I don't understand this. They say a vacuum is somewhere around 89 decibels, and a vacuum is WAY louder than any sound coming from shooting suppressed subsonic 22's from my experience.

I'm listening to my wife wash dishes in the sink from 20 feet, and it sounds way louder than me popping off a suppressed subsonic .22 LR from a rifle. I hate to argue with smart people and data gleaned from expensive machines, but I'll trust my ears to tell me when a subsonic suppressed rimfire is too loud to shoot without earpro.

I don’t know what to say, man. The testing results show what the sound impulse measures. Last time I checked, the best .22 LR suppressors were around 118 decibels. The fact that you don’t register it as loud may say something about your hearing? I don’t mean that as anything negative towards you. Or maybe it’s just how we register the sound?
I know that when I got my first .22 suppressor, which was the quietest one on the market at the time (per TBAC Suppressor Summit data), I didn’t believe it made much difference at all from behind the rifle. I was shocked at how loud the suppressed shots were (but not when compared with unsuppressed - the difference was obvious there). I can hear the firing pin drop, but I also hear the sound of the shot. I still can’t tell the difference between subs and SuperSonics if I am shooting the rifle. But if I stand about 15 feet away from the shooter, I can tell the difference.
This can't be possible. Occasionally, a CCI Standard Velocity will break the speed of sound when i'm shooting suppressed, and the sonic boom when you're not expecting it is a deafening sound from a rimfire.

I agree. Subs are not in same stratosphere as supers sound wise.

The supersonic crack is around 125 decibels. Yes, the supersonics sound louder than the subsonic rounds. I am not saying there is no difference. I am just saying that I don’t usually register the difference when I am behind the rifle. As soon as I am observing someone else, the difference becomes apparent.

Was this on a semiauto? On a bolt action 22, it's a night and day difference for me.

No. CZ 457 with 16” barrel.
I mean no disrespect, because you seem like a very bright guy, but are you certain you've been using subsonic 22 LR ammo? I honestly feel like Helen Keller could register a difference between subs and supers from a CZ 457 with a can. Sonic booms, no matter how small, do not go unnoticed unless you're using incredible hearing protection.

Yeah. It’s silly quiet. All you really hear is the firing pin.

This isn't scientific, but I was curious. I just ran 4 shots out of a t1x with a B&T tiger ti. Phone with a downloaded db meter, phone facing up on deck railing, infront of the can, within 10".
970 fps ammo, out of 16" barrel.
The cycling on the bolt registered almost as loud as the shot.
Says a max 95 db. The sharp spikes are the shots.
Oh, and @ 50 seconds I burped into the mic out of curiosity, and maybe to piss the wife off.
