Noise is one of the most important quality indicators for a refrigerator, which will seriously affect user’s experience and is one of the hot spots of con-sumer complaints. In this paper, we develop a refrigerator noise evaluation method more effective than A-weighted sound pressure level. Its results are more closely related to the subjective feelings of users. Through the subjec-tive evaluation of the noise quality of different types of refrigerators, we found that, compared with A-weighted sound pressure level, annoyance and loudness of the refrigerator noise are more related with each other. On this basis, we conducted a noise loudness subjective evaluation experiment to de-termine the function relationship between refrigerator noise annoyance and loudness and to measure the noise loudness threshold user can accept of dif-ferent types of refrigerators. The evaluation result according the method is better consistent with users’ subjective feeling and the after-sales of the en-terprise. The research results of this paper may provide reference for the de-velopment of new standard for refrigerator noise evaluation. |
