Curtain fabric is acoustically absorptive, and can be added to a room for a very cost effective method of controlling the reverberation of sound. They are often called Variable Acoustic Curtains, because of their ability to be easily adjusted, depending on how much absorption is required. For example, a stage with a full orchestra may require different curtain configurations than when there is a solo violinist on stage. There are many designs for variable acoustic curtains, the most common is to have them mounted onto a track, moving horizontally for adjustment. All curtain fabric must be flame resistant to meet building code. Please contact a representative to help customize your order, receive additional specifications and color cards.
