050 - Evaluation of loudness and sharpness of refrigerator noise
Jeon J., You J., Lee J., Joo J.
Abstract
Sound quality characteristics of refrigerator noise were investigated and subjective evaluations for the noise were conducted. A two-category and nine-point scale was used for the evaluation. Refrigerator noise was presented to subjects using a stereo dipole system in an anechoic chamber. Correlation analysis results between sound quality parameters and subjective evaluation result showed that Zwicker's loudness was a major factor for annoyance of refrigerator noise. The just noticeable difference (jnd) for loudness was around 0.5 sone. Zwicker's sharpness of refrigerator noise was also investigated.
