Are sound suppressors useful in competition shooting? In some disciplines, and in venues where sound “moderators” are permitted, the answer is “yes”. In a past edition of Shooting Sports USA eZine, you’ll find an interesting article about the use of sound suppressors (aka “cans”). The article explores the use of suppressors in Europe and in tactical matches in North America. You’ll also find an explanation of the rules and regulations governing suppressor ownership and use in the United States.
Shooting Sports Editor Chip Lohman tests three rifles from the bench and found that sound suppressors did not harm accuracy. In fact, all three test rifles (one each in .223 Rem, .308 Win, and .338 Lapua Magnum), shot slightly better 5-shot groups at 200 yards when a suppressor was fitted to the barrel. However, the suppressors did alter point of impact. Interestingly, velocity standard deviation (SD) values were lower with suppressors in place for all three test rifles. This observation calls for further study.*
So the use of suppressors in competition could be a good thing. However, in the United States, current NRA rules prohibit the use of sound suppressors. NRA Rule 3.16.1 subsection (a) states: “Sound Suppressors are not authorized for use in High Power competition.” In addition, there are some practical problems with suppressors — the heat rising off of a naked suppressor can create mirage problems (that’s why some shooters wrap their cans with a cover).
Despite such issues, now commonly see suppressors on rifles used in tactical matches and PRS/NRL events. For example, many competitors in the Steel Safari field challenge match use suppressors. The photo below shows our friend Zak Smith competing in the Steel Safari with his suppressed Accuracy International rifle.
Commentary — What Can We Conclude?
Obviously, this three-rifle SSUSA test was not definitive. One well might observe different results with different types of suppressors, fitted to different kinds of rifles. Mounting a suppressor to any barrel will certainly affect harmonics and “tune”. But this SSUSA study does suggest that tactical shooters, who are allowed to use suppressors in competition, may find that the benefits of suppressors (significantly reduced recoil and less noise) outweigh any meaningful accuracy loss, at least in PRS-type matches.
NOTE: The article cautions that one should not extrapolate too much from the SD numbers, given the low number of test shots. Chronograph-maker Ken Oehler, when asked to comment on the SD values stated: “[You should] report the observed SDs, but draw no conclusions until… you can do more testing with larger sample sizes.”
Qualifications to Obtain a Suppressor
To legally obtain a suppressor, you must fill out Federal Forms and pay a $200 fee to the ATF. You must also pass BATFE background checks and otherwise comply with Federal and state laws. States can regulate suppressor ownership or use, so be sure to check the laws in your area. On the federal level, the process to acquire a suppressor is regulated under the National Firearms Act of 1934.
“Science tells us that exposure to continuous noise of 85 dB for eight hours is enough to cause permanent hearing loss, and worse, spikes of 130 dB and more can result in permanent hearing damage instantly.” Source: NRA Blog.
The Risk of Hearing Loss
Hearing loss can be progressive and irreversible. If you are a shooter, this is serious business. As the NRA Blog cautions: “You may not even realize you’re harming your hearing. Hearing loss occurs gradually, and can go effectively unnoticed until symptoms become severe. By then, the damage is done.”Effective hearing protection is a must whenever you are shooting firearms or when you are in the vicinity of gun-shots. For ultimate protection, we recommend a good set of tapered foam earplugs, topped by ear-muffs. However, there are situations when you may prefer lighter-weight hearing protection that can be quickly removed. For example, if you are standing well behind the firing line as an observer, or if you are working as a rangemaster or waddie some distance away from the shooters.”
Sound Levels for Common Noises:
9mm Luger pistol: 160 dB
Jet aircraft engine (near): 140 dB
.22 LR pistol: 134 dB
Normal human pain threshold: 120 dB
Noisy Nightclub: 110 db
Riding Motorcycle at 65 mph: 103 db
Power Lawnmower: 95 dB
Hearing damage possible: 85 dB (sustained for 8+ hours)
Ringing Telephone: 80 dB
Normal conversation: 60 dB
What about suppressors? If you use a suppressor is it OK to dispense with hearing protection? Not really. Even the most effective suppressors, on the smallest and quietest calibers (.22 LR), reduce the peak sound level of a gunshot to between 110 to 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. Accordingly, we recommend use of hearing protection even when shooting suppressed.
