How does a gun silencer work? It seems the noisy part would be on the back of the gun where the hammer hits the bullet, not where the bullet exits. (I know nothing about guns)

There is no such thing as a silencer, they only exist in movies. Suppressors are what make a gun quieter, not silent. When a round is fired the gases behind the round push the round out the barrel. The round and the gases behind it come out the barrel. With a suppressor the round passes through without being impeded followed by the gases. The gases are redirected through baffles which slow down the gases. The suppressor is also made from a metal alloy which disapates the heat of the gases.
The end result is the gases are cooler, moving slower, and less pressure when they exit the suppressor.
There is still a loud noise that can be heard by everyone around. If you try to fire a .44 with a suppressor indoors, but without earpro, you are going to have a bad day
