A machine located in a building occupies an approximate rectangular volume 6m x 5m x 3m high. The space averaged sound pressure level at 1m from this rectangular surface is 83 dB and at 3m from the surface it is 81.2 dB in the 500 Hz octave band. Calculate the room constant in the 500 Hz octave band. R = Number m² [Your answer should be accurate to within 10% ] Calculate the sound power level of the machine in the 500 Hz octave band. Lw= 102 dBre10-12 W [Your answer should be within +/- 2 dB ]
