%X Dimensionless representation of the pressure signal measured inside a flue organ pipe shows that the dimensionless amplitude is a function of the Strouhal number only. This behavior indicates that amplitude saturation is due to a non-linear interaction of the acoustic flow with the jet flow. Correlation of these results with flow visualizations stresses the importance of vortex shedding at the edge of the labium. (...) The aim of the present paper is to demonstrate the power of dimensionless representation of experimental data as a tool to track down basic physical mechanisms in the sound production of wind instruments. Using the example of the amplitude of the fundamental oscillation mode we will, by correlation with flow visualizations, obtain a caricature which may explain some features of the sound production in flue instruments.
