Thirty females between the ages of 18 and 25 years with healthy voices were recruited from the Oxford, Ohio area to participate in this study. Aerodynamic measures of the voice were obtained using the Phonatory Aerodynamic System. The same protocol was followed for all three sessions, with average airflow and estimated subglottal pressure being examined during loud, comfortable, and soft phonatory levels. Results of the study indicated that mean average airflow and mean estimated subglottal pressure measures are consistent over short-term and long-term periods. The study also found that subject perceived changes of intensity variation had a significant effect on estimated subglottal pressure measures, but not on average airflow measures. The results of this study support the repeatability of aerodynamic measures, the reliability of their use, and information that contributes to clinical assessments of voice disorders. 2009-04-13 English text Miami University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=miami1239321162 http://rave.ohiolink.edu/etdc/view?acc_num=miami1239321162 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
