Simulation of a player-clarinet system

A time-domain simulation model has been developed for investigating the player-clarinet system. The three components that constitute the simulation model consist of the player's air column, reed, and the clarinet. The player's air column is represented in terms of an analogous circuit model to obtain the mouth pressure. The reed is represented as a damped, driven, nonuniform bar. The clarinet is represented in terms of a scaled version of its input impedance impulse response. A convolution of the impulse response with the volume velocity determines the mouthpiece pressure. Use of the model is valid for both smalland large-amplitude reed oscillations. Many of the nonlinearities associated with the clarinet are incorporated in the model in a rather natural way. Several vocal tract configurations are investigated to determine the influence of the vocal tract on the player's air column impedance and the concomitant effect on the clarinet tone.
