用等效车的方法将K Takagi等人提出的单车道单车种负指数的分布的车流噪声计算公式加以推广,使之可应用于对多车道多车种自由车流的累计分布噪声级Lx和等效声级LΦp作出预报多次应用的结果证实本计算公式的精度可满足实用要求。

本文提出“虚墙”法作为众所周知的虚声源法的对偶,并将它应用于车行隧道和城市街道混响声场的交通噪声计算。根据这个概念,由单车种等间距分布的车流所产牛的声场可等效于位于一对假想的刚硬墙壁之问的单一车辆所产牛的声场。这对虚墙与隧道或街道的边界形成一个围闭空同,使得经典室内声压级计算公式可以应用于计算交通噪声混响声压级。本文还给出两个应用实例与实测数据相比较。

【期刊论文】Membership functions for fuzzy set evaluation of concert hall acoustics
吴硕贤, Shuo-xian WU, E. Kittinger
J. Acoust. Soc. Am. 93 (1), January 1993,-0001,():

By summing up the opinions of many experts about concert hall acoustics, this paper suggests a more complete factor set and more detailed membership functions for the fuzzy set evaluation of concert hall acoustics. The mean forte sound-pressure level LpF representative of subjective loudness, is introduced in the factor set in addition to those already considered previously.

【期刊论文】A New Criterion for Concert Hall Loudness Evaluation
吴硕贤, Shuoxian Wu, Qingmei Li, Erwin Kittinger

Loudness is one of the most essential parameters for assessing the acoustical quality of an auditorium. But owing to the lack of an authentic criterion, it remains unresolved how to evaluate the loudness in concert halts. In this paper LpF, the mean forte sound pressure level of tutti-sound is suggested as a criterion to describe the loudness in a hall. The prediction procedure of the LpF value distribution in a hall is demonstrated, Comparison between predicted and measured LpF levels is given. Tentative optimum and allowable LpF values for concert halls are also doscissed.
