Traditional measures of suppressor noise reduction have focused on the change in the peak sound pressure level between suppressed and unsuppressed conditions. Because of the MIL-STD 1474D, the ability to reduce the suppressed level to below 140 dB peak sound pressure level (dB pSPL) was the goal for firearm suppressor manufacturers.
Combined with firearm sound suppressors, subsonic ammunition may significantly reduce sound levels compared to normal ammunition. [4] Specific reductions depend on the ammunition and suppressor. The peak sound pressure levels of a Remington 700 .223 caliber bolt-action rifle firing high-velocity (supersonic) ammunition using a GEMTECH G5-5.56 ...
The decibel rating level is 25dB. The Wind Talker can be mounted to any rifle with either a 7.62 mm or 5.56mm bore diameter as long as it utilizes a Vortex flash hider. The Wind Talker sound suppressor is in the military inventory system as NATO Stock Number: NSN 1005-LLL-997965, utilizing the same NSN number as the M14DC which it replaced. [1] [5]
Firearms fitted with SilencerCo suppressors. Sparrow 22, which is compatible with multiple calibers up to 5.7×28mm and rated for full-auto fire. Warlock 22, a .22 LR silencer that weighs 3.0 oz and reduces sound to 114.6 dB. Spectre 22, which handles a range of ammunition from .22 LR to 5.7×28mm.
Sound exposure level (SEL) is a logarithmic measure of the sound exposure of a sound relative to a reference value. Sound exposure level, denoted L E and measured in dB , is defined by [ 1 ]
This due to the requirements of US commercial customers who must procure a different Bureau of Alcohol, Tobacco, Firearms and Explosives tax stamp for each silencer they own. [5] Their first silencer was the Sandman series. [3] In 2018 Dead Air introduced Key-Mo, an adaptor which allows the use of Silencerco silencers with Dead Air muzzle ...
The PBS-1 silencer, designed for use with the AKM to reduce the noise when firing, was introduced in the 1960s, and was used mostly by Spetsnaz forces and the KGB. [3] [4] [5] They were used by the Spetsnaz in the Soviet–Afghan War in the 1980s, requiring the use of the AKM (modernized variant of the AK-47), because the newer AK-74 did not have a silencer available.

Its noise levels are similar to those generated by .22 LR match ammunition. The weapon is fitted with a special .308 Winchester/7.62×51mm NATO 406 mm (16 in) long barrel which has a twist rate of 229 mm (1 in 9 in) and an integral suppressor. The aluminum alloy integral suppressor is fitted over the barrel and can be removed by the user.
