title: Comparison of maximum flow declination rate: children versus adults.
abstract: The measure of maximum flow declination rate (MFDR) and location of MFDR provided information regarding the laryngeal mechanism's response to vocal intensity variation as a function of gender and age. Results indicate (a) increases in MFDR values as vocal intensity increases for both children and adults, and (b) higher MFDR values for men versus women and children; no gender difference was found for the children. Results for location of MFDR indicate (a) the location of MFDR to be highest for the loud-intensity production as compared with soft- and comfortable-intensity productions, and (b) the location of MFDR in women to be higher than in men. No gender difference was found for the children.
