摘　　要：随着空调噪声的持续降低,声品质问题成为空调新的重要研究方向。通过多重比较研究,建立了基于参考评分法的声品质主观评价方法,评价结果的时效性和准确度更高;通过对A声级、响度、尖锐度、粗糙度、语言清晰度和突出比等声品质客观评价参数敏感度分析,基于多元线性回归分析方法,建立了声品质客观评价模型;声品质客观评价模型与声品质主观评价结果的符合性超过90%。With the continuous reduction of air conditioning noise,sound quality issues have become a new important research direction for air conditioners.Through multiple comparative studies,Establishes a subjective sound quality evaluation method based on the reference scoring method,and the timeliness and accuracy of the evaluation results are higher.Through the sensitivity analysis of objective evaluation parameters of sound quality such as A-weighted sound level,loudness,sharpness,roughness,speech intelligibility,and prominence ratio,based on the multiple linear regression analysis method,an objective evaluation model of sound quality is established.The conformity between the objective evaluation model of sound quality and the subjective evaluation results of sound quality exceeds 90%.
