Pretty much correct, assuming a few things.
Basically from my experience the get-it-quiet list is:
- Gear whine - Whine from a poorly-shimmed gun seems to be the biggest "win" you can have right away so everyone's first priority when quieting their gun down is the mechbox. Shim your gears and adjust your motor height and grease well.
- Piston slap - This is the sound of your piston hitting the cylinder head. You can reduce this by using 40 duro sorbothane pads ( http://clandestineairsoft.com/index....products_id=42 ), which will also adjust your angle of engagement (you'll need to possibly remove teeth on your piston to accomodate this).
- Compression pop leaving the barrel. Silencers work here, though in my experience you need a lot of length and foam, so don't just get one of those tiny ones. If you want to impress your airsoft buddies with a "silenced" noise, remove all the foam (keep it in a clean baggie somewhere). If you have something like an aluminum G&P silencer, your gun will now make a *foomp!* bottle-esque noise and people will come up to you at games remarking on how "silent" your gun is. I have no idea why this seems to trick people's brains as well as it does.
- The motor itself doesn't make a ton of noise, which you can verify by running the motor outside of the gun, but I'm guessing that all other things being equal, high torque neo motors will sound better due to lower rpms and increased efficiency.
Two experiments you can run to teach yourself how much noise a gun makes and where:
- Take your motor out of the grip and place it on the table, still connected. Make sure to hold it down steady with one finger on the can because it's about to try to fly off the table. Also watch for flinging grease. Pull the trigger. That's the noise your motor makes. This is unavoidable, but a very minor component of the system.
- Take your entire gun to the nearest couch or bed and completely cover and smother it in as many layers of sheets, pillows, bed covers, jackets, throws and snuggies you can find. Now make sure that the very end of the barrel is able to stick out of the pile somewhere so that it is exposed to the room. Press down on the pile HARD with one arm and put the other arm inside of the pile and find the trigger. Pull the trigger a few times. That's the sound of compression pop along with whatever other sound was transmitted down the barrel. If you do this experiment correctly, you won't hear much gear/motor noise. This experiment will help you evaluate a given suppressor system. Having a laptop and a copy of Audacity (audio program) and setting up your experiment identically each time apart from the suppressor itself helps isolate and measure the effect of the variable you're changing.
I should also add that in my experience it seems that the sound that travels the furthest in outdoor games seems to be compression pop.