Compact, Low-Profile NRR 27 dB-Rated Ear Muffs
Many hunters and competitive shooters prefer low-profile ear muffs. As these typically have a lower Noise Reduction Rating, perhaps NRR 22-27, we recommend running earplugs under muffs. If you use low-profile electronic muffs, such as Howard Leight Impact Sport Muffs, you should still be able to hear range commands even with plugs underneath.
Another good option for hunters and range visitors are hearing bands, basically earplugs connected with a semi-rigid plastic band. These banded products provide “quick access” hearing protection for hunters. You can keep them handy around the neck while spotting game, and then insert the plugs before shooting.
Howard Leight MAX NRR 33 Earplugs, Just $8.44 for 20 Pairs
These Howard Leight NRR 33 Max-1 Plugs are your Editor’s favorite foam earplugs. Between shooting, motorcycling and mowing lawns, I probably have Howard Leight foam plugs in my ears 3-4 days a week. They are comfortable and the flared outer edge helps the NRR. You can get 20 pairs for $8.44 on Amazon. There is also a Max-30 corded version, with the same excellent 33 dB Noise Reduction Rating. Get five pairs of Max-30 Corded Plugs for $5.99 on Amazon, or 100 pairs of Max-30s for $27.99.
Note, if you prefer thin, light-weight earmuffs, we recommend running earplugs underneath for double protection while shooting firearms (or when you’re on the firing line). Sound experts tell us that running plugs and muffs together can effectively improve your effective noise reduction by 4-7 dB NRR.
Share the post "How High dB Sound Hurts Your Hearing, Plus Protection Options"
Firearms enthusiasts definitely need to employ hearing protection at all times when shooting or visiting an active range. Just a few moments of unprotected sound exposure can have permanent negative effects. For best protection, consider “doubling up” — wearing good foam plugs under quality muffs. This allows max sound reduction — as much as 5-6 dB quieter than good muffs alone. If the muffs are electronic (with filtered microphones that block extreme sounds), you can still hear range commands.
So How Loud Are Gun Shots?
A pistol gunshot can reach 160 decibels (dB), and rifle gunshots can be even louder, exceeding 170 dB. This means you can do permanent damage to your hearing with just a few shots fired. 160 dB is 20 decibels over OSHA’s threshhold for safe noise levels. This is why it’s essential to always use hearing protection when you are anywhere near firearms being discharged.

This American Suppressor Association (ASA) Video explains that gunshots can measure 160-170 decibels, high enough to cause permanent effects. (See: 00:20 time-mark)

Hearing Protection Product Reviews
Shooters should have comfortable, effective muffs, preferably that allow normal conversations to be heard through internal electronics. For best protection, run good earplugs under electronic muffs. There are also electronic earbuds that provide protection, but these do not provide all the benefits of good muffs as some noise energy can be transferred through bone conduction.
The following videos evaluate a wide variety of earmuffs currently on the market. Some of the big muffs boast a 30 dB Noise Reduction Rating (NRR), while thin, muffs may only have a 22-23 dB NRR. Remember that decibel scale is logarithmic, so, according to the experts, a 3 dB gain represents twice the sound energy. So “this means that a small change in the number of decibels can result in a significant change in the intensity of noise and hence its potential to damage a person’s hearing. [F]or every 3 dB the sound level increases the impact on hearing health which is doubled. For example, 63 dB is twice as noisy as 60 dB. For every 3dB the noise level increases, the exposure time must be halved to keep the worker safe from harm.” Source: Institution of Occupational Safety and Health (IOSH).
Yes Hunters Need to Employ Sound Protection
According to Dr. William W. Clark, the current Director of the Washington Univ. School of Medicine’s Audiology/Communication Sciences Program, a “serious threat to hearing comes from recreational hunting or target shooting”. This is in large part due to the fact that many people choose not to use traditional hearing protection devices like earplugs and earmuffs because they want to be able to hear their surroundings. Multiple studies have found that between 70 to 80% of hunters never wear earplugs or earmuffs, and nearly half of all target shooters don’t consistently wear traditional hearing protection. Thus, it should come as no surprise that for every five years of hunting, hunters become seven percent more likely to experience high frequency hearing loss.
We recommend that hunters carry quick-insert plugs on a cord around your neck. These can be quickly deployed when you are getting ready to shoot. Or, get a lightweight neck band with earbuds, such as Howard Leight Quiet Band QB2HYG, Sellstrom Band, or 3M Safety Band, all with good Noise Reduction Ratings of 25 dB or higher. You can keep these lightweight bands around your neck for quick deployment.

