A large machine sitting on the floor in a workshop emits noise with the following power 1W/125HZ, 1.5W/250HZ, 2W/500HZ, 2.5W/1000HZ, and 2W/2000HZ. The dimension of the workshop is 20mX15m with 6m ceiling. The walls, ceiling and floor have average absorption of 0.05, 0.6 and 0.02, respectively. If the machine is located at 5m from one end of the workshop, and an office wall needs to be built at 5m from the other end, calculate: The SWL in each frequency band, a) Room constants R for the workshop and office.
