We'll debunk the myth created by Hollywood that a firearm can be completely silenced, reduced only to a "pew". I'll pull together some examples of silenced firearms and show what silencers/suppressors can and can't do, and compare the noises you'd get to some other types of sound. Then I'll go into the components which make up firearm noise: mechanical, sonic boom, and muzzle blast. Then I'll discuss the advantages that silencers bring, even though they're not as impressive as they seem in the movies. Finally, I'll sum up by discussing the limitations of silencers and why they are not universal. from Silencers: not very silent [Military Realism]
