I am interested in knowing where the blast sound emanates from on a suppressed firearm. For example, I believe on average a decent 9mm suppressor will still have about 125db coming from it. Does anyone know what percentage of this noise comes straight out of the muzzle as opposed to resonating from the suppressor walls? Has anyone ever measured the amount of noise that radiates from the body of the suppressor itself (excluding what comes out of the muzzle end)?
