Ultra-high-speep cinematography, measurements of airflow and sound pressure level (SPL) were conducted with nine singing voice samples produced by a professional tenor singer. The voice samples were chosen on the basis of Husler's placing. Estimated volume velocity curve, estimated maximum volume velocity, maximum glottic width, mean airflow rate, open quotient, speed quotient, speed index, SPL, distance between the false folds were determined and related to voice quality. The results were

... rized as follows: 1) Placing No. 2 was characterized by a tight glottic closure, a narrow supraglottic space, a high pulmonary and subglottic pressure, and a high SPL. The estimated maximum volume velocity and mean airflow rate were also very high.
