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.
