基于DOE的家用净水机声场噪声优化探究

Abstract

Abstract: This paper describes the noise distribution condition of one reverse osmosis water purifier sold on the market based on CAE analogue simulation, noise spectrum test and vibration test. This aim is to investigate the noise diffusion of the water purifier by attaching the two-component sound-absorbing cotton on different panel. Then analyze the consequence which is caused by the attaching position by the design of experiment (DOE) analysis methods in order to attain the best attaching position. What could be shown in the result is that the two-component sound-absorbing cotton have an excellent sound-absorbing property for the noise between medium-high frequency, the best combination scheme have a 4dB(A) noise reduction which caused an obvious sound quality improvement.

Key words: Water purifier, Two-component cotton, DOE, Noise control
