In reference to phonation larynx fixation: computer graphic record.
The vocal apparatus serves phonation. It represents a biocybernetic self-regulating system, disposing of a feedback network of the central nervous system. The larynx is a self-induced vibrating system. The larynx, functioning as the phonation apparatus of the vocal apparatus, is a source of human voice. In every individual its frequency range corresponds to about eight semitones in speech and a...
متن کاملEffects of lung volume on vertical larynx position during phonation.
The vertical position of the larynx seems to be relevant to voice function. As a high vertical larynx position is often seen in hyperfunctional and strained voices, a lowering of a habitually elevated larynx is sometimes a specific goal in clinical voice therapy and different larynx-lowering exercises are used to achieve this goal. Earlier investigations have shown that pitch and to some extent...
متن کامل3D Computer Graphic Compression
Nowadays, 3D graphical models have become commonplace in most computer graphics related industries. The accuracy and realism of these 3D graphics are achieved by fine geometric details which present challenges in rendering performance; transmission bandwidth; and storage capacities. All these motivate a need for compressing geometric data. In this paper, I talk about two compression techniques ...
متن کاملAnalysis of flow-structure interaction in the larynx during phonation using an immersed-boundary method.
A recently developed immersed-boundary method is used to model the flow-structure interaction associated with the human phonation. The glottal airflow is modeled as a two-dimensional incompressible flow driven by a constant subglottal pressure, and the vocal folds are modeled as a pair of three-layered, two-dimensional, viscoelastic structures. Both the fluid dynamics and viscoelasticity are so...
متن کاملNeuromuscular induced phonation in a human ex vivo perfused larynx preparation.
Considering differences in laryngeal anatomy, degree of control, and range of voice qualities between animals and humans, investigations of the neuromuscular process of voice control are better conducted using a living human larynx in which parametric stimulation of individual laryngeal muscles is possible. Due to difficulties in access and monitoring of laryngeal muscle activities, such invest...
