Abstract :
A system is described for the analysis of recordings made on infants suffering from a condition of the airway known as stridor. The method is based on the use of a digital filterbank designed to model the critical band response of the human ear. This physiologically based filterbank uses 145 fourth-order bandpass filters whose center frequencies are spaced on a perceptual scale as determined by the critical band theory over the range 100 Hz to 6.4 kHz. Results from three recordings are illustrated and discussed
