车内噪声质量的主观评价及其改善措施的研究与发展

汽车产品的声质量评价问题已经成为汽车制造商和研究者关注的焦点之一。综述了国际上对车内噪声质量的主观评价及其改善措施的研究进展,重点介绍了AVL公司开发声质量评价软件和HONDA公司确定以心理声学客观参数表述的汽车运动感和豪华感公式等工作,也介绍了其他一些公司致力于实现声质量标准客观参量化的研究。论及了某些汽车厂商在产品设计和开发过程中采取的声质量改善措施,特别阐述了能够实现选择性降噪的噪声主动控制系统在此方面的显著作用和巨大潜力。对该领域研究的发展趋势进行了预测。

Study and Development of Subjective Evaluation of Inner Noise Quality and Improvement

Acoustic quality evaluation for automotives becomes one of focus for automotive manufacturers and automotive studies.Study and development of subjective evaluation of automotive inner noise quality and improvement in the world are summarized.The acoustic quality evaluation software developed by AVL and the automotive sport feeling and luxury feeling equation expressed with the psychological acoustical objective parameters that developed by HONDA are introduced,and studies by other companies on objective parameterization of acoustics quality standard are introduced.Improvement of acoustic quality during product design and development by some automotive makers are introduced,and the remarkable function and great potential of the active noise control system,which can do selective noise reduction,is especially introduced. The development trend of the field is predicted.
