How to eliminate noise in water pump room

Pump room noise is generally a low-frequency noise problem! At present, this situation exists in many supporting residential areas in China. In the current building structure, it generally exists in the following equipment, such as water pumps, transformers, elevators, heat pumps, central air conditioners and so on! However, many residential developers or property inaction, resulting in no complaints from owners!

The noise of water pump house is mainly composed of refrigeration unit, motor and fan, and its noise is mainly low frequency noise. Low-frequency noise is characterized by strong diffraction ability, strong propagation ability and difficult sound absorption, which is the most difficult problem to solve in noise control. The high acoustic energy density in the computer room increases the pollution degree of transmission noise. The key problem of noise control in pump room is pump noise, which is a kind of mechanical noise and fluid noise. Mainly spread through foundation. Soft connection and vibration reduction are the key points of control, and the design of vibration reduction system is the most important. The second key issue is indoor acoustic energy. Excessive sound energy will increase the transmitted sound energy, and structural sound absorption is an effective way to absorb sound in pump house.

At present, the main improvement method in China is to isolate the noise and vibration sources and transmission channels!
