摘    要:建立Zwicker瞬时响度、Moore瞬时响度、Moore时变响度计算方法,引入ArtemiS软件的Zwicker时变响度计算方法,并采用4种模型针对汽车发动机怠速噪声、汽车关门声和电机驱动汽车加速噪声3种典型的稳态、冲击与阶次扫频的信号进行响度计算,对比分析4种模型用于时变噪声响度计算的适用性.研究表明:噪声频率成分与幅值变化越剧烈,Zwicker与Moore时变响度计算偏差越大,瞬时响度模型的计算越精确;Moore时变响度时频分析有助于噪声来源和发生机理的分析与识别.

关 键 词:响度计算模型  时变噪声  适用性分析

Abstract:Three sound loudness calculation models,including Zwicker instantaneous loudness model,Moore instantaneous loudness model and Moore time-varying loudness model,and the cited Zwicker time-varying loudness model in ArtemiS,were applied to calculate the time-varying loudness of three typical noises such as steady engine idle noise,impulsive door closing noise and order-swept electric vehicle pass-by noise.Based on the loudness amplitude and time-frequency loudness results,the applicability of the four loudness...
Keywords:loudness calculation model  time-varying noise  applicability analysis
