Belting by Trained Singers Compared With Shouting by Untrained Nonsingers: How Do They Differ?

Trained belters demonstrated greater efficiency, producing similar acoustic output to the shouters, but with less subglottal power. This result may reflect differences in vocal skill. Somewhat counterintuitively, some economy estimates were lower in male belters than in shouters. This was due to the trained males' significantly higher P_sub and CQ. It is questionable whether the economy estimates approximating vocal fold impact stress based on CQ and P_sub perform well in high-intensity phonation.
