Suppressors are nice when shooting from enclosed spaces. Especially from a metal box blind

BangBang thanks for the info!
I was very pleasantly surprised that my Osprey45 suppressor on my Springfield 10mm reduces recoil so drastically. It makes my 10mm shoot about like a 9mm (subjective but yes it’s a radical reduction in recoil no matter how you measure it).Hello all, here is today's article posted on TheArmoryLife.com. It is titled 5 Reasons to Own a Suppressor and can be found at https://www.thearmorylife.com/5-reasons-to-own-a-suppressor/.
What is actually occurring is that the spring in the piston (which is inside the suppressor) changes the inertia curve so that the extra mass of the suppressor does not inhibit the action of the recoil driven slide of the firearm. The useful side effect is radically reduced felt recoil. Don’t shoot a suppressor unless you want to buy one because you will be hooked for sure.
One correction. The sound from a shot being fired is measured at a specific point in space. Generally, for firearm, it would be 1 meter, or a multiple thereof to the sound meters's microphone. But it is measured as a point in space and therefore as Sound Pressure Level (SPL) also known as pressure wave intensity. It has been stated that 10dB is ten times the difference. That is incorrect. 10dB = 3:1 SPL. A 10:1 ratio would be 20dB SPL. But, the total Power of the sound intensity is 10dB=10:1, However our ears are in one place and not everywhere within a sphere around the firearm. Likewise audio level meters cannot measure the power energy everywhere in a sphere around the gun's muzzle, but rather just a point in space ... at the microphone's face. Audio meters read SPL not total energy.
Sound Pressure Level (Pressure Wave) is a square function of a logarithm, so 6dB=2X, 10dB-3X, 12dB= 4X, 20dB-10:1 and 30dB=~30:1.
Many people confuse Pressure (SPL) and Power which is NOT a square function. So 3dB =2:1, 6dB=4:1,10dB=10:1, 20dB=100:1, etc.
Now, distance is a square function, so doubling the distance from the mic to the gun would equal a reduction of 4:1.
On your calculator::
to calculate Pressure Wave Intensity, enter the ratio, push 'Log' then times 2 for the dB reading.
to calculate Power (energy) enter the ratio, push 'log' and DO NOT multiply for the reading.
IMPORTANT: Sound level meters DO NOT read Power, only Pressure (SPL).
3dB on your meter is NOT double or half, but 6dB is.
These are not uncommon misconceptions. I have been in the acoustical engineering business for 55-years and, believe me, it's not uncommon to see them confused.
So if a suppressor takes you from 150dB down to 130dB (=20db reduction), that would be a 10:1 ratio of perceived loudness.
One more note; our hearing is also logarithmic in sensitivity. If it weren't we'd be able to hear a whisper as loud and normal speech as deafening.
I hope this clears up some of the confusion when selecting a suppressor.

I have a Yankee Hill Machine 9mm Sidewinder for my XDM Elite Tactical OSP. Very happy with it. Except for the cost. And then the tax stamp on top of that.

I'll be honest. I stopped reading after the first sentence, "Possibly the most maligned object in popular culture is the firearm silencer."
Suppressors may be maligned by some, but the most maligned object in popular culture? If had the time I could make a list (bump stocks, Glock clones, AR-15 rifles...) of things more maligned.
As someone with hearing loss and tinnitus, shooting with suppressors is a real pleasure and should not be as expensive as it is (or taxed, which is ridiculous).

Right? Honestly, how much can it cost to mold the cannister and baffles with connection threads/hardware?
Mr. Untactical

Pretty sure I'm not conceal carrying this, even without the suppressorWhy have one? Makes no sense. If there is a risk of getting in trouble why would anyone buy one?
And as with suppressors, added weight and can't conceal carry your pistol.
But it is a dream to shoot!

Ordinarily I am an optimist. But in this case, I can see it already. Should sales of silencers spike, some bureaucrat is going to take notice and say "My God! Silencer sales are on the rise! We'd better do something, and fast! (Drafts legislation to outlaw threaded barrels)"
