Abstract
Pressure-flow relationships using steady flow through polyester resin models of the larynx were investigated. Model geometry was based on x-ray data. Flow ranged from 20 to 1000 cc/s, resulting in translaryngeal pressure drops from 0.03 to 40 cm H2O. Translaryngeal pressure drop predictions from Ishizaka and Matsudaira [SCRL Monograph, No. 8 (1972)] and van den Berg, et al. [J. Acoust. Soc. Am. 29, 626–631 (1957)] fell within 37% and 50%, respectively, of the data. For an intermediate size glottis, the overall average percent difference between the measured and predicted pressure drops was less than 5% when compared with Ishizaka and Matsudaira's predictions, and less than 30% when compared with van den Berg's predictions. For a larger glottis, the corresponding percentages were 21% and 37%. We conclude that: (1) both theories underestimate the translaryngeal pressure drop, and (2) the data support the predictions of Ishizaka and Matsudaira more than the predictions of van den Berg et al.
