    Numerical investigation of acoustic characteristics of 3D human vocal tract model with nasal cavities

  • Original language description

    Acoustic resonance characteristics of 3D human vocal tract model without and with nasal andnparanasal cavities were computed. Nasal cavities (NC) form the side branches of the human vocal tract and exhibit antiresonance and resonance properties which influence the produced voice quality. Developed FE models of acoustic spaces of nasal and vocal tract for vowel /a:/ are used to study the influence of (NC) on phonation. Acoustics frequency-modal characteristics are studied by modal analysis and numerical simulation of acoustic signals in time domain is performed by transient analysis of the FE models.
