消声器动态评价实验室



本实验室依据GB/T25516-2010(ISO 7235:2003,IDT)建设,用于测量通风类消声器、弯头、T型连接管和风道末端等设备的插入损失、全压损失和气流噪声。

消声器动态评价实验室分为地下风机和和地上测试管道及接收室组成,地下风机前后设置有消声器,以降低风机运行时产生的设备噪声。

 

    The laboratory was built according to GB/T25516-2010(ISO 7235:2003,IDT), aiming at measuring the insertion loss, total pressure loss and airflow noise of ventilation muffler, elbow, T-connection tube and equipments at the terminal end of air duct.

    The muffler dynamic evaluation laboratory is composed of the underground fan, the aboveground test pipe and the sound reception room. The muffler is provided before and after the underground fan to reduce its noise while running.
