operating. By then the stifling NFA tax, frozen at $200 since the Depression, had been whittled down to a more manageable outlay thanks to the federal government’s habit of printing fiat currency in an economic pinch after Nixon ended the gold standard.
What About the Term Suppressor?
In today’s terms, “suppressor” has largely supplanted and replaced “silencer” in use, starting with patents filed in the 1980s. The term is more correct as, while the devices moderate and reduce the sound signature of a muzzle report, they do not remove it. In most cases, despite what Hollywood would lead us to believe, while suppressors paired with subsonic ammunition that removes the “crack” of a projectile breaking the sound barrier can be made hearing safe, you can still hear the gunshot, albeit muted.
As detailed by the American Suppressor Association, suppressors typically “reduce the noise of a gunshot by an average of 20 to 35 decibels, which is roughly the same as earplugs or earmuffs.”
Even the most effective suppressors, on the smallest and quietest calibers (.22 LR), reduce the peak sound level of a gunshot to between 110-120 dB. To put that in perspective, according to the National Institute for Occupational Safety and Health (NIOSH), that is as loud as a jackhammer (110 dB) or an ambulance siren (120 dB). For normal caliber handguns and rifles, suppressed sound levels routinely exceed 130 dB, just shy of OSHA’s “hearing safe” threshold of 140 dB.
For reference, check out this Taurus TX22 with a SilencerCo Switchback, one of the better rimfire cans on the market, firing standard velocity .22 LR ammunition.
It’s quieter, but you can still hear it.
In addition to noise abatement and hearing protection, the use of a suppressor can also help with firearms training, especially as it curbs the traditional “crack” to a more manageable “pop.”
Is it a “silencer?” Not really.
Is it a “Silencer?” Only if made by Mr. Hiram Percey Maxim’s Silencer Company.
Is it a suppressor? Yup.
So in other words, to turn a phrase, a Silencer is a suppressor but a suppressor is not a silencer, despite what the media says about potatoes.
