Gun silencers and how they workBy Graham and Ben

How they work.

A silencer screws on to the end of the barrel and has a huge volume compared to the barrel. With the silencer in place, the pressurized gas behind the bullet has a big space to expand into. So the pressure of the hot gas falls significantly. When the bullet finally exits through the hole in the silencer, the pressure being uncorked is much, much lower. Therefore, the sound of the gun firing is much softer.

To fire a bullet from a gun, gunpowder is ignited behind the bullet. The gunpowder creates a high-pressure pulse of hot gas. The pressure of the gas forces the bullet down the barrel of the gun. When the bullet exits the end of the barrel, it is like uncorking a bottle. The pressure behind the bullet is immense, however on the order of 3,000 pounds per square inch (psi) so the POP that the gun makes as it is uncorked is extremely loud. The thing that gives away the gun is shooting is when the bullet hits the target.

Why is there noise

The gun silencer invention was made in 1905 by Hiram Percy Maxim after observing the swirl of flushed water in a toilet. He applied the law of conservation of energy to turn the sound energy into heat in his invention.Hiram Maxim is generally agreed to have invented the first commercial silencer. Made of metal, the Maxim silencer fitted onto the end of a pistol and reduced, though did not eliminate all the noise.

Who made the silencer

Thanks for watching.
