家用电冰箱非稳定运行噪声评价方法标准解读

Interpretation for Evaluation Method of Unsteady Running Noise for Household Refrigerators

依据常规测试方法可以检测冰箱在平稳运行状态下的噪音水平,同时可对冰箱噪音进行谱分析并得到其关键频率,但冰箱在实际运行过程中的噪音是变化的。本文将建立冰箱非稳定运行嗓声的测试方法,能够有效的对冰箱运行的实际嗓音水平进行评价并提出指导意义。

The noise levels of refrigerator can be detected in the smooth running through regular testing method and the spectrum of refrigerator noise can be analyzed with its key frequency obtained.But the noise of the refrigerator in operation is changing.This paper establishes the testing method of the unsteady noise in refrigerator,which can effectively evaluate the actual noise level of refrigerator operation and provide guiding significance.
