1. Calculate the volume of each room below, and use the table on page 165 to estimate a good reverberation time for the purpose stated. a. L = 40 m, W = 20 m, H = 10 m. To be used for chamber music. b. L = 12 m, W = 14 m, H = 4 m. To be used as a lecture hall. 2. A room has dimensions L = 13 m, W = 17 m, and H = 5 m. Give the area of each wall, the ceiling, and the floor. (you should have a total of six areas!)
