| Abstract: | In this paper, it mainly analyses the noise of the industrial square in the colliery, direct against the characteristic of a lot of noise sources, sound level high, prominent low frequency and farther propagation distance to noise, chooses rational scheme to control separately, after noise synthesis, the aim is that the A sound level for the noise of industrial square in the colliery square follows to bring down to 50 decibels, and the working condition of workers and living environment of residents around are improved. |
