As　we　know,　noise　emitted　from　air　fan　in　a　freezing　compartment　of　a　refrigerator　is　a　main　source　except　refrigeration　compressor＇s　noise.　The　freezing　air　coming　from　the　fan　directly　impinges　upon　baffle　plate　mounted　in　front　of　the　fan　and　results　in　a　strong　flexural　vibration　of　the　wind　baffle　plate　embedded　in　a　freezing　compartment,　which　further　leads　to　structural　vibration　of　the　inner　walls　of　the　freezing　compartment,　thus　a　large　amount　of　noise　in　which　low-frequency　noise　components　dominate　radiates　to　the　outside.　Because　of　large　size　of　the　baffle　plate＇s　surface,　fan　noise　is　significantly　amplified　due　to　the　presence　of　the　baffle　plate.　In　order　to　reduce　the　noise　radiated　by　air　cooling　refrigerator,　a　new　method　by　locally　applying　the　impervious　thin　layer　damping　structure　to　the　solid　baffle　plate　installed　in　the　freezing　compartment　is　presented　in　this　paper.　The　hard　baffle　plate＇s　partial　region　just　in　front　of　the　freezing　air　fan　is　replaced　by　the　impervious　thin　layer　damping　structure　through　opening　a　circular　hole　on　the　baffle　plate.　Although　the　air　impinging　on　the　thin　layer　damping　structure　will　increase　much　more　noise,　but　the　generated　noise　is　chiefly　a　mid/high-frequency　noise,　which　can　be　easily　insulated　by　closing　a　door　of　the　freezing　compartment　during　fan＇s　operating　period.　Furthermore,　while　the　door　opens,　the　freezing　air　fan　will　stop　immediately,　noise　arising　from　the　membrane　flexural　vibration　won＇t　generate　any　more.　By　this　noise　reduction　method,　total　sound　power　level　of　the　test　refrigerator　is　reduced　by　2.4-2.6　dBA　in　different　operation　conditions.
