Silencers? In fact, they do not exist!


Many people know almost nothing about silencers for the rifle weapons. All of their information in this matter is gleaned from numerous films and computer games.


The silencer never suppresses the sound of a shot completely. The ideas of many ordinary people about such a device and its operation are based primarily on the work of sound engineers. Many imagine a shot from a weapon with a silencer as a barely audible sound, but this is nothing more than a sound effect. Real silencers for small arms are devices that really reduce the sound of a shot by several tens of decibels, but far from completely, protecting the shooter from the sound of a shot, first of all.

About the silencer


The classic weapon silencer is a special muzzle mechanical device that can be used with various models of small arms. The silencer is attached to the barrel, or is initially an integrated part of the design of small arms. The main purpose of this device is to attenuate the sound of a shot, while at the same time the silent shooting device (PBS, an abbreviation common in Russia) also hides the flame of powder gases, which complicates the process of detecting a shooter and does not attract additional attention to it.

The latter is especially true for the military, as ordinary hunters in the woods or amateur shooters at the shooting range do not need to hide. But the military, when conducting military operations at dusk or at night, is more afraid not of the sound of a shot, which is uninformative in the dark, but of bright flashes and sparks. From the flashes of a shot, the shooter can be very easily detected, and he will quickly turn into a good target for enemy soldiers. Therefore, for the military, it is the concealment of the flame of powder gases during firing that is a much more useful function of all silencers.


Sectional silencers

At the same time, such a device has other useful qualities, for example, increasing the accuracy of fire. Experts note that both the machine gun and the rifle with a correctly installed silencer demonstrate better accuracy of fire than without such a device. At the same time, the return of weapons is also reduced. All this together makes PBS very popular in the civilian market in countries where their sale is allowed.

A classic silencer most often looks like a hollow cylinder made of various metals: steel, copper or aluminum, in some cases shockproof plastic is used. Inside such a cylinder, designers placed special chambers designed to remove powder gases. In the vast majority of cases, the silencer is screwed to the end of the barrel of a small weapon using a thread specially made for this.

All types of silencers, including those integrated into the weapon design, reduce noise, which is the result of a shock wave of an ignited charge, which creates a force that pushes a bullet out of the barrel. At the time of the shot, the resulting gases enter immediately into several chambers located one after another inside the muffler. In these cameras, they lose speed, while expanding and cooling. Due to this, the gases exit the muffler, significantly losing their speed.


Silencer or suppressor?


Nowadays, not everyone agrees with the very definition of a silencer (English silencer), for example, the term “suppressor”, which some experts consider to be more accurate, has gained popularity in the world. From the English word suppressor (translated as "suppressor"). At the same time, in many countries, devices for reducing the sound level of a shot are allowed for sale even on the civilian market. For example, such devices are allowed for free circulation in 42 US states. At the same time, in Russia at the legislative level, any devices for silent shooting are prohibited for sale on the civilian market.

Quite a lot is said that the “silencer” is not the best term for designating devices for silent shooting. For example, one of the episodes of the very famous American popular science program “Legend Destroyers” was dedicated to debunking the layman’s television performance about such devices. To do this, they used weapons chambered for .45 (11,34x23 mm) and a 9 mm pistol. Three shots were fired from each weapon sample, recording sound with the help of a professional sound engineer, a specialist in the field of acoustics. The experiment was carried out using devices to reduce the sound of a shot, and without.

The experiment showed that the sound of a shot from pistols without the use of suppressors is 161 dB, and when used, it is reduced to 128 dB. At the same time, the recorded difference of 33 dB is a very significant amount, especially for human hearing, such a reduction in noise makes the sound of a shot safe. At the same time, a normal conversation at a distance of a meter from a person is fixed at 60 dB - this is the basic value of the relative volume. At the same time, the 128 dB that was recorded when shooting using a suppressor is really quieter, but at the same time 115 times louder than the basic conversation of two people located one meter apart from each other.


The experiment showed that a person will hear the sound of a shot from a pistol with a silencer as clearly as the interlocutor talking to him, at a distance of 34 feet (10,36 meters), that is, at a distance comparable to the width of a multi-lane city street. Without a silencer, the distance of excellent audibility will increase to 50,5 feet or 15,4 meters.

