Silencers are a greatly misunderstood component of firearms, in large part because of their portrayal in video games and action movies.
Though silencers can greatly reduce the noise of a firearm, they do not eliminate the sound of a gunshot completely. Instead, silencers limit the noise to a hearing-safe level, keeping a firearm’s burst below 140 decibels.
A pistol equipped with a silencer, for example, is slightly louder than a thunderclap — while being a tad quieter than a dish breaking.
The main benefit of silencers isn’t in the element of surprise but in helping to reduce hearing damage. Hearing loss is the most common disability claimed by veterans.
