The results from an intensive research program show that it is possible to reduce the sound power level of cooling fans by 15 dB(A) by altering blade cord width and swept leading and trailing edge lines. Combination with the reduction of the pressure drop can result in a step of 20 dB(A) and a reduction with 25 percent of the absorbed power. Testing was conducted in accordance with recognized international measuring standards and the results will be presented, including consequences for cooling tower and condenser design.