At the same time, any silencer is not a tool for killers and not a virtually silent device, but it was such an image that was formed thanks to the cinema. In fact, the military and law enforcement officials love such devices for four main reasons: the extra weight on the barrel reduces recoil and rejection of the muzzle upward, which means the arrow is easier to aim and keep the target on the fly; the device also significantly reduces noise, making it safe for the shooter; reduces bullet deflection and completely removes the flash from the shot. Together, all this makes small arms safer, more reliable and easier to use.

Key benefits of using a suppressor for the shooter


As we have already found out, suppressors are of interest to the military primarily as devices that remove the flash and increase accuracy. For ordinary users of small arms, increasing shooting comfort by reducing recoil is also important, but the main advantage and advantage of all suppressors is the protection of the shooter's hearing. For hunters and amateur shooters - this is the main advantage, which many of them do not even know about. Moreover, it is the loud sound of the shot in 2/3 of the cases that leads to a weakening of the hearing level of hunters and shooters, leading to hearing loss. And, for example, in athletes-shooters, doctors record a sharp increase in cases of neuritis of the auditory nerve.


Using a conventional rifle while hunting, we doom ourselves to very loud sounds of shots - usually more than 150 dB. As you know, everything is known in comparison. For example, the sound of a working jackhammer does not exceed 110 dB, and the sound of a siren in an ambulance hurrying to an emergency call does not exceed 120 dB. Using devices to reduce the sound level of a shot allows you to bring the sound to acceptable values, reducing the noise level by 20-35 dB, most often below the threshold value of 140 dB. This value is the upper safe limit in many countries, for example in Germany suppressors should reduce the sound of a shot to no less than 135-137 dB. So the noise level of 160 dB (a shot from a hunting rifle close to the ear) is able to bring a person into a state of shock, the consequence may be a rupture of the eardrum.

Numerous studies speak of the impact of the sound of shots on hearing, it is no coincidence in the shooting range and shooting range, as in competitions, many shooters use individual hearing protection (headphones or earplugs). Shooting without such devices after a certain time can lead to hearing loss, and in the future - to deafness. At the same time, the vast majority of hunters do not use hearing protection even in countries where it is absolutely legal to purchase devices to suppress the sound of shots. They argue this by the need to better hear all the sounds and what is happening around them in the forest. Surveys show that up to about 80 percent of hunters never use hearing protection.

The decision is not the most far-sighted, since numerous modern studies tell us that for every 5 years of hunting, a person has a 7% decrease in hearing acuity. The biggest problems for hunters are manifested in the perception of high-frequency sounds, notes the Russian Hunting Portal.


The use of suppressors in the hunt

At the same time, the use of modern suppressors can reduce the sound of a shot by several tens of decibels. This allows you to reduce noise to such an extent as to compare the effectiveness of such devices with the effectiveness of an ear plug or headphone. It is not difficult to notice that what we all used to call a silencer is actually not such a device: the sound of a shot only decreases to a level that is safe for the shooter's hearing. The sound of shooting from small arms is never completely eliminated.

In addition to safety for the shooter's ears, modern suppressors or gunshot suppressors have another advantage. Many shooters notice that firing weapons with a suppressor is more comfortable for them. According to their impressions, the level of return of weapons falls by 20-30 percent, which is a very significant amount.

All this together tells us that suppressors have a very good future, despite the fact that they are banned in some countries. Despite the existing restrictions, the market for such devices is growing and experiencing a real boom, which is demonstrated by numerous arms exhibitions. This does not seem surprising. In some countries they have already been allowed to use during hunting, and they help beginners to overcome the fear of a shot when a person instinctively closes his eyes when pressing the trigger. But most importantly, such devices protect the hearing of hunters, shooters, and hunting dogs well: let's not forget about our smaller brothers.

            Have you forgotten to make holes in the bottle?
            In the film, this moment is missed (it is possible that the children would not indulge so). You need to make a bunch of holes in the side walls of the bottle with an awl. Without this, the muffling effect is weak.

