Larynx And Voice Physiology Under Daily Stress (1958)

This film explores the physiology of the larynx under daily stress through ultra slow-motion cinematography. It examines various vocal activities, such as singing, laughing, and talking, and their effects on the larynx. Using high-speed cameras, the film captures the intricate movements of the vocal cords, revealing new insights into voice production, including the vibratory cycles and the impact of muscle tension and air pressure. The research highlights the complexity of vocal mechanics, including the differences between chest and head registers, and the effects of everyday vocal strain.
