Acoustic Voice Parameters of 23 Post-Menopausal Women

A quantitative cross-sectional study of 23 post-menopausal women, analyzing acoustic voice parameters to investigate vocal aging. The data was collected using Praat software and includes measurements of fundamental frequency, jitter, shimmer, harmonic noise, and spectrographic analysis. The study was conducted by researcher Renata D’Arc Scarpel with participants from the Open University of Third Age in Salvador, Brazil.

Use Cases

• Modeling the relationship between age and fundamental frequency based on the reported statistically significant correlation (p=0.02471).
• Analyzing patterns of voice deepening using the reported percentages of women with fundamental frequency below 150Hz and between 150-217Hz.
• Investigating changes in vocal fold vibratory patterns through the jitter and shimmer parameters described in the study.
• Assessing vocal quality and potential therapy needs by examining the harmonic noise ratio, which was above 15.000 for all participants.

Strengths

• Includes specific statistical results, such as a p-value of 0.02471 for the relationship between age and fundamental frequency.
• Reports concrete sample percentages, including 13% of participants with fundamental frequency below 150Hz and 34% between 150-217Hz.
• Describes a clear methodology using Praat software version 5.2.0 for acoustic analysis on a defined cohort of 23 women.

Limitations

• Row count is unknown, which may limit suitability assessment for machine learning tasks.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect geographic bias inherent to the single study location in Salvador, Brazil.
