Being in NYC, I don't get to mess with guns much. When I was younger living at home, my dad had a pretty decent collection of rifles. We went out shooting targets on occasion, was a good time. <br /> <br /> Always been curious about "silencers" and how they actually work. I assume that's what these suppressors are. This is pretty cool.<br /> <br /> The website might be kinda "spammy" depending on what kind of browser you have so I'll post a second link below that goes directly to the Youtube video.

They're not "silencers" except in the minds of those who want all guns gone anyway.<br /> <br /> Think of them as industrial-strength mufflers - still well over 100db for any real round, but worlds better than the 150+ of some things without!

If I believed what I see on TV, they would reduce the noise down to the level of a pea shooter.

The *only* things that are that quiet are bolt-action 22LR with subsonic ammunition.<br /> <br /> Distance and knockdown of a flea at that point, and the package is ...large.

So is there such a thing as a silencer that can really quiet a large round?

They make it so shooting will not harm your hearing. Still loud and unmistakably a gun shot.<br /> <br /> In order to get any large caliper pistol or rifle movie quiet, it would be too large to handle. Think putting a car muffler on a handgun.

"Really quiet" is relative.<br /> <br /> My Gemtech HVT takes what would be a permanent hearing damage shot down to about unsuppressed .380 - loud, to be sure, but many orders of magnitude smaller.<br /> <br /> It's also 9" long and 28 ounces - in addition to the gun.<br /> <br />

I knew that such a device can't bring the sound down to a quiet little "thup" as portrayed in movies/TV. In the video, the gunshots with the suppressors that don't fail seem to have a different tone, more mechanical sounding and less like the report of a rifle. It's impossible to tell how loud it actually is. Gotta dig the super slo-mo anyway.

Obviously if I was gonna have a gun, I want the one whit the hit man/spy style silencer so you can execute people in a crowd and nobody realizes it. Just like the movies.

You'll be waiting an eternity for that, get a knife!<br /> <br /> The thing that suppressors change to a degree is the report, as you note above - it's harder to determine shot location because one of the audible queues is changed substantially.<br /> <br /> That said, if someone is shooting from far away enough that that effect works...you're not going to "see" them anyway!

My understanding is that unless the round is subsonic you still get a pronounced crack similar to a sonic boom only bullet sized rather than jet sized.

You do, but it's nowhere near as pronounced, or easily source-identifiable.

I watched the "extended" youtube video of that demo. They point out that the supressor is normally not made of clear acrylic so it contains and therefore hides most of the gas and resulting flame. For military use at night that may be at least as valuable as the noise reduction.

Anyone heard a subsonic 300 Whisper/Blackout round through a can? Most are shooting high-velocity Blackout rounds but the original Whisper idea was a quiet yet still relatively powerful round, at least compared to the 22. I have always wondered how well they succeeded in that?

As others have noted, even a suppressed round is pretty loud. What I found interesting was the the sonic crack of the bullet going overhead breaking the sound barrier, the first time I worked the pits at Camp Perry.

I found an answer to my own question, and it appears that if one wants something harder hitting than a .22, and still very quiet, a 220 grain 30 caliber Whisper/Blackout round kept around 1000fps seems to be the ticket. But the round still makes a loud noise when it hits. <br /> <br />

Needs to have comparison versus unsuppressed, and from different positions - the operator position outdoors is the quietest for any can (since it's all going out even further away from the user), and without compared to the normal unsuppressed round, hard to say how good it is.<br /> <br /> Regular supersonic 7.62N is "hearing safe" with a can outdoors, after all.
