摘要
本文在对驾驶室内声场特性进行分析的基础上,提出了驾驶室壁面进行吸声降噪处理后,耳旁噪声A声级降噪量的理论计算方法。通过TY354拖拉机试验验证,理论计算值与实测值吻合良好。
This article is on the basis of the analysis to the cab sound field characteristic, proposes the theoretical calculation method of the ear noise a acoustic level noise reduction amount after the cab wall surface carrying on sound absorption reduction processing. Through the TY354 tractor experiment confirmation, the theory predicted value and the actual value tally well.
