But starting 10' away, you can barely hear the lower frequency noise because it does not travel as far and looses energy REALLY fast.

this is a big thing too ... the pitch of the sound... it's also REALLY hard to judge the noise level of an aeg when your shooting and the thing is right up against your ear...
I've been right beside or shooting 2 or 3 aegs ... and they all sound very close to the same noise levels...
however 30-40ft out... they were VERY different ... the bone stock clone gun still sounded like a sewing machine you could hear the wind up and move/run/duck ... the mildly tuned guns (proper shimming, adjusted, etc) .. were alot harder to pick up and you only really heard the piston hit and the barrel pop and by then it was pretty much too late to react... the fully tuned and tweaked gun (helical gears, pads, good motor etc) with a foam filled silencer .. you barely got a pop.
now .. these are all outdoors guns, all running 380-406 fps ... so none of these guns engage under 60ft ... we all carry pistols .. so typically none of us engage under 100ft ... so same "test" @ 100ft
-the stocker @ 390fps ... still hear the windup, still hear the smacky poppy (this is actually still easy to hear 150ish ft out too ..)
-the mildly tuned/tweaked @ 380 fps ... barely hear the pop, not enough to react really, but enough to know where it came from (again harder to hear 150ish ft out.. but still able to get an idea where the shooting is coming from)
- the full on build @ 406fps ... you hear nothing, just bb's either hitting or going past... no real way to identify location other then if you see the bb's in flight. ... it's also good to note too the other 2 were firing single rounds, the full tuned model ended up with a nice feature on a full auto on off full pull a perfect double tap... so it was firing twice every time during this "test"
now.. this test wasn't scientific, it wasn't perfect... it was 3 completely different guns ... stocker was a kraken, mild tune was a metal bodied M4, and the full tune was an AUG ... that nice quiet Aug ... if you were the one firing it.. with the gearbox basically against your cheek.. you'd swear the whole forest and people the next town over could hear you.
