The Optimal Choice of the Long-term Measuring Spots for Regional Environment Noise

On the basis of the measuring results of gridding method for regional environment noise,a optimal and comprehensive assessment index is chosen by eigen-analysis method.The affiliation value of each noise measuring spot is calculated.At the same time,the measuring spots are classified according to the values and several typical monitoring spots for long-term noise measuring are chosen.It provides a new way for choosing regional long-term noise measuring spots.
