自《工业企业噪声卫生标准》发布后,许多工厂正在积极开展噪声的治理工作。但由于经验不足,有的单位往往把“吸声材料”与“隔声材料”用反,结果适得其反。从现象上看吸声材料与隔声材料都是降噪材料,但两者在材质的要求上有着根本的不同。 众所周知,当声波传播时遇到某一障碍? Since the promulgation of the Noise Standard for Industrial Enterprises, many factories are actively carrying out noise management. However, due to lack of experience, some units tend to use “sound-absorbing materials” and “sound-insulating materials” in reverse, which is counterproductive. From the point of view of sound-absorbing materials and sound-absorbing materials are noise-reducing materials, but the two have a fundamental difference in material requirements. As we all know, when the sound waves encountered some obstacles?