          Yes, many more questions to the author ....
          normal conversation at a distance of a meter from a person is fixed at 60 dB - this is the basic value of the relative volume. At the same time, the 128 dB that was recorded when shooting using the suppressor is really quieter, but at the same time 115 times louder than the basic conversation of two people,

          If the difference is 68 dB, it will be 2512 times and not 115.
          Experts note that both the machine gun and the rifle with a correctly installed silencer demonstrate better accuracy of fire than without such a device. At the same time, the recoil of weapons is also reduced.

          A causal relationship suffers. It is a reduction in returns that improves accuracy.
          But if you shoot from the machine .... The silencer, like any compensator and flame arrester, disrupts the flight of a bullet.
          Many shooters notice that firing weapons with a suppressor is more comfortable for them. According to their impressions, the level of return of weapons falls by 20-30 percent, which is a very significant amount.

          What happens with bullet energy?

                  So after all, the article is not about silent weapons, but about devices that reduce the sound of a shot to comfortable, so as not to get an ear injury. Although, in my opinion, the topic of the article does not match the title.

                      In general, rifles always have an individual stock and butt in sports. But there the weight distribution does not fluctuate much, in the literal sense, the horseradish barrel twitches there, and the pistol can hardly be pulled without weighting, there are exceptions, such as the MTs-440, but the exercise is such that it doesn’t matter, and the store is like a Mauser in front of your fingers

                        About biathlon, you should at least look at where those who keep stores at the same vintars. Here they have a strictly individual bed, although it is with a high-speed weight distribution that it is unimportant, but the grip is hyper-essential there.
                        And they are settings and are good and bad at the same time. Moreover. some things are not tuned, but sharpened, for example, a descent with a joint and not with a pillow - a hook and a handle on a pistol or a bed on a screw are sharpened. and the trunk doesn’t walk nichrome, it’s bad for the army - descent with the joint, and for the bullet, since it’s used)))

      Especially for girls with blond hair:
      - if the return decreases, the impulse decreases;
      - if the impulse decreases, then the bullet speed decreases;
      - if the speed of the bullet decreases, then its energy decreases (squared).

        If the return existed only from the fact that the expanding gases push the bullet in one direction and the rifle in the other, then in this case there is a controversial statement. There are machines with a biased recoil momentum, where after the first shot the recoil arrow may not feel at all. The recoil force is also affected by expiring powder gases, which can be directed not forward, but into the walls of the muzzle brake and thereby reduce recoil without reducing the speed of the bullet.

          Secondly, the return, almost completely, can be extinguished only on "reactive" barrels, such as: recoilless guns, a grenade launcher, when a reverse impulse is formed, due to the mass of gases thrown back ..

                If the muzzle brake is of a reactive type (redirects powder gases in the opposite direction), then of course you can’t apply this principle to the silencer, but the active one has the main effect of a gas blow to the transverse partitions. In the silencer, while gas fills one chamber, the bullet will go to another, and so on. What problems?

                gas is simply pushed between the partitions, slowly dissolving in both directions. There was also a figure: 1g of gunpowder per 1 liter of volume

            You contradict yourself: "active type brake" - "without reducing the speed of the bullet."
            In fact: energy is spent (diverted, dissipated) on brakes, compensators, silencers ... and therefore the energy of the bullet is reduced. This is without taking into account the dynamic resistance of these devices.

              All of these devices are located behind the cut of the barrel. That is: the powder gases are no longer dispersed by the bullet, which means that they are not redirected to other devices on its energy .. And even more, when the bullet leaves the barrel, the gas pressure behind it is very far from atmospheric and enveloping the bullet affect the accuracy of the shot . Muffler baffles reduce the time that these gases act on the bullet, and therefore can increase the accuracy of the shot.
              Of course, it is necessary to shoot weapons with and without a silencer separately.

    Yes, many more questions to the author ....
    normal conversation at a distance of a meter from a person is fixed at 60 dB - this is the basic value of the relative volume. At the same time, the 128 dB that was recorded when shooting using the suppressor is really quieter, but at the same time 115 times louder than the basic conversation of two people,


    If the difference is 68 dB, it will be 2512 times and not 115.

    O_o, my God, where are such wild numbers from both the Author and you ??? Definition more в *** times is a multiplication, more on *** This is addition.