U.S. Senator Mike Crapo (R-Idaho) has re-introduced the Hearing Protection Act which will make it easier to obtain suppressors in the USA. The legislation, S. 401, is co-sponsored by 24 additional senators. This U.S. Senate bill would provide greater access to firearm suppressors/silencers by removing them from the 1934 National Firearms Act. With this change in the law, suppressors could be acquired relatively easily, as is the case in the vast majority of other first-world nations. There would be no massive fees, burdensome applications, and long wait times to obtain an official $200 Tax Stamp. With a quick NICS check, a suppressor buyer could be approved, and not have to wait for months.
Wait times for processing Form 4 ATF applications for suppressors now average 11 months (315 days).
“This no-nonsense legislation by Senator Crapo would remove unnecessary and onerous regulations for an accessory that is nothing more than a muffler for a gun”, said Lawrence G. Keane, NSSF Sr. VP and General Counsel. “Suppressors are safety tools that reduce the sound of gunfire to a level that won’t cause instant and permanent hearing loss, enables more accurate marksmanship, and allows shooting ranges to be better neighbors. The Hearing Protection Act would reduce unnecessary barriers for this accessory that is currently regulated the same way as automatic firearms. Suppressors were originally listed under the National Firearms Act over poaching concerns during the Great Depression, but those fears proved to be unfounded. Suppressors don’t completely silence a firearm, only reduce the report from a level equal to a jet taking off to one similar to that of a jackhammer.”
The Hearing Protection Act would reclassify suppressors by removing them from the 1934 National Firearms Act. That would replace the current burdensome federal transfer process with a rapid National Instant Criminal Background Check System (NICS) verification, making the purchase process for suppressors similar to acquiring a standard rifle or shotgun (not short-barreled). The legislation would also tax suppressors under the Pittman-Robertson Act instead of the National Firearms Act, putting more funding into state wildlife conservation agencies.
Proposed Federal Statute Would Not Change State Laws
The proposed Hearing Protection Act would not change any laws in states that already prevent suppressor use or ownership, nor does it eliminate background check requirements. Suppressors are legal to own in 42 states and 41 states allow them for hunting. Similar legislation, H.R. 152, was introduced in the U.S. House of Representatives earlier this year by Rep. Jeff Duncan (R-S.C.).

In addition to traditional ear plugs and ear-muffs, band-style protectors provide a third sound-blocking option. Howard Leight, a top name in the sound-protection business, offers the popular “Quiet Band”, a device with soft foam plugs attached to a plastic band worn around the neck. This “Quiet Band” product is comfortable, easy-to-deploy, and surprisingly effective.
NOTE: We do NOT recommend these for normal, sustained use when shooting firearms, as when shooting a match. Use muffs over plugs for that. However, Quiet Bands work very well if you are spotting for a fellow shooter, or are near the firing line. These also work great when running noisy machinery such as leaf-blowers.
Three Quiet Band Models
There are three (3) types of Leight Quiet Band® sound protectors. We prefer the QB2 Supra-aural model (item QB2HYG, NRR 25).
The recommended QB2 Quiet Band positions cone-shaped foam pads next to the ear openings and holds them there with light pressure from the orange-colored band. There is also an Inner-aural version (item QB1HYG, yellow band, NRR 27), and a Semi-aural model (item QB3HYG, red band, NRR 21).
Our preferred QB2 Supra-aural (orange band) model is just as comfortable as the QB3 (red band) version, and offers much better protection. The QB1 Inner-aural (yellow band) model requires that you place the ear buds in the ear canal, so it’s not really any easier to use than conventional earplugs. That’s why we like the QB2 Supra-aural model best of all. Other users agree. Here’s what two QB2 owners had to say:
“I first saw these used by Hickok45 on YouTube and he talked positively about them. I got two and gave them a try. At first, I didn’t think they were going to work very well. After some fiddling, I found they work pretty darn good. With my ears, they fit the best if the band starts on top of my head, I insert the plugs then rotate the band behind my head. PRESTO, perfect fit. Shooting the 9mm and 12 gauge out back was comfortable with no ringing afterward. [They are] small and easy to transport — just throw in the range bag. Yet, they are big enough to keep around your neck out of the way[.] I highly recommend them to anybody needing banded hearing protection.” — Tom W.
