Smoothed Cepstral Peak Prominence: A Comparison Between Dysphonic and Non-dysphonic Mexican Adults Employing the Praat Software.

Background Acoustic vocal analysis provides objective and measurable values for various voice parameters, such as fundamental frequency (F0), shimmer, jitter, and the noise-to-harmony ratio (NHR). In severely dysphonic patients, who present increased variability in glottic cycles and abnormalities in vocal intensity, conventional acoustic analysis is an unreliable predictor of dysphonia. The logarithmic transformation of the vocal spectrum (cepstrum) allows capturing the signal without relying on recording technique, frequency, or vocal intensity.

Age adjusted normative data for Video Head Impulse Test in healthy subjects.

Purpose: This study aims to assess the effect of age in vestibulo-ocular reflex (VOR) gain measured by Video Head Impulse Test (VHIT) and to present normative data of VOR gain, median gain at 40, 60, 80 and 0-100 ms, and gain asymmetry according to decades of life in healthy subjects.
