案例名称: 上海罗氏制药风机盘管噪声治理
类别: 工业厂房噪声治理
(1)设计方案/RoSE FCU noise control solutions
1.1隔音毡附着在设备外壳上吸收振动能量;
1.1 paste 2 mm noise carpets on the device to absorb vibration energy;
1.2 在FCU设备内壁增加9mm厚吸声材料,减少噪声反射叠加。
1.2 Around the Shell of FCU and in the inner wall of FCU to increase the 9mm thick sound-absorbing material to reduce noise reflection superimposed.
