loudness evaluation 中文意思是什麼
-
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。 -
After exhaust pipe and fan system are modified, the total loudness is reduced from 11. 5 to 9. 6 sone, the fluctuation strength and sharpness are reduced. at the end of this paper, a standard of subjective and objected evaluation method of room air - conditioner is also offered
此外，在文章結尾，作者在對現有空調器進行大量噪聲測試和總結的基礎上，首次提出了《房間空氣調節器聲質量主、客觀評價規范》 ，並在生產中進行實際應用。
