From what I know, inside most theaters, there are rugs, curtains, acoustic panels, and of course seats. Curtains can be made of velour, velvet, velveteen and whatnot. Or synthetic imitation. Do all of these fabrics have similar acoustic properties? What are the most common fabrics found in public movie theaters?\n\nSo, I have two acoustic panels here, one 100% polyester, the other is something more textured, it is advertised as being "Pro acoustic fabric" with no other information given. I have no idea what it is. These two acoustic panels do not seem to impact sound the same. I do prefer the acoustic panel with more texture to it. I would be thankful if someone knowledgeable can provide maximum information about this matter and also acoustic properties of commonly used fabrics and their graphics. Thanks.
