Blade Dampers - Noise Generated

Sound power level generated in blade dampers

Sponsored Links

The noise - sound power level - generated in single opposed blade dampers can be estimated from the chart below:

blade dampers noise generation diagram

  • 1 mm water H2O = 9.81 Pa = 9.81 N/m2 = 1 kg/m2 = 0.0736 mm mercury = 0.9677 10-4 atm = 0.00142 psi = 0.0394  in H2O

The noise level generated depends on the volume flow through the damper and can be corrected using the table below

Volume Flow
(m3/h)
Noise Correction
(dB)
100 -10
200 -7
500 -3
1000 0
2000 3
4000 6
8000 9
16000 17
