Would it help at all to stuff some sound deadening foam or fabric in the open area of the shroud, especially with a big vented air stripper?
I know the expansion area in front of the muzzle makes most of the difference, but im making an air stripper that will be dumping the initial blast backwards into the shroud and making chambers in the rear section of the shroud for the air to foil through.
Would putting felt or something in those chambers reduce the DBs any more than just venting the air into those chambers?
