In this paper we present a simple physical model of the trombone
reproducing the generation of brassy sounds for loud tones. Two
implementations are considered for the nonlinear wave propagation
effects: one in which these effects only affect the radiation of sound,
the other in which they also take part in the oscillation process.
We explain the different hypothesis which lead to these different models
and compare the numerical results they give.
