Are Suppressors Really That Quiet?

How Quiet Are Suppressors?

While most suppressors are not "movie quiet," they still provide a substantial reduction in the sound and concussive force generated each time a round is fired. The level of sound suppression depends on several factors, including:

  • The type of firearm being suppressed (bolt action, semi-auto, etc.)
  • The caliber of the firearm being suppressed
  • The length of the barrel the suppressor is attached to
  • The type of suppressor (baffled, flow through, integral)
  • The material used to construct the suppressor

Sound is measured in decibels (dB), so many suppressor manufacturers provide a dB rating on each of their products. These ratings can provide insight into the efficacy of a given suppressor when properly installed on a compatible firearm that is loaded with quality subsonic ammunition.

Choosing The Right Ammo For Your Suppressed Gun

Different types of ammunition will also have varying effects on sound suppression. Many standard rounds are supersonic, meaning the projectile travels fast enough to produce an audible "crack"  and will have a significantly louder report.

By contrast, subsonic ammunition enables the projectile to move at slower speeds, reducing the initial sound and eliminating the "crack" so that the suppressor functions more effectively. Choosing the right ammo for your firearm and suppressor is essential in achieving the best sound suppression possible.

What To Expect From Your Suppressor

The average suppressor can reduce sound by as much as 40-50 dB. This change is substantial enough to augment your existing hearing protection and with smaller calibers like .22 LR, may even negate the need for traditional hearing protection altogether.
