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 summarized 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.
2) Placing No. 3a was associated with a moderate glottic closure and pulmonary pressure. The supraglottis was not very nassow. The estimated maximum volume velocity was high aut mean airflow rate was moderate.
3) Placing No. 3b was accompanied by a soft glottic closure, a wide supraglottic space and a low pulmonary and subglottic pressure. The estimated maximum volume velocity was high but the mean airflow rate was moderate.
4) Placing No. 4 and 5 were characterized by a glottic adjustment for falsetto. The estimated maximum volume velocity and mean airflow rate were rather low.
5) Placing No. 6 was associated with a fairly tight glottis closure, a moderate pulmonary pressure, and a high SPL. The estimated maximum volume velocity was high but the mean airflow rate was low.
