Studio building in progres…. I am a little insecure about silencing outside noise through air inlet. First this: Is a splitter silencer the same as a plenum silencer? Everest talks about plenum silencer, everyone here talks about splitter silencers…..
Second: For a fresh air inlet (that is a hole through the outer wall without a fan, outlet has a fan) would it be a good idea to build a two layer gypsum box lined with rockwool?
Any help will be apprecited.
I didn’t find the right solution from the Internet.
