Article Synopsis
- Successful computer simulations of vocal fold oscillation are being refined to better account for asymmetric vibrations and complex contact patterns.
- Two methods were used in the study: a high-fidelity computational model and physical model pressure measurements, focusing on normal vibration modes of the vocal folds.
- The results revealed diverse pressure distributions on vocal folds, revealing that simplified models may not accurately represent the complexity of airflow in cases with multiple contact points.
Vocalization in mammals, birds, reptiles, and amphibians occurs with airways that have wide openings to free-space for efficient sound radiation, but sound is also produced with occluded or semi-occluded airways that have small openings to free-space. It is hypothesized that pressures produced inside the airway with semi-occluded vocalizations have an overall widening effect on the airway. This overall widening then provides more opportunity to produce wide-narrow contrasts along the airway for variation in sound quality and loudness.

While acoustic analysis has helped determine which characteristics define various vocal genres, a discrepancy still exists in how those acoustic characteristics are perceived, described, and evaluated.
Methods: The current study recorded seven novice and four professional musical theater singers performing belt, legit, and mix vocal samples.
