If you decrease the firing delay on a cannon to a really small number, it won't make a firing sound until you let go of the trigger/firing button.
It will only make one firing sound whenever you stop firing.
Other than that, you will probably just need to deal with the noise. It is rather annoying in certain situations.
Edit: I realize you were referring to wing guns, but you can't stop the sound on those.
Damn, alright I appreciate it anyway.
