Acoustic rhinometry predicts tolerance of nasal continuous positive airway pressure: A pilot study

American Journal of Rhinology, Volume 20, Number 2, March-April 2006 , pp. 133-137(5) Authors: Morris, Luc G.; Setlur, Jennifer; Burschtin, Omar E.; Steward, David L.; Jacobs, Joseph B.; Lee, Kelvin C. Abstract: Background: Nasal continuous positive airway pressure (nCPAP) is usually the first-line intervention for obstructive sleep apnea, but up to 50% of patients are…

Physiological change in nasal patency in response to changes in posture, temperature, and humidity measured by acoustic rhinometry.

American journal of rhinology 2006;20(5):456-62. Authors, Lal Devyani; Gorges Melissa L; Ungkhara Girapong; Reidy Patrick M; Corey Jacquelynne P Abstract: BACKGROUND: Acoustic rhinometry has been used to assess nasal patency and to calculate nasal cavity volume. This study used acoustic rhinometry to assess changes in nasal patency after alterations in posture, unilateral mechanical obstruction, temperature,…

Volumetric Measurements of Vocal Tracts for Male speakers from Different Races

Clinical Linguistics and Phonetics, 2006 Authors: S. A. Xue, G. J. Hao, and R. Mayo Conclusion: “Research examining physiologic and acoustic characteristics of culturally diverse populations is sorely needed, but rarely reported. The major aim of this study was to quantify vocal tract dimensional parameters (oral length, oral volume, pharyngeal length, pharyngeal volume, total vocal…

Normative Standards for Vocal Tract Dimensions by Race as Measured by Acoustic Pharyngometry

Journal of Voice, 2006 Authors: S. A. Xue and J. G. Hao Conclusion: “Acoustic pharyngometry evaluates the geometry of the vocal tract with acoustic reflections and provides information about vocal tract cross-sectional area and volume from lip to the glottis. Variations in vocal tract diameters are needed for speech scientists to validate various acoustic models…
