Acoustics 2015 Hunter Valley 15-18 November 2015Abstract: This study focuses on the understanding and modelling of noise radiated from a mine ventilation fan, with the ultimate aim of designing quiet fan impellers. Experimental measurement are presented that suggest the main noise sources on mine ventilation fans are related to the impeller and consist of tonal components created by the passage of the blades past the volute tongue and broadband noise associated with turbulent flow interacting with the blades.
