Abstract:
In this paper the author has analyzed the relation between human subjective sense and various environmental noise level indexes and conducted a comprehensive study of the correlation between different sound levels and subjective annoying rates using the principle of applied mathematics and experimental psychology. Comprehensive indexes in sound environmental assessment, SNL and CNL, are introduced and the method of limited isolated sound level indexes has been changed into the calculation of psychological effect of sound over humans as assessment volume in environmental noise assessment so that the assessment index can reflect directly psychologically acceptable limits of humans to surrounding sound. This shows the percentage of people affected by noise under the surrounding sound. Meanwhile, the author also gives a detailed description of the application of the assessment index to the analysis and prediction of sound environmental quality, of construction project planning, and of the advantages of the assessment index.
