Toles, Laura E.; Seidman, Ariana Y.; Hillman, Robert E.; Mehta, Daryush D. – Journal of Speech, Language, and Hearing Research, 2022
Purpose: This study aimed to determine whether a simplified, and potentially more stable, acoustic-aerodynamic voice outcome ratio (ratio of sound pressure level [SPL] to subglottal pressure) is comparable to a traditional vocal efficiency measure (ratio of acoustic power to the product of average subglottal pressure and average phonatory airflow)…

Van Stan, Jarrad H.; Mehta, Daryush D.; Ortiz, Andrew J.; Burns, James A.; Toles, Laura E.; Marks, Katherine L.; Vangel, Mark; Hron, Tiffiny; Zeitels, Steven; Hillman, Robert E. – Journal of Speech, Language, and Hearing Research, 2020
Purpose: Previous work using ambulatory voice recordings has shown no differences in average vocal behavior between patients with phonotraumatic vocal hyperfunction and matched controls. This study used larger groups to replicate these results and expanded the analysis to include distributional characteristics of ambulatory voice use and measures…

Van Stan, Jarrad H.; Ortiz, Andrew J.; Cortes, Juan P.; Marks, Katherine L.; Toles, Laura E.; Mehta, Daryush D.; Burns, James A.; Hron, Tiffiny; Stadelman-Cohen, Tara; Krusemark, Carol; Muise, Jason; Fox-Galalis, Annie B.; Nudelman, Charles; Zeitels, Steven; Hillman, Robert E. – Journal of Speech, Language, and Hearing Research, 2021
Purpose: The purpose of this study was to obtain a more comprehensive understanding of the pathophysiology and impact on daily voice use of nonphonotraumatic vocal hyperfunction (NPVH). Method: An ambulatory voice monitor collected 1 week of data from 36 patients with NPVH and 36 vocally healthy matched controls. A subset of 11 patients with NPVH…
