Changes in the Human Vocal Tract Due to Aging and the Acoustic Correlates of Speech Production

Journal of Speech, Language, and Hearing Research, 2003 Authors: S. A. Xue and G. J. Hao Conclusion: “This investigation used a derivation of acoustic reflection (AR) technology to make cross-sectional measurements of changes due to aging in the oral and pharyngeal lumina of male and female speakers. The purpose of the study was to establish…

An Interpretation Method for Objective Assessment of Nasal Congestion with Acoustic Rhinometry

Laryngoscope, 2002 Authors: B. Mamikoglu, S. M. Houser, and J. P. Corey Conclusion: “Separate computed tomography (CT) and magnetic resonance imaging (MRI) correlation studies have confirmed the reliability of AR measurements.” “Objective nasal assessment with AR allows us to assess whether an obstruction is structural, mucosal, or mixed with an objective grading of the disease…

Acoustic Reflection: Review and Clinical Applications for sleep-Disordered Breathing

Sleep and Breathing, 2002 Authors: J. S. Viviano, D.D.S. Conclusion: “The potential clinical usefulness of AR in the treatment of patients with SDB involves all stages of treatment: initial screening of patients, establishing patient candidacy, evaluating nasal patency, determining mandibular posture that optimizes airway patency, determining orthotic titration settings, and verifying continued efficacy of orthotic…

Acoustic Reflection: Review and Clinical Applications for sleep-Disordered Breathing

Sleep and Breathing, 2002 Authors: J. S. Viviano, D.D.S. Conclusion: “The potential clinical usefulness of AR in the treatment of patients with SDB involves all stages of treatment: initial screening of patients, establishing patient candidacy, evaluating nasal patency, determining mandibular posture that optimizes airway patency, determining orthotic titration settings, and verifying continued efficacy of orthotic…

Utility of Noninvasive Pharyngometry in Epidemiologic Studies of childhood Sleep- disordered Breathing

American Journal of Respiratory and Critical Care Medicine, 2002 Authors: K. J. Monahan, E. K. Larkin, C. L. Rosen, G. Graham, and S. Redline Conclusion: “The usefulness of any diagnostic test depends on numerous factors, including its feasibility, predictive ability (regarding predicting clinical endpoints or discriminating subgroups of the population), precision (or reliability), accuracy, and…

Detection of Positional Airway Obstruction in Neonates by Acoustic Reflection

American Jornal of Respiratory and Critical Care Medicine, 2000 Authors: P. Jarreau, B. Louis, L. Desfrere, P. W. Blanchard, D. Isabey, A. Harf, and G. Moriette Conclusion: “In conclusion, this study showed that the [Acoustic Reflection] method is an effective way to diagnose abutment of an ETT against the tracheal wall in infants. The method…

Effect of Nasal Surgery on the Nasal Cavity as Determined by Acoustic Rhinometry

Otolaryngology–Head and Neck Surgery, 1999 Authors: B. Kemker, X. Liu, A. Gungor, R. Moinuddin, and J.P. Corey Conclusion: “Acoustic Rhinometry (AR) was used to objectively measure the success of septoplasty in relieving nasal obstruction caused by septal deviation.” “AR measurements were successful in detecting increases in CSAs 1, 2, and 3 [Cross Sectional Areas] but…

Anatomic Correlates of Acoustic Rhinometry as Measured by Rigid Nasal Endoscopy

Otolaryngology–Head and Neck Surgery, 1999 Authors: J. P. Corey, V. P. Nalbone, B. A. Ng Conclusion: “Acoustic Rhinometry (AR) evaluates the cross-sectional areas and volume of the nasal cavity through acoustic reflections. Successive valleys displayed on an AR graph are believed to correspond to anatomic landmarks. To assess the anatomic accuracy of AR, we performed…

Detection of the Nasal Cycle with Acoustic Rhinometry: Techniques and Applications

Otolaryngology–Head and Neck Surgery, 1999 Authors: A. Gungor, R. Moinuddin, R. H. Nelson, and J. P. Corey Conclusion: “Acoustic rhinometry is an appropriate method for detecting and recording the nasal cycle in normal subjects in terms of the cross- sectional areas and volume of the nasal cavity.” “When AR is used to evaluate volume changes…

Objective, Noninvasive Evaluation of Velopharyngeal Function in Cleft and Noncleft patients

Cleft Palate-Craniofacial journal, January 1998 Authors: M. Kunkel, U. Wahlmann, W. Wagner Conclusion: “Cleft palate and control patients showed overlapping ranges of velopharyngeal mobility, indicating that muscle function cannot be classified as normal or pathologic by a single acoustic measurement. An objective method of assessing velopharyngeal mobility may, however, provide a diagnostic tool for monitoring…

Normative Standards for Nasal Cross-sectional Areas by Race as Measured by Acoustic Rhinometry

Otolaryngology–Head and Neck Surgery, 1998 Authors: J. P. Corey, A. Gungor, R. Nelson, X. Liu, and J. Fredberg Conclusion: “The importance of our data is that racial differences in nasal geometry can be demonstrated by AR. Because of these differences in nasal dimensions, “normal values” for nasal volumes and cross-sectional areas should be calculated according…
