Abstract
This study was carried out to characterize the voice of the elderly women engaged in aerobics through spectrographic analysis. The vocal emission /a:/ of 58 elderly women engaged in aerobics for the spectrographic analysis of broadband(BBS) and narrowband (NBS) was collected, through the Real-Time Spectrogram of KayPENTAX program, that provides information about the glottal source, the position of the vocal tract and the characteristics of vowels and consonants. ANOVA (Análise de Variância) test was used for associations and Pearson correlation test with a significance level of 5%. To the BBS, the elderly women had medium intensity of the tracing color of the formants (Fs), low presence of noise, and medium definition of F1 and F2. There was a medium defining F3 and F4 and regularity for age 60years, medium definition F4 and high regularity of the tracing for 70years, and medium definition of F3 and F4 and regularity of the tracing for 80years. For the NBS, the elderly women had medium intensity of tracing color, little presence of noise, harmonic substitutions by noise and subharmonic; 60 and 80years had medium definition of harmonics and regularity of tracing and high definition; and regular for 70years. For 70 and 80years, there was a presence of harmonics and medium presence for 60years. There was a negative correlation between F2 and the group of 60years and F3 with the general age. Even with myofunctional, structural, and functional changes of the larynx caused by advancing age, which may affect the vocal characteristics, the elderly women of this study showed few changes in tracing spectrogram.
