Abstract
Studies in airflow during speech production typically use a pneumotachographic mask system to measure expired airflows. Accurate measures of airflow using the Glottal Enterprises MSIF-2 aerodynamic system require a complete seal of the mask rim to the face. Literature frequently cites mask rim leaks as causing flow measure inaccuracies, but quantitative studies of inaccuracies are needed. Prior work (May & Scherer, in press) provided a general empirical equation relating mask rim leak flow, the cross sectional area of the rim leak, and upstream airflow. The current empirical bench research extends this DC flow work to an AC flow situation as in the case of vibrato and/or tremor using 3 and 6 Hz, 2 leak areas, 50 and 200 cm3/s peak-to-peak variations, and an upstream flow of 200 cm3/s. Results: smaller leak area, higher AC frequency, and higher AC airflow extent resulted in the lowest mask rim leak airflow.
