Acoustic Analysis of Normal Voice Patterns in Pakistani Adults

This study was designed to find out normative acoustic measures of adults in Pakistan. Age and gender differences in these parameters were also studied. The study variables include fundamental frequency, absolute jitter, relative jitter, relative average perturbation, 5-point period perturbation quotient perturbation quotient, jitter average absolute difference between consecutive periods, divided by the average period, shimmer local, shimmer decibel, three-point amplitude perturbation quotient, five-point amplitude perturbation quotient, average absolute difference of consecutive differences between the consecutive periods' amplitudes, and harmonics-to-noise ratio.
