That Hollywood reinterprets the reality and what we are clear, but we like. Although the silence the sound of a gun with a rolled towel or put a pad in front of the barrel as does Toni Soprano, the acoustic cast us not ever.

The noise level of a shot gun without a silencer is around 140 or 160 decibels (which can cause permanent damage to the ears), while if you put a silencer, the noise decreases only up to 120 or 130 decibels . This noise is equivalent to a jackhammer (able to cause you damage your hearing if you're close enough).

need to reduce the length of muffler sound. It's pure physics, but can make some tweaks to increase capacity.

The shot noise comes from three different causes:

1. The detonation, which is the combustion of gunpowder and is the main noise. That is eliminated or reduced with the use of silencers.
2. The breaking the sound barrier . For this subsonic ammunition is used and integrated sonic suppressants. The
3. automatic weapon. They are metal parts that move and make noise.

Using a supersonic ammo silencer reduces the sound but not apaga.Usar subsonic without silencer reduces the sound too, but it would be best to use subsonic ammunition with a silencer.

I leave you with a couple of videos to illustrate the topic.
