摘要: The crack noises propagating from a refrigerator disturb residents in household; however, the reasons behind mechanisms of such have not been identified yet. In this study, modern household refrigerators are and their root causes explored. appropriate parameters for overall Fourier analyses first determined noise characteristics typical under various conditions presented. Then, special test rig providing remote control subcomponents including compressor, fan heater is designed structural acceleration sound pressure measurements inside outside quiet room performed. acoustic vibration conducted by separately controlling each subcomponent. explored using results analyses. Some solutions to minimize also summarized.
