The cooling tower sound insulation barrier can also be called: cooling tower sound insulation screen, cooling tower sound absorption plate, cooling tower sound absorption screen, cooling tower sound insulation barrier, etc. The mixed type sound absorption screen is adopted, the top is the sound absorption unit, and the following parts are the sound insulation units. After reasonably determining the length and height of the sound barrier, a noise reduction of 10-25dB (A) can be obtained. The cooling tower noise barrier has good noise reduction effect, with sound insulation of 10-25dB (A). High structural safety, strong resistance to natural forces and man-made destruction. It has the advantages of low investment, fast construction speed and obvious landscape effect. The cooling tower sound barrier is combined and assembled, and can be assembled freely between modules, which is durable and convenient for installation and maintenance. The cooling tower noise barrier is increasingly recognized by some residential areas and office buildings, which can greatly reduce some noise in our lives. The noise barrier of the cooling tower is a hybrid sound barrier. The top part is a sound absorption unit, and the lower part is a sound insulation unit. After reasonably determining the length and height of the sound barrier, a noise reduction of 10-25dB (A) can be obtained. Cooling tower sound barrier components include columns, unit plates, other connectors, etc. Cooling tower sound barrier materials include aluminum plate, plastic spray plate, PC plate, etc. It should be noted that because the cooling tower itself is high, the sound barrier is high, taking into account the project investment, wind resistance, earthquake resistance and other factors.
