摘要
针对滚筒洗衣机整机噪声的特点及在其传播途径分析研究的基础上，运用频谱分析法诊断ＸＱＧ５０－１８Ａ前置式滚筒洗衣机的噪声源。按照测试结果，采用自由层阻尼处理，取得了降噪３．５ｄＢ（Ａ）的效果。
In view of the general features of the noise and its transmission channels of the rolling washing machine,this paper discusses how to diagnose and analyze the source of the noise by means of frequency spectrum analysis.The free-layer damping treatment has been applied,and the results show that the noise can be reduced by about 3.5dB(A).
