The main noise sources of cooling tower are exhaust fan noise, mechanical noise and water pouring noise generated by driving mechanism. Fan noise is a kind of aerodynamic noise, including turbulence noise and rotating noise. When the air flows through the blade surface, it will be detached at the back of the blade, and a series of vortices will be formed in the tail due to the viscosity of the air flow, resulting in turbulent noise, which has continuous spectrum characteristics. The rotating noise is produced by the pressure pulsation when the blade is rotating. Its frequency spectrum is narrow-band, low intermediate frequency and has obvious peak value. The noise of the fan is mainly transmitted to the outside through the vent at the top of the cooling tower.
