The Effects of Size and Type of Vocal Fold Polyp on Some Acoustic Voice Parameters
Background: Vocal abuse and misuse would result in vocal fold polyp. Certain features define the extent of vocal folds polyp effects on voice acoustic parameters. The present study aimed to define the effects of polyp size on acoustic voice parameters, and compare these parameters in hemorrhagic and non-hemorrhagic polyps.Methods: In the present retrospective study, 28 individuals with hemorrha...
متن کاملEffect of vocal loudness variation on the voice source
The physiological correlate of perceived vocal loudness is the overpressure of air under the glottis, or the subglottal pressure Psub. Variation of vocal loudness, i.e., of Psub has strong effects on the waveform of the transglottal airflow, also called the voice source. As the voice source is the primary sound itself, which after filtering by the vocal tract resonator is radiated through the l...

متن کاملCharacterization of the vocal fold vertical stiffness in a canine model.
OBJECTIVES/HYPOTHESIS Characterizing the vertical stiffness gradient that exists between the superior and inferior aspects of the medial surface of the vocal fold. Characterization of this stiffness gradient could elucidate the mechanism behind the divergent glottal shape observed during closing. STUDY DESIGN Basic science. METHODS Indentation testing of the folds was done in a canine model...
متن کاملCause-effect relationship between vocal fold physiology and voice production in a three-dimensional phonation model.
The goal of this study is to better understand the cause-effect relation between vocal fold physiology and the resulting vibration pattern and voice acoustics. Using a three-dimensional continuum model of phonation, the effects of changes in vocal fold stiffness, medial surface thickness in the vertical direction, resting glottal opening, and subglottal pressure on vocal fold vibration and diff...
