Sound Power Spectrum Guideline for a Refrigerator based on Subjective Evaluation

소비자 감성 평가를 통한 냉장고 Sound Power Spectrum Guideline

A weighted sound pressure level has been used to evaluate sounds test or sound quality test for a refrigerator up to present but the customer had different satisfactions of refrigerator sounds with different listening position. It means that there was a sound directivity caused by a position of fan or compressor. In this paper, we proposed a sound power spectrum guideline that represents total sound of refrigerator.
