Silent, but not too silent. |
Silencers
do not silence a firearm. Silencers are
better named “suppressors” as in “noise suppressor”. Despite what we’ve been taught by movies and television—who
rarely, if ever, get anything wrong—a suppressor will not change a gunshot to a
sound like popcorn popping, or make that cool “fftt” noise. Depending on the ammunition and the suppressor
used, it will only reduce the sound by around 30dB. Most guns crack off at around 160dB or
better. So a “silenced” gun will still
sound like a gun shooting, just a little quieter.
On
the other hand, modern suppressors no longer use the wipes (physical barriers of
any number of materials meant to trap the exploding gasses) which would
physically touch the bullet and effect the velocity. Reducing the velocity of the bullet will
reduce the range and accuracy—not a lot, but it should be noted. Suppressors now use baffles and spacers which
are machined with such great precision that they tend to no longer have these
drawbacks. In some cases, suppressors can actually increase muzzle velocity, although it’s not very much.
Proper hearing protection! |
So, if
you’re not getting James Bond-levels of assassination silence, what do you get
with a suppressor? First, dropping the
dB from 160 (which is dangerous) down to 130dB definitely saves wear and tear
on the eardrums, especially if they're unprotected. It also cuts down on noise pollution for those
areas around gun clubs and hunting areas where gunshots are more likely to be
heard. Aside from the noise, suppressors
also cut down on the recoil as the lighter mass of the gas is slowed and
expelled over a longer period of time. Finally,
you increase your ability to communicate if your ears and theirs aren’t ringing
from the sonic boom of a gunshot, and your voice isn’t being drowned out by
louder-than-a-rock-concert noises. For
military operations, this is incredibly desirable for obvious reasons of
tactics and on-the-fly orders.
One
final note is that suppressors wear out over time. If we’re talking about an older unit, which
uses the wipes, they wear out pretty quickly as the bullet is literally tearing
through them. But even more modern
suppressors are worn down by the corrosive gasses and the passage of the bullet
over time. Automatic weapons are
generally never suppressed for this reason, as the suppressors simply can’t
stand up to the wear and tear. Some of
the highest quality suppressors may last over 30,000 rounds.
