隔声罩的结构形式及隔声效果研究

Study on Structural Form and Soundproof Effect of Acoustic Enclosure

介绍了隔声罩的结构类型及隔声罩的设计计算以及隔声罩的应用实例,结果表明:隔声罩的隔声能力取决于其形状和尺寸、结构刚性、罩上开口、缝隙面积、平均吸声系数、隔声材料的隔声量和耗损因数等多种因素。

The structural forms,designing calculation and application examples of the acoustic enclosure were introduced in this paper.The results showed that the soundproof effect of acoustic enclosure was influenced by some factors,including its shape,size,structure rigidity,hole area,average sound absorbing coefficient,and sound transmission and wear index of acoustic materials and so on.
