Question for those with a bit more suppressor knowledge than myself. Does increased suppressor backpressure typically equate to slightly higher decibel levels at the shooter's ear? In other words, if comparing two 5.56mm suppressors of roughly the same length and diameter, but one exhibits more backpressure on the rifle than the other, will the "gassier" suppressor lead to slightly higher decibel levels from the shooter's perspective?

With that in mind, since direct impingement guns vent excess gas at the ejection port and piston guns typically vent excess gas at the gas block, could one reasonably expect slightly better at ear performance from a piston gun over DI? Conversely, I suspect DI would have better numbers at the muzzle. Think suppressor optimized piston gun like the 416A5 versus an optimized suppressor ready DI gun like the SR16.

I ask these questions with the understanding the a lot of variables like ammunition and rifle type come into play here. Thanks in advance gents.