      A decibel is not a linear, but a logarithmic (power) unit. The addition of degrees gives a multiplication of the result. An increase of 1 decibel for sound means an increase of approximately 1,122 times. At 68 decibels - 2512 times.

      Logarithmic value from the "zero" level. Something like this: 10dB - 3,16 times. 20db -10, 30 - 31,6, 40 - 100, etc. Accordingly, the difference is 68 dB (so as not to bother with counting or searching for tables, let's take 70) this is 3160 times. With a calculator (according to the tables) 68dB may well be in 2512.

    Does the author think that “sound suppressor” and “silencer” are completely equivalent terms in terms of content?
    Not "noiseless," after all.
    In addition, it would be worth mentioning the main sources of the sound of the shot, and this is not only the sound of expanding powder gases, but also the shutter clang (often quite loud), and the click of the movement of a supersonic bullet.

    Experts note that both the machine gun and the rifle with a correctly installed silencer demonstrate better accuracy of fire than without such a device.
    What? All my life, on the contrary, it was - Glushak reduces accuracy, therefore it is used only in peak cases, the explanation for this is generally as simple as firewood ... Do you know that, for example, a slotted DTC reduces accuracy? Whenever a bullet passes the gap, the barrel twitches. In the PBS chamber, it’s even more fun - the bullet came out, followed by gases, they run even faster, not only is the plug a little bit - but always asymmetrical, they still act asymmetrically on the bullet.
    Do not forget, the slower the bullet - the more the wind affects it, and by the way it is always uneven and unstable at a distance - that means subsonic - well with PBS - the spread on the same barrel will always give more.

            Afterburner. Somewhat not the same, almost, but there is a difference. By the way, the author correctly said that in the Donbass, everyone who could - put out afterburners, artisanal, yes)))
            Tfu ... There is a higher topic in this thread about PBS and PMS. Almost answered this. This is an afterburner, it is for other purposes, and there the whole circuit of the machine is sharpened so that it won’t succeed in jerking for a double shot plus a balancer, including this one, like mosya without a bayonet and with a bayonet - it shot differently.

      This reduces recoil, respectively, when firing bursts and increases accuracy. Similarly, reducing the accuracy of the DTK on the Ak-74 is standard, and not at all for “peak cases”. Obviously the effect of reducing accuracy is small compared to the accuracy of the weapon itself.

        To begin with, you initially mixed PBS with something. PBS is a silent firing device, it is used ONLY with a subsonic cartridge. For a simple reason - if you do not stop the sound, the SUPER sound bullet at the exit from the barrel will cross the sound barrier, the so-called “jump” - the pop is almost cooler than a shot. In fact - the same explosion - there is a shock wave. Listen once, as the plane switches to supersonic.
        For PBS, I said all right.
        For regular, supersonic, there is PMS, this is not about women, but "low noise". By the way, it seems that the author has beguiled. PMS is designed specifically for automatic fire.

        automatic tactical muffler

        For automatic fire in general, plus or minus half a bast shoe for accuracy ... Not significant. And nevertheless, if you clamp it into the machine - the accuracy with and without PMS will be lower with a glider. For automatic shooting - this is not the point, but single you will have a dispersion harder. Non-capturing will succeed.

    Do not like the "silencer" use the "suppressor". "Suppressor" in Russian is more understandable than "Suppressor"
    Or is it time for us to completely abandon Russian?

    As we have already found out, suppressors are of interest to the military primarily as devices that remove the flash and increase accuracy.
    The author is completely confused in the muzzle devices of small arms. In order to remove the flash of a shot and increase the accuracy of shooting, a suppressor is not needed and it is foolish to use such a complex and expensive device as such. For this, such combined devices as a muzzle brake-arrester are produced.
    An example of such a device is the closed type Tactics-Tula Noch-2M flame arrester.

    They provide for the suppression of a muzzle flash, lower recoil and tossing of the barrel.

      Silencer or suppressor?
      The device for reducing the sound level of a small arms shot - ПСУЗВ.
      Further we have varieties.
      PMS is a low-noise firing device, sometimes called a tactical silencer.
      Designed to: provide masking the position of the shooter in the daytime and at night by reducing the intensity of the sound of the shot (reducing excessive sound pressure from the muzzle wave during the shot), changing the sound field of the shot, as well as significantly reducing the intensity of the flash of the shot; decrease sound impact on the arrow. The use of special cartridges is not required.
      PBS is a silent, flameless firing device. Used only with special subsonic cartridges.

