摘　　要：本文概述了衡量洗碗机噪音的声学参数、六点法测试方式以及根据该测试方法对一种减振降噪方式的验证。根据本文提出的洗碗机的减振降噪方式,通过LMS噪音测试设备对改善前后样机的时间历程曲线、频谱图进行对比分析,结果表明,采用该种减振降噪方式不仅能够降低整机的噪声值,而且能够明显降低电源倍频程处的峰值。This paper outlines the acoustic parameters for measuring dishwasher noise,the six-point test method,and the verification of the vibration reduction according to the test method.A Vibration and noise reduction method of the dishwasher is proposed,and LMS noise testing equipment is used to compare and analyze the time history curve,spectrogram and 1/3 octave of the prototype before and after the improvement.The result indicates that this method can not only reduce the noise value of the whole machine,but also significantly reduce the peak value of the power supply octave.
