Brass musical instruments

During a two-month research internship, I worked on a physical model of brass musical instrument (Figure). I developed a time-domain numerical tool for the simulation of nonlinear sound waves, which combines variable cross-section, viscothermal losses and a model for the musician’s lips. Numerical examples show that the nonlinearity of wave propagation in the bore has a major influence on the properties of the numerical instrument, see the 2017 Acta Acust. united Ac. publication.
