Vocal Characteristics of Elderly Women Engaged in Aerobics in Private Institutions of Salvador, Bahia.

PURPOSE

To characterize the voice of elderly people engaged in aerobics.

METHODS

Collection of phonation /a:/ from 58 elderly people engaged in aerobics for perceptual voice analysis (RASATI scale) and computed acoustics (Multi Dimensional Voice Program Advanced, software of Kay Pentax®, that analyzes up to 33 measures, proposing normal ranges according to sex). The Spearman correlation test was used, with significance level of 5%.

RESULTS

The association between auditory-perceptual assessment of voice and acoustic parameters was not statistically significant but showed less vocal quality deviations. The association between acoustic measures and age was only statistically significant result for the measurement of fundamental frequency (f0) and maximum f0 (fhi). There was no correlation between time of aerobics and acoustic measures, but there was correlation of those measurements with age. There was a statistically significant positive correlation between f0 and fhi with minimal roughness and standard deviation of f0 with hoarseness, breathiness, and asthenia; jitter and shimmer measures with hoarseness, breathiness, and asthenia; noise measurements with hoarseness, breathiness, and harshness; measures of breaking voice hoarseness and breathiness; measures of voiceless segments with hoarseness and asthenia; measures of subharmonic with hoarseness; and measures of vocal tremor with breathiness, asthenia, and instability. There was a significant negative correlation between minimum f0 with breathiness; jitter measures with tension; and soft phonation index with roughness and instability.

CONCLUSIONS

Elderly women engaged in aerobics showed mostly normal voice, with most values of acoustic measures within normal and positive correlations between perceptual and auditory vocals and acoustic aspects that suggest instability, noise, and vocal tremor.
