Origin of fan noise

noise can be contribution of several sources. For instance, Aerodynamic noise can be the result of turbulence caused by the blades of a rotating fan. Frequency and magnitude of noise gerenration is directly proportional to speed of ventilation fan.

Practical methods of controlling fan noise
Aircoustics suggest following simple methods of
reducing noise from fans:
1. Using damping—layer damping and constrained
layer damping;
2. Modification of supports to avoid obstacles before and after the fan
3. Lining ductworks with foam or fiberglass;
4. Changing fan speed controllers to reduce speed for
axial or centrifugal flow fans;

    Thanks a lot man! 🙂
