摘要

针对某客车变速器异响噪声的非稳态特性，在ANSI_S3.4 2005标准基础上建立了Moore瞬时响度模型，并引入目前主流声学软件采用的Zwicker响度模型进行对比验证，最后将瞬时响度模型应用于车内噪声信号的识别及其定量评价。结果表明：Moore响度模型计算精度及其瞬时特征响度谱能量分布的清晰度均比Zwicker模型的结果更高，采用Moore瞬时响度有助于非稳态过程中的噪声源识别及噪声机理分析，用Moore响度来定量评价噪声具有可行性。

Abstract

To analysis the abnormal noise with unsteady characteristics in bus transmission, the Moore instantaneous loudness model was established based on ANSI_S3.4 2005, and cited the Zwicker loudness model for validation contrast, then the instantaneous loudness model was applied to the noise identification and its quantitative evaluation. The results show that the calculation accuracy and instantaneous specific loudness of Moore’s model are better than Zwicker’s, the Moore instantaneous loudness model is helpful to noise source identification and mechanism analysis in unsteady noise, and it’s feasible to use Moore loudness in noise quantitative evaluation.
