| 摘 要： | 为了降低家用制氧机的运行噪声,采用了近场声全息技术进行制氧机噪声场数据采集和声场重建.根据声压频谱图、声压辐射云纹图、声速频谱图、空间声速分布图以及时间/频率/声压图谱等可视化信息,选择了针对声源、传播途径的隔声罩、涂敷阻尼胶、石膏板吸声和加装部件减振胶垫等简单有效的噪声控制措施.试验表明,近场声全息技术是一种有效地进行噪声源控制和声辐射特性研究的重要工具.

| Abstract: | In order to reduce operating noise from home oxygen generator,noise field data acquisition and sound field reconstruction of oxygen generator had been completed by using near field acoustic holography technology.According to visual information,such as sound pressure frequency spectrum,sound pressure radiation cloud maps,sound frequency spectrum,space velocity distribution maps,and time/frequency/sound pressure map,simple and effective noise control measures were selected for the sound source,acoustic transm... |
