HOW GUN SILENCER WORKS.......HOW TO MAKE A GUN SOUND LESS

Hello friends,

         Today we will know how gun silencer works. You must have seen on movies that someone with a gun (which looks a little bit long) kills someone without any loud noise. It may looks so scary for the one who’s dying but you must have enjoyed that moment. When hitman kills someone so smartly & silently, we feel like “yeah”. So why that gun was not sounding much louder, I know that, you know it was a silencer who was slowing down sound density. But ever thought how??How a small device compress that louder sound to a little whisper like sound heard from some feet away. If you want to know this answer, then you are on the right place .let's know…..

So first thing let me clear you that actually it’s not silencer, it is suppresser. The name is suppressor because the obvious reason is it supress the louder sound. Now according to some gun developer’s gun actually make 3 kind of sound. The first sound when it hits the bullet, then when the explosion gases expands and the 3rd sound is called ballistic crack sound.

Now the first sound is when hammer hits the bullet, it actually doesn’t makes a louder sound, but it makes a sound. When the trigger is pressed the hammer hits the bullet which creates the first sound, not a harder sound but sound is sound. Now this sound does not needs to be compressed.

Now the second sound is when the explosion volume try to expand. When the gun hits the gun powder it burns & explode, this explode pushes the bullet to catch the speed. During this just after the barrel The explosion volume try to expand which causes that louder sound because that volume don’t find any space to expand inside barrel. So if some space can be provided inside the barrel so that the volume can expand without slowing down the speed. The problem can be solved by expanding the barrel length & makes that length thick to provide some space .That what the silencer do. That extended part is called suppressor/silencer. Suppressor provides some space layer by layer (in different chambers) to allow volume to slowly expand. That’s how a very louder tear falling sound compresses to a whisper like sound.

Now the 3rd sound it’s the sonic boom sound bullet creates when it touches the sonic speed range like a space vehicle. So some manufacture design guns & bullets so that they will not go fast up to sonic speed range.

 The Suppressor/silencer part only compress that 2nd sound which is cause by explosion, it doesn’t deal with other 2 sounds. There are also oil filter suppresser is used. Some guns comes in inbuilt silencer/suppressor And some guns need to screw a silencer/suppressor.


So that was on how silencer works. Also with some extra information. Extra information are good right. I hope you like it….
