  1. 4178. Design and Validation of a Cyber-Physical Laryngeal Model of Vocal Fold Posturing (FA2026/793)

    Vocal fold (VF) posturing influences the fluid-structure–acoustic interactions that govern human phonation. However, the influence of VF posturing on phonotraumatic vocal hyperfunction is still unclear. This deficiency arises, in part, because current experimental modeling approaches rely on simplified VF and laryngeal geometries with limited degrees of freedom. Consequently, current...

    Voice disorders affect millions of people across Europe, with significant implications for quality of life. Understanding the physical mechanisms underlying phonation and their variation under disturbances remains a central challenge. While the fundamental principles of voice production are well established, accurately modelling the complex fluid–structure–acoustic interactions between the...

  3. 4180. Aeroacoustic Simulation of Soft Phonation Employing a Kinematic Model of Mucosal Waves (FA2026/789)

    A12 Numerical, Computational, and Theoretical Acoustics

    This work presents a hybrid computational framework for the three-dimensional simulation of human phonation, combining prescribed vocal fold motion, computational fluid dynamics, and aeroacoustic wave propagation. The adopted kinematic mucosal wave model is derived from laboratory experiments of soft phonation, and its kinematics are imposed as dynamic boundary conditions in the incompressible...

    A12 Numerical, Computational, and Theoretical Acoustics

    A recently started research project brings together experienced research teams from Czechia, Germany and Austria to expand the knowledge on the nature of the mucosal wave which is important for (1) improving the accuracy of the mathematical and physical models of voice production, and for (2) more insightful diagnosis of voice disorders. Based on experimental observations, kinematic laws will...

  5. 4182. Impact of Dental Morphology on the Aeroacoustic Production of the Fricative [s]: A Numerical Study Comparing Neanderthal and Modern Human Dentition (FA2026/605)

    A12 Numerical, Computational, and Theoretical Acoustics

    The sibilant fricative [s] is produced by a turbulent jet passing through a constriction formed by the tongue and the hard palate. Upon impinging on the upper incisors, this jet induces an acoustic dipole at the tooth edge, which constitutes the primary source of the frication noise characteristic of [s] (Stevens, 1971).In this study, we investigate the physical and aeroacoustic principles...
