Amplitude-dependent modal coefficients accounting for localized nonlinear losses in a time-domain integration of woodwind model
Nathan Szwarcberg, Tom Colinot, Christophe Vergez +1
This article develops the design of a sound synthesis model of a woodwind instrument by modal decomposition of the input impedance, taking into account viscothermal losses as well…
Diversity of ghost notes in tubas, euphoniums and saxhorns
Rémi Mattéoli, Joël Gilbert, Soizic Terrien +4
The ghost note is a natural note which can be played exclusively on bass brass instruments with a predominantly-expanding bore profile such as tubas, euphoniums or saxhorns. It sta…
Minimal blowing pressure allowing periodic oscillations in a model of bass brass instruments
Rémi Mattéoli, Joël Gilbert, Christophe Vergez +4
In this study, an acoustic resonator -- a bass brass instrument -- with multiple resonances coupled to an exciter -- the player's lips -- with one resonance is modelled by a multid…
Time-domain numerical modeling of brass instruments including nonlinear wave propagation, viscothermal losses, and lips vibration
Harold Berjamin, Bruno Lombard, Christophe Vergez +1
A time-domain numerical modeling of brass instruments is proposed. On one hand, outgoing and incoming waves in the resonator are described by the Menguy-Gilbert model, which incorp…

Regime change thresholds in flute-like instruments: influence of the mouth pressure dynamics
Soizic Terrien, Rémi Blandin, Christophe Vergez +1
Since they correspond to a jump from a given note to another one, the mouth pressure thresholds leading to regime changes are particularly important quantities in flute-like instru…
Is the jet-drive flute model able to produce modulated sounds like Flautas de Chinos ?
Soizic Terrien, Christophe Vergez, Patricio De La Cuadra +1
Flautas de chinos - prehispanic chilean flutes played during ritual celebrations in central Chile - are known to produce very particular beating sounds, the so-called sonido rajado…
Explicit Mapping of Acoustic Regimes For Wind Instruments
Samy Missoum, Christophe Vergez, Jean-Baptiste Doc
This paper proposes a methodology to map the various acoustic regimes of wind instruments. The maps can be generated in a multi-dimensional space consisting of design, control para…
Response of an artificially blown clarinet to different blowing pressure profiles
Baptiste Bergeot, André Almeida, Christophe Vergez +2
Using an artificial mouth with an accurate pressure control, the onset of the pressure oscillations inside the mouthpiece of a simplified clarinet is studied experimentally. Two ti…
