How Does a Silencer Actually Work?

Today we're going to take a look at how silencers actually work for all different types of weapons, from rifles to tanks. Check out our new military video where we break down the science behind the ultimate stealth mode for your explosive gun shots, the silencer.

The bois know to put a monolithic suppressor on everything.

Actually you can prevent a bullet from breaking the sound barrier. It is called “sub-sonic” ammunition. Bullets made to intentionally go below Mach-1. Traveling fast enough to do damage, but slow enough to not cause a sonic boom.

“Silencers” aren’t for stealth, they’re primarily for hearing protection. By the way, nobody calls them “silencers” anymore. They’re generally called suppressors, since they don’t actually silence the sound of gun fire.

[JustADioWhosAHeroForFun]

It's not really silent, more like suppressed
That's why it's called a Suppressor

"There is no way to stop the sonic boom of a bullet."
Sub-Sonic bullets: Am I a joke to you?

“There’s no way to break the sound barrier”

AS VAL: “Hold me beer”

Tank: uses a silencer to take out another tank
Terrorists: "must’ve been the wind"

You got me in the first 5 seconds: ‘member Goldeneye.

[aprotogen]

Payday:Literally throws a Molotov, Yells and runs through a bank filled with people
The guards:Hm, must've been the wind.

[PackOfDeritoz]

Who else was annoyed by silencer instead of suppressor

[stormolflak]

"There is no way to not break the sound barrier"
AS VAL: Lol

Me: Subsonic bullets...

This is literally the "Did you put your name in the goblet of fire, Harry?" situation. "Hold on I need to go feed my baby that's quietly screaming for food."

“You would need a silencer the size of a refrigerator.”

The Silencers in Games and Movies go Piew Piew Piew

[bencrampton]

There's a 9mm round, and 9x39 round can be shot at subsonic speed, meaning that guns can be fully supressed with a normal-sized silencers.

"The laws of science will never allow a gun to be completely silent" Maxim: hold my maxim9

Infographics: You see the military ALSO has a silencer for a tactical nuke.
