I am building acoustic panels for my home theater and thought it would be interesting to use a fabric I liked on one side of the front wall panel and Blackout Cloth on the other side of the panel. When I am listening to music, which is most of the time, the decorative fabric side would be showing. When I wanted to watch a movie I could flip it around and the screen/Blackout Cloth would be showing.

My question is about the effect of the Blackout Cloth on the efficacy of the panel. I don’t know to what extent it would be reflective versus absorptive. The Blackout cloth is a poly-cotton blend infused with layers of rubber. I am hopeful that at worst it would be the same as having no acoustic panel and just the same as a screen on the bare wall. At best I would have a fully functional acoustic panel.

Please advise.

P, Do not use this methodology. It will not permit enough air flow.

First I’ll assume your using Studio Pro acoustic foam . Use at least two to four inches of foam . The more foam the better. The more you use the higher the absorption at lower frequencies. An air gap between the foam and wall will also improve performance. Next, if you cover the front use acoustic fabric from Guilford of Maine. In regard to the rear, do not cover it with anything. You do not want to limit airflow. You could cover the rear with an acoustic fabric but it would not serve as a projector screen. Basically, don’t cover the rear of the foam .
