摘要
声音品质研究已经成为汽车噪声控制新的发展方向,心理声学为主观评价的实现提供了理论依据。介绍目前国内外在汽车噪声主观评价中常用的参数,包括应用较多的心理声学参数,如响度、尖锐度、调制度和有调度,以及其他三个常用参数和两个综合评价指标,并给出各个参数较准确的定义和解释。
Sound quality has becomes a new developing research area of noise control of vehicle, and psychoacoustics provides a theoretical basis for the realization of the subjective evaluation. This paper summarizes the parameters of subjective evaluation currently used in automobile noise, including psychoacoustic parameters, such as loudness, sharpness, modulation and tonality which are employed mostly. Other three commonly used parameters and two comprehensive evaluation indexes are also introduced briefly, and a more precise definition and explanation corresponding to each of them are given.
