Abstract

Objective:    To describe the vocal acoustic measures of nonsmoking Filipino young adults without voice complaints at a private tertiary hospital in Quezon City; to determine if our baseline values are distributed normally and comparable to data in similar studies done abroad; and to recommend normative voice parameters which may be used as baseline data in our institution and for comparison in future studies.

Methods:

Design:  Cross-sectional study

Setting: Private tertiary hospital

Participants: A total of 70 subjects were recruited at random.

Results: Values extracted for f0, Jitter %, Jitter dB, Shimmer %, Shimmer dB and NHR showed normal distribution of results. The average vocal acoustic values found in the present study for male voices producing the vowel /a/ were fo = 130.6 ± 13.65Hz, jitter = 0.0.46 % ± 0.184, jitter dB: 37.62dB ± 16.664, shimmer %= 0.23%, shimmer dB=0.23 ± 0.67 and NHR = 0.13 ± 0.010. The average values found for female voices, producing the vowel /a/ were fo = 218.38 ± 26.192Hz, jitter = 0.87% ± 0.61, jitter dB: 34.82 ± 22.5, shimmer %= 2.72 ± 1.07 shimmer dB=0.23db ± 0.67 and NHR = 0.12dB ± 0.016. Values retrieved from this study show similar trends with other papers abroad.

Conclusions: Voice acoustic systems are composed of different recording criteria, recording instrumentations and algorithms which primarily cause the differences in the results obtained in various studies, thus precluding a single normalization. Following international recommendations for individual normalization per institution, we have obtained our own values. Our data was comparable to the results of other international studies. However further investigation is recommended in areas where possibilities of interdialectic variation may produce an effect on the outcome of the study.
