Popis:	Localized nonlinear losses are taken into account in a simple Raman clarinet model.The complete system is expressed as an iterated map, enabling to study the stability of the different playing regimes. A parametric study is carried out with respect to three major parameters: blowing pressure, embouchure and nonlinear losses coefficient.The model exhibits the well-known effect of reducing the extinction threshold when nonlinear losses increase.However, the stability analysis also shows that increasing nonlinear losses increases the oscillation threshold.
