Operating characteristics of refrigerator changes according to conditions and repeats with specific cycle. and radiated noise fluctuates with operating characteristics. In this study, Record 14 refrigerators considering housing environment and classify into 4 types based on components. and Analyze the changes of noise pattern and characteristic of sound quality index for each type. Finally, This study is expected to be used as a useful source in psycho-acoustics study of refrigerators noise.
