Repeatability of Aerodynamic Measurements of Voice

The purpose of this study was to compare baseline aerodynamic measurements of voice to measurements repeated after a 10-minute break and a one week break.Average airflow and estimated subglottal pressure measurements were gathered from females between 18 and 24 years of age with healthy voices.Each participant's frequency and intensity was held constant during each testing session.Results indicated that aerodynamic measurements of average airflow and estimated subglottal pressure were repeatable, as there were no significant differences between mean measurements taken during each testing session.The results of this study provided support for the clinical use of average airflow and estimated subglottal pressure for voice assessments and treatment data.
