This paper presents a simple turbulence noise model that could be used for time domain
simulations of flue instruments. The turbulence noise sources are deduced from spectra measured
inside a small recorder-like flue organ pipe and by using a one-dimensional representation of the
instrument. The amplitude of these sources display a maximum located at a Strouhal number
corresponding, for Reynolds numbers > 3000, to the maximum instability of a plane jet. The
turbulence noise source appears to have a dipolar character and its amplitude scales with the
square of the jet velocity.
