In this paper, the author established the model of objective evaluate parameters of sound quality and develope d an objective evaluation system which could give quantitative objective evaluate parameters, such as loudness, sharpness, roughness, psychoacoustics annoyance ( pa ) etc. paper also describes an subjective evaluation investigation ir " " hich 16 subjects used pair comparison statistical evaluation methods to evaluate the noise character of room air - conditioners, the results show that there is generality good agreement between quantitative objective evaluate sound quality parameters and subjective evaluation. at the same time an example of application of the technique to improve the noise character of room air - conditioner is offered
此外本文還介紹了一個應用聲質量評價技術改進kfr - 50hw / e2d空調器聲質量的實例，通過對空調器室外機管系、導流罩、出風網等進行改進，空調器的聲質量得到了明顯改善：在室外風量提高164m ~ 3 / h情況下，聲音響度下降16 ，波動強度明顯改善，尖銳度指標也略有下降，作者同時總結了不同改進措施對產品聲質量影響的方式，以期為今後的聲質量改進提供借鑒。In the future, we should step forward to study how to minish the voltage spike, to improve the assistant switch network, to study another new structure topology, for enhancing the capability of the maglev chopper
