摘要
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,并通过TY354拖拉机进行了试验验证,结果表明;理论计算值与实测值吻合良好。
Based on analysing characteristics of noise field in cab, a theoretical calculating method of noise [dB(A)] reduction value at tractor operator's ear after acoustic absorption treating on cab wall are presented. A verifing test with TY354 tractor has been made. Theoretical calculating value coincide with measured one.
