My answer may (most likely) won't be correct. If a silencer is on a gun it's gonna make you a silent killer. So say you were to go out hunting. You shoot, there's no noise, so you don't spook the animals and they don't know what's coming. Verses having a gun with no silencer the noise of the gun being fired would echo through the woods and spook off any close and far targets.
A gun silencer the rapidly expanding gas makes when a gun is fired A silencer screws on to the end of the barrel and has a huge volume compared to the barrel (20 or 30 times greater). This allows the Pressure behind the bullet to have a larger space to expand into. So the pressure of falls significantly. Therefore, the sound of the gun firing is much softer.
Haha yeah i kinda get that part, i went bow hunting a couple of times before... but i would like to know the science part behind a silencer... thanx anyway!!
I think it would still spook animals. I've heard silenced guns, you can still hear them, it's just muffled. But it certainly wouldn't go as far.
I'm pretty sure he meant like, how does it silence the gunshot. But you're right.
