Acoustic absorption behind screenwall
So im in the process of building a new theatre room witg a 150" spandex cinemascope screen. The screen wall is 800mm off the end wall and the room dimensions are 5.2m x 8m.
I am looking for a solution to treat the wall behind the screen for sound absoption.
The goto diy material in the theater build forum is linacoustic. 2 layers with plastic in the middle for max low frequency absoption.
I cant get my hands on linacoustic in oz and have struggled to even find a duct insulation alternative. So Im thinking of using some rockwool bats or blanket and covering it with black carpet. Can anyone comment on the use of carpet for sound absorption, taking into account it is coupled with 50mm rockwool bats and will be 70mm off the wall.
