Noise control and optimal control brings blindness

As for the major noise source generates acoustic field distribution mechanism and little research, and therefore can only measure sawing noise analysis rather than quantitative estimates. This gives noise control and optimization of control brings blindness.  synthetic diamond powder  the main sound source, aerodynamic noise, resonance noise, mechanical noise that extensive research and analysis, mechanical  Abrasive grinding wheel noise dominates. In many of the mechanical noise, impulsive noise is a top priority, because in the sawing process, due to periodic sawtooth interaction with the workpiece to be cut, the equivalent of the blade and the workpiece are subject to a periodic pulse.
