ABSTRACT
Objective: This study has established the acoustic analyses on adults and geriatrics in both male and female populations. And to compare the acoustic analyses of both male and female populations Method: Participants were 118 male and female between the age range of 30 - 60 years, without the signs and symptoms of vocal problems; Praat (6.1.16 version); Vowels /a/ /i/ and /u/.
Result: There is no significant difference (p > 0.05) for fundamental frequency (F0), harmonic to noise ratio (HNR), Jitter and Shimmer across the selected age groups (30-39; 40-49; 50-60). Gender comparison of voice characteristics shows high significant difference (p< 0.01) in fundamental frequency (F0). Whereas no difference or change in the score were noted for harmonics to noise ratio, jitter and shimmer.
Conclusion: This study, like other investigations, supports the assumption that the fundamental frequency of males increases with age. The female fundamental frequency decreases with age. The male and female voice have no significant difference among the chosen age group in statistical analysis.
