  General measures for noise control of cooling towers:vMACooling tower noise reduction treatment manufacturer

  When the closed cooling tower is running, the sound of the fan and the water flow will produce certain noise, which will affect the health and daily life of the operators and residents. Victims and the scope of injury are broad and fluid, and measures to protect victims are not feasible. Only measures to control the source of noise and cut off the route of transmission can be taken. The principle of the sound insulation screen is to use the isolated noise source to make the sensitive building in the sound shadow area to achieve the purpose of reducing the sound level.vMACooling tower noise reduction treatment manufacturer
