Saw during sawing noise pollution generated

In the construction and decoration industry widely used circular saw, because of its simple structure, wide application, easy maintenance, high production efficiency, can not currently be replaced by other cutting tools. However, this saw generated during  synthetic diamond  serious noise pollution, load noise, load noise, the noise spectrum showed a high   cutting tools and pulse characteristics, noise propagation distance, and very harsh, very irritable. Since cutting the complexity of noise generation mechanism, has long studied the rotating cutting noise mainly confined to the classification of the main sound source and transmission pathways analysis.
