Autor: Takuto Honda, Mayuka Kanaya, Isao T. Tokuda, Anne Bouvet, Annemie Van Hirtum, Xavier Pelorson

Publikováno v: The Journal of the Acoustical Society of America. 151(5)

To examine the quasi-steady approximation of the glottal flow, widely used in the modeling of vocal fold oscillations, intraglottal pressure distributions were measured in a scaled-up static vocal fold model under time-varying flow conditions. The le

Multimodal radiation impedance of a waveguide with arbitrary cross-sectional shape terminated in an infinite baffle

Journal of the Acoustical Society of America, Acoustical Society of America, 2019, 145 (4), pp.2561-2564. ⟨10.1121/1.5099262⟩

Simulations of waveguide acoustics require a description of the boundary condition at the open end. For problems involving higher order transverse modes, it is often described by a multimodal radiation impedance matrix. Expressions for the computatio

Controlling chaotic oscillations in a symmetric two-mass model of the vocal folds

Autor: Oriol Guasch, Annemie Van Hirtum, A. Inés Fernández, Marc Arnela

Publikováno v: Chaos, Solitons & Fractals. 159:112188

Human phonation is a highly non-linear process in which subglottal flow emanating from the lungs induces self-oscillations of the vocal folds. In normal conditions, this results in the generation of a regularly pulsating volume velocity that becomes

International audience; The vocal fold vibration, and hence acoustic source properties of voiced speech sounds, rely on the vocal folds elasticity which is therefore a crucial part of the underlying fluid-structure interaction for healthy as well as
