Improved Multi-Level Fuzzy Recognition for the Evaluation of the Acoustic Environment

Abstract:

Since the method of single factor and multi-object for acoustic environment evaluation would get inaccurate results, an improved multi-grade fuzzy recognition model is proposed. Taking into account the factors of affected time and the number of people affected, it is a multi-factor and multi-object evaluation method. This method not only eliminates the wrong results caused by the misuse of the maximum subordination principle, but also avoids weakness of the principle. Moreover, it is applied to evaluate acoustic environment of Hohai University Xikang Road campus. The evaluation results correspond with the subjective attitude of the teachers and students, which proves the validity and correct.
