Answer ONLY items 5-8. Room dimensions are: LxWxH = 8.50 m, 5.0 m, 3m. Originally, the room had linoleum flooring with an absorption coefficient of 0.03. Two opposite walls were cladded with unglazed bricks with an absorption coefficient of 0.02, the one having the entrance gypsum door (2.1 m X 0.80 m) with 0.05 abs.co.; the other two were just bare concrete with sliding glass window openings of 1.80m x 1.20 m each; the bare concrete with an abs.co. Of 0.31 and the window glass with 0.18, the ceiling, too , had bare concrete as its finish at 500 Hz. The client would like to renovate the space into an acoustical studio room and would like to change the ceiling and the flooring. The ceiling will have a vinyl faced fiberglass panel with an abs.co. of 0.71, and the floor will have mineral fiber tiles with an abs.co. Of 0.66, all at 500 Hz.