“Great for woodworkers — These are lightweight AND very effective at reducing noise. When not in use the band hangs loosely around your neck, out of your way completely. Very cost effective for a great product!” — Sheri D.
Quiet Bands Are Much Less Expensive Than Earmuffs
Quiet Band® sound protectors can be purchased online for under $6.00 per set. We like the QB2 Version which comfortable and easy to put in place. These currently cost $5.99 for one set or $11.48 for three QB2 bands with 3 extra sets of plugs. Alternatively, you can get the Leight QB3 Supra-Aural for $5.00 or the Leight QB1 Inner-Aural for $4.96. The QB3 features a flatter ear pad while the QB1 is designed the insert in the ear canal like conventional plugs. We think the QB2 is the best choice for most users.
For QB1, QB2, and QB3 ear bands, replacement ear buds are available and sold by the pair. You can also buy a Ten-Unit Bulk Pack of QB2 Quiet Bands for $45.50 with free shipping. If you run shooting matches or training programs, you can buy these in bulk for your Range Officers and pit workers. And there is a similar Sellstrom Banded unit with blue plugs for just $3.46 on Amazon.

Hearing loss can be progressive and irreversible. If you are a shooter, this is serious business. You need to use effective hearing protection every time you go to the range. Even if you are away from the firing line, gunshot noises can damage your hearing. Good foam earplugs costs mere pennies but they can prevent deafness in your later years. Many folks also wear muffs over plugs. Some other shooters prefer the custom-molded ear plugs. Electronic muffs can be useful when you are away from the firing line because they allow you to converse.
Here are some comments from Forum members on the subjects of hearing loss and the need for proper ear protection. You can join the discussion in this FORUM THREAD:
“If you are young and don’t want to end up with profound hearing loss like I have… ALWAYS ALWAYS ALWAYS use hearing protection. This is from a guy who is social security/medicare eligible, has two Re-Sound aids at a not so cheap $2000.00 EACH… and now has religion! When I was young [we] never wore ear gear and laughed at the ringing after 100 rounds of 12 gauge at the skeet range. Now we live with the consequences. Be smarter than I was!” — Gary0529
“Take it from a 70-year-old that has been shooting 49 years. I now have a Re-Sound hearing aid in the left ear and a Cochlear Implant in my right. I still cannot hear. Custom molded plugs are best. Some are sold at gun shows and some are made by the folks that make hearing aids. They are cheap as compared to this $200,000 implant. DO IT NOW for everyone around guns.” — Richard King, King’s Armory
“Say WHAT? You have to type a little louder! I used to shoot without any muffs, when I was ‘young and indestructible’, and now I have about 40% loss. When I take youngsters and friends shooting, they get muffs and plugs. I’m not allowed suppressors where I live. I would use them if I could.” — Josh B.
“For what it’s worth, I wear both ear plugs and muffs that have NO sound adjustment capability. As a youngster (15) I wore no ear protection either in shooting or motorcycle riding. I kept doing that until entering military service at age 18 where we had to wear ear plugs at the range. Started wearing ear plugs after that, except when motorcycle riding. At around age 53 my hearing started going south as a result of my own stupidity as a youngster and now some 15 years later I only have about 45% of my hearing left. So beware all — there is a price to pay if you don’t protect your hearing.” — Shynloco
“Here are several points to consider:
1. The NRR (noise reduction rating) is determined by “experimenter” fit, not user fit, and trained listeners during the testing period. This results in inflated protection numbers compared to real-world protection.
2. Any disruptions in the protector/skin seal will greatly reduce the effectiveness. Think eye glass temple bars, lots of hair, ear wax, etc. A 5% leak results in a 50% reduction in effectiveness.
3. Double protection gives only 5-10 dB extra protection.
4. Bone conduction gives about 50 dB protection so hearing protectors are the weak link[.]
5. Keep the protectors in/on your ears. Over 8 hours, if you remove them for only 30 minutes (cumulative), the effective protection is cut in half.
