Study on Noise Prediction and Reduction in Coupled Workshops Using SEA Method
Figure 10
The plasterboard after noise control with a different area of leakage (Case 1: no leakage and the padding plasterboard connects with the existing one very well; Case 2: the area of the leakage occupies 0.1% of the total area of the plasterboards; Case 3: the area of the leakage occupies 1% of the total area of the plasterboards).
