| Abstract: | An experimental investigation has been carried out to study the feature of the noise caused by cross-flow fans, especially the effects on noise power spectrum and sound level A by eccentricity of the vane wheel and the streamline form of blade. The results may provide technical basis for noise control of cross-flow fans. |