        All types of silencers, including those integrated into the weapon design, reduce noise, which is the result of a shock wave of an ignited charge, which creates a force that pushes a bullet out of the barrel.
        The main source of shot sound are:
        moving elements of the weapon mechanism;
        projectile pushed air in front of the barrel
        a shot;
        powder gases bursting between the barrel wall and the projectile,
        leading projectile;
        gunpowder gases leaving the barrel after the projectile takes off;
        air shock wave generated in front of the gas flowing from the trunk
        the cloud.

    Wonderful study from the couch!
    "Silencers" (PBS, PMS) "improve accuracy" laughing laughing laughing According to all reports, accuracy drops when using such tools.
    The main purpose of using such devices is to reduce sound (let the author try to shoot from a machine without protection or PBS in the room), and plus to reduce the rumble is the absence of flame. These two positive factors are considered more important than the reduction in accuracy at short distances (at which fire contacts usually take place in rooms and towns). But thanks for the article. He laughed. good

    At one time, the brother-in-law asked to make a silencer for a small-bore pistol: the sound of a shot is loud, and most importantly sharp, there is not much work to do. Made from the housing of the old Soviet pump for bicycles, inside the housing from starters for fluorescent lamps (fluorescent). It turned out to be an easy silencer, it worked well, at ten meters you hardly pay attention to a shot - it’s just not sharp “fluff”.

    Good article! good I liked, although not with everything written in it, I agree!
    I never used a silencer and ear protection when firing (which I now really regret — it was a real mistake!), Except that the headset in the tank was fired from a cannon and a coaxial machine gun.
    Therefore, already in my youth I felt the deterioration of my "super-sharp" (after all, before that I had "selectively" heard everything said by someone, even at the other end of a sleepy reserved seat car, on the train smile ) "hearing, almost ceased to perceive the" upper frequencies "in the speech (as stated in the Article) and my wife laughed kindly, calling me a" deaf teter "! smile
    Especially, it happened that I suffered from a common fire precisely from the AK-74 (because of its "sonorous and piercing" sound, "beating on the ears" - then I had it for a very long time, for weeks, hurt unbearably), but our AKM had a very "slight" sound of shots! However, all this was already thirty years ago, even under the Union, but the consequences of the "mistakes of youth" especially "go sideways" to old age and, no, no, they inexorably remind of themselves ....

    I do not agree about increasing accuracy when firing with a silencer.
    Indeed, even the super-coaxial axis of the barrel channel (which is unattainable in real life!) Installed, the silencer creates significant distortions in the “period of after-effects of powder gases” on the bullet (not to mention the fact that the real “non-theoretical” bullet is furiously rotating punches-pushes the rubber membrane of the "chamber" and, as often happens, slightly touches itself for the "turbulent" partitions inside the "PBS" working chamber, and in the "integrated" silencers the bullet movement is aggravated by the "picture" of gas pressure jumps in erforirovannoy "the barrel, even if they" weep holes "drilled properly, especially at the bottom of the grooves, not according to their fields, and do not create a pool of tangible" friction "interference)," so that when viewed objectively, using a silencer, the spread of bullets in the target increasesalas! request This is one of the negative "side effects" of the use of silencers and real specialist gunsmiths and experienced shooters, of course, they know about this! winked

    Although the positive effect of weighting the muzzle of the barrel is present, but the presence of such an “abnormal load” for pistols with automatic equipment “short barrel travel (various types of locking-lever, skew or rotation of the barrel, etc.)" -usually a muffler reduces the reliability of the self-loading pistol (about special self-loading "silent pistols" with other principles of silencing the sound of a shot, for example, our MSS, in this case we are not talking)! yes

    Mention of another (also long-known) curious kind of silencers, an open "pipe (like ejection cooling the barrel in a Lewis machine gun)" - completely without partitions, with the ejection principle of reducing the sound of a shot, did not meet at all in this Article.

