I am a neophyte on actual figures but i believe that are some figures on noise ratings between 1 & 2 piece barrels, but i go with feel or my own preception, myself. Again, i will stress what you hear while firing the gun yourself & the noise signature from 10 feet away will be different, possibly much less. So do some testing yourself on that.
But still, play with the oressure settings, see about the HF valve from ID and have fun with it.
