摘要

In this paper two major differences between clarinet-like instruments and oboe-like instruments have been studied: a conical shape and the presence of a pipe-neck downstream of the double reed. First of all, the well known effects of the conical bore have been investigated. Whereas the input impedance of a cylindrical bore shows resonance at all the odd multiples of the fundamental resonance frequency, the input impedance of a conical bore has its maxima at the even multiples of the fundamental (which means all the multiples of another fundamental frequency two times larger than for a cylindrical pipe). A method which simulates this behavior has been studied. It consists in simulating two cylindrical bores connected perpendicular to the reed. Numerical simulation have shown the consistency of the algorithm with the theory Concerning the effect of the pipeneck, a model has been proposed, leading to a nonlinear relation between air pressure close to the reed and air pressure at the begining of the bore (i.e. end of the pipeneck). This relation is parameterized by the discharge-losses-coefficient associated with the pipeneck. Three qualitatively different behaviors have been highlighted, two of them being hysteretic. Analytical conditions to obtain each of the three different behaviors are given in the present paper. Experiments are being carried out to check the validity of the model, and the magnitude order of Cd in oboe-like instruments. Indeed, nothing guarantees that type 2 and type 3 behaviors will be observed. However, preliminary stroboscopic visualisations of double-reed oscillations (made by R. Causse) confirm that the reed may jump during its cycle between two positions. The present model will be used in sound synthesis applications. Sound examples will be presented at the conference.

Causse制造）证实了簧片在其两个位置之间的循环中可能会跳跃。本模型将用于声音合成应用程序。声音示例将在会议上介绍。
