摘要豪华声是高档轿车最重要的声品质之一。以前的工作表明，由于许多不同的内部声音的影响，很难通过仅使用A加权声压级来客观地评估豪华声音。系统地研究了这类声的特性，提出了一种新的客观评价豪华车声品质的指标。这是通过基于路径分析的七个主要车内音质指标的系统组合而开发的。这些轿车内的声音是由一个豪华汽车俱乐部的成员评估的。然后，通过使用声音度量（心理声学参数）和多元回归，七个主要的室内声品质指标。采用多元回归分析建立客观评价与主观评价之间的相关性模型。新开发的豪华音质指数可应用于基于客户偏好的试验车阶段的七款高级乘用汽车的客观评价。
Abstract Luxury sound is one of the most important sound qualities in a premium passenger car. Previous work has shown that, because of the effects of many different interior sounds, it is difficult to evaluate the luxury sound objectively by using only the A-weighted sound pressure level. The characteristics of such sound were systematically investigated and a new objective evaluation was proposed of the luxury sound quality index. This was developed by the systematic combination of the seven major interior sound quality indices based on path analysis. These sounds inside a passenger car were evaluated by the members of a luxury automotive club. Then, by using sound metrics (psychoacoustic parameters) and multiple regression, seven major interior sound quality indexes were developed. Multiple regression was used to model the correlation between objective and subjective evaluation. The newly developed luxury sound quality index can be applied to the objective evaluation of the seven premium passenger cars in a pilot car stage based on the customer preference.
