METHOD FOR EVALUATING A SOUND QUALITY INDEX OF A REFRIGERATOR NOISE BASED ON A REAL HOUSING ENVIRONMENT

摘要

PURPOSE: A method for evaluating a sound quality index of a refrigerator noise is provided to perform an exact sound evaluation based on similar noise level which general users feel in a real housing environment.;CONSTITUTION: A refrigerator noise in a dead room is measured using a plurality of noise level measuring units which are installed around the refrigerator. The noise level is compensated into a noise in a real housing environment. The noise compensation includes a background noise compensation, a directivity compensation, an attenuation/reflection compensation, and a vibration transmission compensation.;COPYRIGHT KIPO 2011
