(9 points) To keep with their "industrial" style, the walls, floor, and ceiling are all made of concrete (a = 0.02 Sab/ft2). Prior to any treatment, what is the reverberation time of the room with no occupants? (7 points) You recommend covering both of the short walls with curtains (a = 0.12 Sab/ft2), both long walls with plasterboard (a = 0.15 Sab/ft2), and covering the floor in carpet (a = 0.20 Sab/ft2). With the new treatment, what is the reverberation time now in the space? Does it fall within the acceptable limits above?
