产品简介
production introduction
消声室（半消声室）是用于机电设备、空气动力设备测试其声学性能的设施设备；可用于营造特别安静的区域及房间，也可以将高强度噪声设备置于消声室（半消声室）内，消除其噪声振动向外辐射（如各类发动机、冲床、锻造机械等），达到消除噪声危害的目的。
anechoic chamber is the facilities, which is used for test the acoustic performance of mechanical, electrical equipment and air power equipment; it can be used to create a special quiet area and room, it also can put the high intensity noise equipment in the in the anechoic chamber (semi anechoic chamber), to eliminate the noise vibration and radiated outward (such as all kinds of engine, punching machine, forging machines, etc.).
我公司生产的消声室技术性能                      
the performance of the anechoic chamber
半消声室本底噪声≤35db(a)；全消声室本底噪声25db(a)。
anechoic ground noise≤30db(a)
下限频率：31.5hz。
lower limit frequency: 31.5hz
室内具有良好的通风性能（机械通风）。 
good ventilation performance
全消声室可完全断开与外界的刚性接触（减振、隔振）。
it can be disconnect the rigid contact from outside
(vibration, vibration isolation)
   隔声量：半消声室40db(a)    全消声室50 db(a)
easy to install and remove
可装置各种照明设备。
it can be planted all kinds of lighting equipment
基本结构
basic structure
可生产制作为组合模块，在室外空地组合安装。
can be made into compound module and installed in the open air area.
可在混泥土及砖墙上安装。
can be installed on the concrete and brick.
如果是全消声室，须增设隔振（弹性）底座及减震器。在隔振底座上安装隔声和吸声模块。在隔（吸）声模块上安装钢龙骨、钢板网，便于人员行走及安装设备。
if it is full anechoic chamber, it should be added flexible base and shock absorber, also installed sound insulation and absorbing module on the base, next installing steel on the sound insulation and absorbing module, and steel net, it is easy for staff to walk and install.
