摘要

针对汽车噪声品质主观评价所需周期长、可重复性差且仅能比较出具有较明显差别的噪声样本等问题

在研究声品质客观量化的基础上

提出了一种以心理声学客观参数来描述噪声主观评价结果的计算方法.以6辆同类轿车匀速行驶时的车内噪声样本为评价对象

采用成对比较法进行声品质主观评价

计算各噪声样本的主要心理声学客观参数

通过多元线性回归分析

建立了声品质偏好性主观评价客观量化的数学模型.模型结果表明

相对于噪声分析中常用的A计权声压级和线性声压级

心理声学客观参数更适合于描述车内的噪声品质

其中响度和尖锐度是匀速行驶工况下车内声品质的主要影响因素.

Abstract

A modeling method by describing sound subjective evaluation with objective psycho-acoustical parameters is proposed to treat with sound subjective evaluation with long period

poor repeatability and quite differently comparable sound samples. The interior noises from six cars at constant driving speed are selected as the evaluation objects. The subjective evaluation test is carried out with the paired comparison

and several primary objective psycho-acoustical parameters of these samples are calculated. Following the multi-dimensional regression analysis

a sound quality subjective evaluation model is developed. The model with psycho-acoustical parameters gets more suitable to describe car interior noise quality than A weighted sound pressure level(SPL)and linear SPL. Loudness and sharpness incarnate the main factors of interior noise quality at constant driving speed.