    Interestingly, the author at least once CAM shot a weapon with a silencer and without? Reduces returns? With the weight of an assault rifle or a rifle 3-4 kg, what kind of a fool should be attached to the barrel, so that by increasing the mass, to reduce the return? Confused silencer and DTC, whose function is to reduce the return, it is strong. Nonsense at the compilation level on some popular science sites. Author, I regularly shoot with a silencer and hear only the shutter sound on the semi-automatic rifle.

    60 dB is the baseline relative volume. At the same time, the 128 dB that was recorded when shooting using the suppressor is really quieter, but at the same time 115 times louder than the basic conversation of two people located one meter apart from each other.
    128dB is louder than 60dB at 2,1333 ... times, well, or at 68dB if you like. Where did the 115 dB figure come from?

    I never read about an interesting effect: the sound from the muffler goes like a narrow beam of a flashlight, not more than 10 grams. I can’t hear it from the side, but along the line of the shot - fine! Therefore in the field
    just a small click, and in the forest only twice as quiet as a regular shot. The sound between the trees starts to jump.

    Article is some kind of nonsense
    In fact, the military and law enforcement officials love such devices for four main reasons: the extra weight on the barrel reduces recoil and rejection of the muzzle upward, which means it is easier for the shooter to aim and keep the target on the fly; the device also significantly reduces noise, making it safe for the shooter; reduces bullet deflection and completely removes the flash from the shot. Together, all this makes small arms safer, more reliable and easier to use.
    reliable and simple? The author you just wrote a set of words. PBSs or "Glushaki" are used for their intended purpose, they reduce the sound of a shot, not for accuracy or reliability, and that would make it more difficult for the enemy to spot the shot, especially in the mountains.

    What happens with bullet energy?

    Nothing. What could happen to her?

    Especially for girls with blond hair:
    - if the return decreases, the impulse decreases;
    - if the impulse decreases, then the bullet speed decreases;
    - if the speed of the bullet decreases, then its energy decreases (squared).

    Dear Genry!
    Firstly, it’s not very clever to call absolutely unknown people “girls with blond hair”.
    Secondly, if recoil decreases, it means that the recoil momentum is reduced, and not the bullet momentum. And the recoil momentum is changed by all muzzle devices during the aftereffect, that is, after the bullet takes off from the barrel. Thirdly, from here follows - a decrease in the recoil momentum by a muzzle device (by the way, the full name of this class of products sounds like "gas-dynamic muzzle devices" - so, as an educational program) does not affect the speed of the bullet.
    The only thing true in is that when the initial velocity decreases, the decrease in the bullet energy is proportional to the square of the velocity change.

    Bullet speed is no less important than PBS! The combination of PBS and bullets with subsonic speed gives a significantly lower shot sound and fewer unmasking factors! Using one without the other is doubtful, unless it is a desire to shoot without protecting the hearing aid.

    If the difference is 68 dB, it will be 2512 times and not 115.


    Most likely, in the television program, measurements were also made on the absolute volume scale.
    And the absolute scale of volume is a scale of subjective perception. And there, for every 10 dB of change in sound pressure, the volume changes by 2 times. Such is the logarithmic feature of human hearing.

    2 ^ 6.8 gives 111, and the difference from the voiced 115 is possible due to measurement / calibration errors and other specifics.

    The article is interesting, in terms of PBS, but I do not agree with the author regarding his statement "The sound of shooting from small arms is never completely eliminated." But what about a special silent weapon under a cartridge, in which a silent operation is achieved by locking powder gases in the cartridge case? There, too, a sound is heard, but directly triggered by the mechanisms of the weapon (click). The sound of a shot as a result of chemical processes is not there.

    "... by reducing the noise level by 20-35 dB ..." Which, in a more understandable language, means: reducing by 10 - 60 times. "
    A 60-fold decrease in the amplitude of the sound wave (read - air pressure on the ear membranes) is quite significant and with urban daytime noise, the shot will dissolve in them.
    In the film “Voroshilov Shooter,” the speed of the SVD bullet is two and a half times the speed of sound. And the sound from the air condensation will be such ... as from a shepherd's whip, where there is neither gunpowder, nor a shock wave of hot gases. And I heard great. That’s why now special ammunition is used with a bullet take-off speed of up to 320 m / s (with a standard atmosphere).
