RT= 1.3s

Conclusion:The reverberation time for the workshop is 1.3s . It is a good and recommended range of sound level. The sound is within the space and does not take much time to reflect. Comfortable environment is produced for the user in the area as there are fewer echoes produced.

4.0 EXTERNAL NOISE SOUND PRESSURE LEVEL (SPL)

Total intensities = (1.995 x 10-4) + (1 x 10-4) = 2.995 x 10-4

Combined SPL = 10 log l1

5.0 Sound Reduction Index 5.1 Zone: Workshop

The table shows the sound pressure levels of common sound sources

From the table above, the average sound pressure produced by the workshop is around 85dB. The west side of the café , consists of the curtain windows (45dB) with the area of 18m² and the east side consists of the brick wall (48dB) with the area of 17m².
