| Abstract: | Noise level as high as 113dB(A) generated by air current of axial flow fan at the outlet of ventilation shaft of a coal mine poses big environment problems. Characterized by low frequency, the noise is abated by using specially designed equipment. Calculation involved in the design is described with discussions. |
