There are two sources of loud noise to address—first is the pressure wave that is created by the
hot expanding gases and second would be the sonic boom generated if a bullet is accelerated to a
velocity beyond the speed of sound. To address the latter, the propellant load would be reduced
such that the bullet's muzzle velocity does not exceed the speed of sound. To address the
pressure waves, some type of baffle system is used to break up these waves as the gases exit the
muzzle. Such a device can be screwed onto the end of the barrel.
