Abstract:

AIM: To analyze vocal parameter extension, frequency, and intensity in elderly women who sing in the choir. METHOD: The participants were 25 elderly womenwho were singers in the choir at the Messianic Church in So Paulo, Brazil. These participants were between 63-82 years of age (mean age, 71 years; standard deviation, 5.22). Each subject was required to count from 20 to 30 in a voice ranging from low, medium, strong, to very strong intensity. These speech samples werefedinto the Vocalgrama software that aids in speech extension profile analysis. The following parameters were analyzed: minimum and maximum frequency and intensity and spoken voice extension in Hertz (Hz) and half-tones (HT). The singers were divided into 2 groups according to their age: G1 from 63-71 years of age and G2 from 72-82 years of age. RESULTS: In G1, the minimum speech frequency was 134.82 Hz; maximum frequency 349.96 Hz; extension 215.14 Hzand 16.41 HT; minimum intensity 40.28 dB, and maximum intensity 95.50 dB. In G2, the minimum speech frequency was 137.28 Hz; maximum frequency 348.59 Hz; extension 211.30 Hz and 16.05 HT 16.05; minimum intensity 40.63 dB, and maximum intensity 94.35 dB. CONCLUSION: G1 had a higher maximum frequency, extension, and intensity thanG2, and the last group had a higher minimum frequency. There was no difference between the minimum intensities of both the groups. The data presents evidence on the effects of presbyphonia.
