空调压缩机噪声声品质主客观评价及其相关性研究

通过对某生产厂家的空调压缩机进行现场噪声测试,采用评分法对噪声声品质偏好性指标进行主观评价,并计算出A声级、响度和尖锐度值作为声品质的客观评价指标.对主客观评价结果进行相关性分析及线性回归分析,提出了声品质主观偏好性值的预估模型.研究结果表明,压缩机噪声声品质主要受A声级、响度和尖锐度的共同影响.

Subjective and Objective Evaluation of Compressor Sound Quality and Correlation Research

The compressor for air-conditioner was tested in noise at site. Subjective evaluation of the sound quality preference was carried out with rank marking. A-weighted sound level ,loudness and sharpness were calculated out as objective evaluation labels of the sound quality. The correlation analysis and linear regression analysis were carried out between the subjective and objectlve results. The prediction model was proposed for subjective preference. The research results indicate that the compressor sound quality is mainly affected by A-weighted sound level ,loudness and sharpness.
