HOW SILENCERS WORK Firearm silencers work in the same manner as mufflers for cars
and lawn mowers. Both provide a controlled environment in which the gasses can expand and cool before exiting into the
air with less energy and noise.
A typical silencer has a casing segregated into chambers by partitions called baffles. Each baffle has a passage through
which a projectile can pass. When the host weapon is fired, the projectile exits the barrel and passes through the length of
the silencer, but the gases that propel the projectile expand into the baffled chambers where they are temporarily trapped.
When they do find their way out of the silencer, the gases have slowed considerably and thus produce less sound.
