柴油发电机组静音箱的设计

Design of sound attenuated enclosure of diesel generation sets

静音箱在噪声控制中有良好的降噪效果。根据噪声源的分布及控制特点,分别采用隔声、吸声和消声等噪声控制技术综合利用设计箱体结构。在箱体尺寸受限帛的条件下,利用有限的空间实现了较大的降噪量,取得了良好效果。

It is resultful to apply the sound attenuated enclosure to controlling undesirecd sound. According to the distribution of noise source and characteristics, noise isolation, noise absorpition and muffling are individually applied to each part in accordance with their feature. Under the limited size of the enclosure, the higher noise reduction is obtained in limited space, and good effectiveness is gained.
