Question

the volume of a room is 200m³. the surface area of the wall is 220 m², the floor area is 120 m². thr average absorption coefficient are 0.03 for walls, 0.80 for ceiling and 0.06 for floor. find the average absorption coefficient and reverberation time.
​

Answer 1

Answer:

. The wall area of the room is 220m3

, The floor area is 120 m2

and the

ceiling area is 120m2

. The average absorption coefficient (1) for walls is 0.03 (ii) for the ceiling is 0.80 (iii)

for the floor is 0.06. Calculate the average sound absorption coefficient and the reverberation time. (110.40