So, if you are using a really good muff with NRR of 33 and a foam plug with NRR of 27, the real-world NRR would be about 35 dB, at best. This would attenuate a gunshot by that amount. The key is time versus exposure. Limit the exposure and you limit the dose.” — DelS
“Personally, I use Etymotic Research GSB-15 electronic blast protectors. They are rated at 26-28 dB, but inserted correctly, with the correct fitting tip, approach 38 dB. And, they have a compressor amplifier that allows you to hear soft sounds normally and with very high fidelity. As the sound level goes up, the gain goes down till at an ambient sound pressure level of around 90 dB SPL, the gain is unity, or what comes in goes to the ear canal. However, once the sound level gets to 117dB SPL, the amplifier cannot go higher. So, if you are firing a large rifle with an impulse noise of around 160 dB SPL, your ear only hears 117 dB SPL of that for an effective attenuation of about 40 dB. RIGHT! about the same as the mastoid bone! Can’t get any better than that.
What gives me the right to say all these things? First, a BSEE as well as the graduate course in Audiology and a hearing aid dispensers license. And working in research and product development for the ear the last decade of my career.” — Norm Matzen

Approximately 27,000 suppressors, also called “silencers” or “sound moderators”, are sold in the United States every year. That may surprise you because the main-stream media often incorrectly report that suppressors are illegal. In fact, suppressors are legal to own in 39 states, provided that the devices are acquired in compliance with federal and state laws (which are explained below). In most of those 39 states, owners of legally-acquired suppressors may use their “cans” for hunting. The American Silencer Institute (ASA) has created a graphic showing where suppressors are legal to own, and where they may be used for hunting. Take a look:
SILENCER LEGALITY AND OWNERSHIP
Silencers are regulated under the National Firearms Act (NFA) of 1934, under the oversight of the Bureau of Alcohol, Tobacco, Firearms and Explosives (BATFE). To legally purchase/possess a silencer you must:
Be at least 21 years of age to purchase a silencer from a dealer.
Be at least 18 years of age to purchase a silencer from an individual on a Form 4 to Form 4 transfer (contingent on state laws).
Be at least 18 years of age to possess a silencer as a beneficiary of a trust or as a member of a corporation (contingent on state laws).
Be a resident of the United States.
Be legally eligible to purchase a firearm.
Pass a BATFE background check with a typical process time of 60-120 days.
Pay a one-time $200 Transfer Tax.
Reside in one of the 39 states that currently allows civilian ownership of silencers.
NOTE: In addition to these basic Federal rules regarding silencers, particular states may have additional registration requirements or other regulations. Check with a knowledgeable firearms attorney in your jurisdiction before beginning the process of buying a suppressor.
BENEFITS OF SILENCERS
NOISE REDUCTION
According to OSHA, the threshold for a hearing safe impulse noise is 140 dB. Without hearing protection, exposure to any impulse noise over 140dB causes varying degrees of permanent noise induced hearing loss, which can also lead to tinnitus. Most well-engineered silencers take the dB level of their host firearm well below 140 dB, making those silencers effective primary hearing safety devices. You should always still wear hearing protection (muffs or plugs) when using suppressors.
RECOIL REDUCTION
By containing the explosion at the muzzle, suppressors significantly reduce perceived recoil energy, reduce the rifle’s rearward movement on recoil, and reduce rifle torquing and muzzle flip. The reduction of recoil (and rifle torquing/hopping) lessens shooter fatigue and helps the shooter get his sight picture back on target rapidly after firing. With smaller calibers, a suppressor may enable the shooter to maintain a nearly-continuous sight picture, following the shot into the target. In addition, by reducing felt recoil (and muzzle blast), a suppressor can help inexperienced shooters avoid flinching.
Are sound suppressors useful in competition shooting? In some disciplines, and in venues where sound “moderators” are permitted, the answer is “yes”. In a past edition of Shooting Sports USA eZine, you’ll find an interesting article about the use of sound suppressors (aka “cans”). The article explores the use of suppressors in Europe and in tactical matches in North America. You’ll also find an explanation of the rules and regulations governing suppressor ownership and use in the United States. 
The Risk of Hearing Loss
Three Quiet Band Models
“I first saw these used by Hickok45 on YouTube and he talked positively about them. I got two and gave them a try. At first, I didn’t think they were going to work very well. After some fiddling, I found they work pretty darn good. With my ears, they fit the best if the band starts on top of my head, I insert the plugs then rotate the band behind my head. PRESTO, perfect fit. Shooting the 9mm and 12 gauge out back was comfortable with no ringing afterward. [They are] small and easy to transport — just throw in the range bag. Yet, they are big enough to keep around your neck out of the way[.] I highly recommend them to anybody needing banded hearing protection.” — Tom W.
