摘要

The sound quality of the appliance has become a significant component in the purchaser's overall subjective evaluation. The sound of the appliance used to be evaluated by the noise level measured in dB (A). However, In some cases, the noise level measured in dB (A) can't match the feeling of people. So it is necessary to understand psychoacoustic in order to make noise quality evaluations that match the subjective experience of the purchaser. This paper presents an subjective evaluation technique which uses pair comparison statistical evaluation methods to evaluate the noise character of room air-conditioners and describes an objective evaluation system developed based on Zwicker's theory, which give quantitative objective evaluate parameters, such as loudness, sharpness, roughness etc. At the end of this paper, an example of application of the technique to improve the noise character of room air-conditioner is offered. After improvement, the total loudness was reduced from 5.995 to 5.135 sone and the sharpness was reduced from 1.629 to 1.165 acum.
