This paper presents a semi-empirical formula for predicting the noise spectra of axial flow fans in a free field. The basic assumption made in deriving this formula is that sound radiation from an axial flow fan in a free field is primarily due to the fluctuating pressure exerted on the fan blade su

## Abstract A new method for the determination of a distributed FET noise model is presented. It is based on the extraction of the intrinsic noise‐correlation matrix of an elemental section of the device from the device's noise figure, measured for only one source‐impedance state at a number of fre

The possibility of using a two-port model to analyze the source character of an in-duct axial fan is investigated. It is found that in the plane wave region the tested fan closely resembles an ideal dipole located at the fan blades. This finding is in agreement with earlier investigations which have
