I currently have alot of sound retention in my living room where I watch films,tv and gaming. I've been looking into acoustic panels and found they can be a fairly big cost. The room walls are wood studed with insulation and 18mm plasterboard then skimmed and painted,I then have an engineered oak floor which i dont really want a rug on. (I've read else where that that can stop some echo in the room)
What i'm thinking of doing if it works and is the right way to go about it,is to put building insulation inside these canvases
which is opposite this
Would this be a good idea or really just a waste of time, all other walls are bare so would I need some more panels else where?
