Using Dr. Hunter’s background in physics, acoustics and biomechanics, V-BAL is focused on examining all aspects of the voice mechanism and production, including but not limited to:
- The physiology and biomechanics of the laryngeal system;
- The acoustics of voice production;
- The effects of acoustic sound propagation in a room on listener; and
- The effects on vocal health of vocal physiology, biomechanics, acoustics and behavior.
Under Dr. Hunter’s direction, post-doctoral researchers, as well as undergraduate and graduate students, assist in recording, analyzing, and modeling voice production. In addition to the standard voice measurement tools (e.g., EGG, aerodynamic, microphones), the V-BAL laboratory has several more unique items, including spirometers, ambulatory monitors (heart rhythm), accelerometers, and devices to capture breathing, skin temperature, and blood flow. The laboratory houses a large double-walled sound booth, and has access to the department’s anechoic and reverberation chambers.
Funding for V-BAL has come from various national and private agencies including the National Institutes of Health and Trifecta.
