We would sneak up on a large number of rabbits and knock down at least half a dozen before any of them had any idea what was happening. I will never forget the confusion of the remaining rabbits as one by one their companions just fell over alongside them. The difference is a 22 subsonic is 68db for CCI Quiet even a 10db efficient suppressor will make a sound no louder than a conversaton, a subsonic is around db times louder a 30db suppressor would reduce it to the level of a power lawn mower, motorcycle, farm tractor, jackhammer or garbage truck.
That 68 decibel rating from CCI is simply false. Daniel is correct, and unfortunately, the ATF is currently smashing down his door and tearing apart his home like the SS looking for Anne Franks. In Army Basic Training, I would be rotated through marking targets on the rifle range.
We would be within about six feet of the target center protected by a dirt berm. The CRACK of the bullet passing through the paper was painfully loud, more so than the actual noise of the weapon firing.
No way to silence that! I spent a good part of my life doing exactly the same thing redstick, usually with. Even putting a silencer on a. I know the sound, I was in the Marines. I have had many years employing different types of suppressors and suppression techniques, on a variety of targets at close range, when noise was a factor in my survival.
Suppressors CAN be made to fire at decibel levels that will leave the misses in the next room sound asleep. With the use of dampening objects to slow the bullet below sonic speeds i. I know this because I know this. Measurements of loudness are meaningless without an accompanying reference distance; the typical reference distance used is one meter. For example, an ambulance or police siren is typically — db measured at a distance of 1 meter from the siren.
Loudness behaves according to the inverse square law: as the listener get farther away from the source of a sound, the loudness decreases proportionally to the square of that distance. Hi, I have. That bullet has to come down somewhere.
Daniel, what you are describing is a trip to the federal country for about ten years. With only a couple uncommon and very low-powered rimfire rounds as the exception, no gun is safe to shoot without hearing protection. Almost all guns make dangerous and damaging noise that can cause permanent hearing loss with a single shot. Suppressors are the only device proven to reduce the sound of gunfire at the muzzle where you need it the most.
All other forms of hearing protection only mask the sound to the person wearing it. A silencer reduces sound for all around the gun. This is invaluable when hunting, at outdoor ranges where a reduction in noise pollution is desired, or in a personal defense situation. Silencers are sound pollution-reducing devices.
Think of them as mufflers for cars. His company is still in business today creating technology for reducing noise pollution. If you look at our gun silencer decibel chart, you see that every time you use a silencer, you reduce the actual sound to hearing safe levels.
Nothing else can do this, because silencers effectively muffle the gas of firing at the muzzle , and slow it down to make the shot quieter. Gun silencers are safety devices intended to reduce the real noise of shooting and protect the hearing of the shooter and people around the shooter. However, larger calibers such as the. The sound of a gunshot travels quite long distances.
How far a gunshot can be heard will depend on the ammunition, the firearm, as well as the weather and temperature. The gunshot from a suppressed firearm will be more silent.
Silencers reduce the range you can hear a gunshot to meters. There are several ways you can ensure hearing safety in environments with hazardous noise levels. Hearing protection is an efficient way to dramatically reduce the sound of a gunshot. Special shooting hearing protection is designed to reduce noise levels to under dB.
All hearing protection solutions need to specify the NRR level. The higher the NRR level, the more decibel reduction the gear provides. Most shooting earplugs and earmuffs have NRRs between 15 - For indoor shooting, you should use hearing protection with a NRR between 28 — As far as sound measurements are concerned, we can cite decibel dB levels all day, but unless we have something to compare them to, the numbers are somewhat useless.
With this in mind, we set out to do our own independent sound level testing. We wanted to approach our project as scientifically and accurately as possible, without first having to get a degree in acoustics. We recorded both suppressed and non-suppressed readings, using the z-weighting method of measuring high pressure levels. This method of measurement is also referred to as linear or unweighted. Unweighted is a more accurate method of evaluating potential hearing damage and is the best method to use when testing firearms.
Following these standards , we placed the microphone 1 meter to the left of the muzzle and 1. All testing was completed away from any reflecting surfaces, as to not negatively affect the audio readings. We compared five of the most popular handgun and rifle calibers available on the market today, testing 30 different SKUs of ammunition in the process. Then, we test fired five rounds suppressed and three unsuppressed with each brand of ammo to find an average dB level.
The first shot out of a suppressor at any given time will generally be louder than the subsequent rounds fired. This is caused by the burning off of oxygen that has filled the silencer baffles and chambers when the action is left open or the device has not been in recent use.
With FRP in mind, we wanted to gather more testing data to find an average suppressed level, compared to our test shots when firing unsuppressed. Three of the most popular rifle calibers are.
We chose two different barrel lengths as one of our test variables, one shorter and one longer. As expected, this smaller load had some of the lowest dB readings for the rifle calibers. The lowest average suppressed measurement of Overall, we recorded an average of dB when firing all ammunition suppressed. These levels are comparable to the sounds you would experience when operating most power tools. When shooting unsuppressed, this smaller caliber comes in at an average of dB, just slightly louder than the suppressed.
When shooting with a silencer, the levels come in at an average of dB. We observed a change of only dB between the two barrel lengths, both suppressed and unsuppressed. Of all the rifle calibers tested, the loudest average unsuppressed measurement of OTM ammo.
The same ammunition fired with a suppressor came in at an average of While it is a reduction of almost 25 dB, the sound of a suppressed. We tested three of the most popular pistol calibers, 9mm, 45 ACP, and. Similar to the rifle testing,. The suppressed Sig P conversion gave us an average of dB for all ammo tested. When fired unsuppressed, the. The unsuppressed MP5 registered an average dB, compared to the unsuppressed Glock 19, with an ear-splitting average of dB.
We saw comparable results for 45 ACP as we did with 9mm. The average unsuppressed levels, which were some of the loudest results for the pistol calibers, came in at average of dB, while the average suppressed levels came in dB lower, ranging from dB.
Both firearms used for testing in this caliber did have the same barrel length of 5. Silencer dB Level Test Data. There are a lot of reasons for owning a silencer. Some may be about personal rights, others might just be looking for another hearing protection alternative. Whatever the reason may be, educating yourself and others will help everyone better understand how these devices, and their potential role as everyday tools, can have an influence on our hearing health, personal defense, and recreational uses.
So where do you stand on the topic?
