According to this big barrel test:
The Palmers dual-vented brass seems to be the quietest of them all.

or you can make one the whole length of a ported barrel and extend it past the barrel.... you can look up the plans on the internet...I will not go into the layers of fiberglass and drilling holes into the inner tube or so on...but then ATF, FBI and locals will be looking for you....
I've never had a problem...but I play with some law enforcement types and the look and frown.....just beware....

Interestingly enough, the quietest gun I own, my Nova, has an unported barrel. Amcfall was telling me he adapted a heavily ported Dye barrel to one of his novas, and it was so quiet you could hear the insides doing their thing.

Is there a non moving nova barrel?

In my expeience, a low pressure gun with a standard heavily ported barrel (like the AA) is the quietest option. For instance, shoebox shockers always seemed very quiet to me.
This is a completely anecdotal story, but one setup that made a huge impression on me at the time (this was some years ago), was a minimag with a SP Venturi barrel. my friends and I were in complete awe as this guy would unload his paint at us and his marker appeared completely silent. All we heard was the whoosh of balls over our heads. This could have been a relative impression since everyone else were using unported Tippmanns at the time. Our theory is that the Venturi barrel directs sound back toward the shooter, so his targets hear less report. If you have never looked a a SP Venturi, the rearmost porting is angled back toward the rear of the marker. It is kind of a unique feature in a barrel, I don't think there are any others like it.
On the other hand, one of my buddies had a Trracer with a "raincover". It made very littel difference so he stopped using it.

King of the OFG
Hammerhead barrels all have "backward" angled porting, and the hype is that they are supposed to shoot most of the sound backward so as to sound less loud from the front.
Not sure physics supports that one myself, but it's a theory.
Porting does make a barrel quieter. It turns the "CRACK" into a bit more of a "POP". I like unported barrels myself simply for the intimidation factor.

Years ago, I replaced my non-ported 454 with a reverse ported version. The idea was that it would reduce recoil by diverting some gas backwards. The 50BMG Barrets use the same system.
Yes it did lower recoil, but made it MUCH LOUDER for the shooter. I would guess it would make is less loud the other direction? (I never tested that one... ahem).
On the other hand, look at loudeners. That divert sound away from the shooter, to the other direction. I did test that one, when Carter fired his Vector from behind me once. Made my ears ring.
So there is some science to it... I guess. Not exactly my field though.
