52 Citations | Grooved blade tips amplify the fan noise, so measures should be taken to control the noise. |
16 Jun 2014 | Thus, while the attenuation of fan tones remains paramount, the ability to simultaneously reduce broadband fan noise levels has become more desirable. |
18 May 2012 | Thus, while the attenuation of fan tones remains paramount, the ability to simultaneously reduce broadband fan noise levels has become more appealing. |

20 Citations | In this paper, an improved algorithm for active control of fan noise is proposed. |
39 Citations | The data presented indicates that this turbulence is the dominant source of noise above 1.5 kHz for the fan tested. |
Such correlations may contribute to redesign guidelines for simultaneous reduction of noise and improvement of efficiency at prescribed fan performance. | |
8 Citations | We demonstrate the important role of the area of the sound-absorbing liner between fan Rotor and Stator ensuring significant noise reduction. |
18 Citations | The results indicate the limits of maximum noise reduction which manufacturers may expect using existing fan designs and also indicates the methods for achieving maximum noise reduction for these configurations. |
27 Citations | Although the main contribution to fan noise generation is due to mechanical sources, the bands in which aerodynamic noise is generated by these fans correspond to frequencies especially unpleasant to the human earl Therefore, the research presented in this paper may be of considerable interest, establishing a starting point for the design of quieter and more efficient fans. |
