Acoustic impedance of 180mm long pipes: simulations and measurements

Augustin Ernoult, Romain Viala, Jérémy Cabaret, Juliette Chabassier et autres

The data correspond to the input acoustic impedance of 180mm long pipes. These impedances are either measured or simulated by one of the authors. The associated Gitlab project provides scripts which can be used to process these data. Configurations studied The configurations …

How localized nonlinear losses condition the acoustical design of a self-sustained oscillator: the clarinet and its register hole

Nathan Szwarcberg, Tom Colinot, Christophe Vergez, Michaël Jousserand

The register tube marks the invention of the clarinet in the early eighteenth century, tripling the range of its ancestor, the chalumeau, and giving it the widest range among wind instruments. Opening this narrow tube causes the fundamental frequency of the played …

Assessing the consistency of numerical models for wind instrument impedance

Augustin Ernoult, Jérémy Cabaret, Juliette Chabassier, Tom Colinot et autres

Numerical simulation of the input impedance of wind instruments is the basis of much work in music acoustics.However, the accuracy and reproducibility of such simulations across different contributors remain little documented.This study aims to benchmark the reliability of numerical simulations for pipe …

Influence of the basins of attraction in the register jumps of the clarinet

Nathan Szwarcberg, Tom Colinot, Christophe Vergez, Michaël Jousserand

When playing the clarinet, opening the register hole allows for a transition from the first to the second register, producing a twelfth interval.On an artificial mouth, the blowing pressure range where the second register remains stable can be determined by gradually varying …

Real-time demonstrators to exhibit, investigate and teach transient behaviors in nonlinear dynamics, focused on musical instruments

Tom Colinot

Nonlinear dynamical systems exhibit various transient behaviors, whose understanding is required to fully apprehend how the system responds to sollicitations.This work focuses on multistable systems, where several stable solutions coexist for a given value of the system's parameters.In these settings, transients condition …

Dynamical Behavior of a Brass Instrument Around a Double Hopf Bifurcation

Martin Pégeot, Tom Colinot, Jean-Baptiste Doc, Vincent Fréour et autres

Self-sustained musical instruments, such as wind or bowed string instruments, are capable of producing sustained sounds from a continuous supply of energy.These instruments exhibit transient regimes when the sound appears and during note changes.In this study, we focus on certain transient behaviors …

Evaluating the Reproducibility of Impedance Measurements of Wind Instruments

Jean-Pierre Dalmont, Augustin Ernoult, Jérémy Cabaret, Henri Boutin et autres

Input impedance is a physical quantity that allows the objective characterization of wind instruments.It is now a common measurement in research labs and wind instrument factories.To be relevant, these measurements must achieve a precision higher than what a musician can detect.Although the …
