“Shhhh” – Quiet the Rifle

Mike Jones is back (and this time… he’s suppressed!)

Just a 20 minute jaunt into looking at fighting rifle suppressors which are, like optics, carry guns, hunting rifles, ammunition, and everything else, something that are purpose built for their intended use.

While the video takes it down a bit of a Fall-out apocalyptic things are really bad outside vibe, for practical reasons suppressors are very good things. When it comes to home defense, shooting a rifle in indoor spaces with super sonic rounds, taking that initial edge off the muzzle by several decibels, usually between 20 and 30 which approximates what ear plugs do with their NRR shielding. A solid decibel reduction is important but the overall endurance of the suppressor and repeatability of both high volume fire and consistent reduction across a variety of atmospheric mediums (humid vs dry, hot vs cold, shorter and longer barrels)

Second consideration is additional wear and tear on parts by changing the pressure the weapon is working with. Many designs, like the Surefire, OSS, and Deadair M, take all of the above into consideration and instead of delivering a ‘quiet’ design they delivered a durable design that still significantly reduced both visual and audible signature.

Keep in mind the 10 decibels is a power factor of 10, a logarithmic and not a linear scale. A suppressor that shaves 20 decibels is reducing the power factor by 100. One that consistently does 30 is reducing it by 1,000. Amplitude is 10 for every 20 decibels, so a suppressor that does 20 reduces the power by 100 and the amplitude by a factor of 10. Those are significant reductions to both your ears and allied ears, as the nearest individuals, and much more significant the further from the sound source you get. Remember that sound travels spherically (4/3 Pi^3) and reduces in strength at that rate. That’s why a rifle next to you is painful to hear, but one 10 yards away is much more tolerable despite being essentially still right next to you.

So, pick wisely. Don’t get bogged down on a single aspect. And enjoy.
