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 کاملVisualizing collagen network within human and rhesus monkey vocal folds using polarized light microscopy.
OBJECTIVES Collagen fiber content and orientation affect the viscoelastic properties of the vocal folds, determining oscillation characteristics during speech and other vocalization. The investigation and reconstruction of the collagen network in vocal folds remains a challenge, because the collagen network requires at least micron-scale resolution. In this study, we used polarized light micros...
متن کاملInteraction of vocal fold and vocal tract oscillations
We study the mechanical feedback coupling between the human vocal folds and vocal tract (VT) by simulating fundamental frequency glides over the lowest VT resonance. In the classical source– filter theory of speech production, the vocal folds produce a signal which is filtered by the resonator, vocal tract without any feedback. We have developed a computational model of the vocal folds and the ...
متن کاملDynamic digital image correlation of a dynamic physical model of the vocal folds
An experimental study of the vibratory deformation of the human vocal folds was conducted. Experiments were performed using model vocal folds made of soft silicone rubber, and an air supply system. The model self-oscillated at fundamental frequencies and flow rates typical of the human folds. Time-averaged mass flow rates and transglottal pressures were measured along with the sound pressure up...
متن کاملPharmacokinetics and safety of human recombinant hepatocyte growth factor administered to vocal folds.
OBJECTIVES/HYPOTHESIS Previous animal studies demonstrated that hepatocyte growth factor (HGF) has the potential to regenerate scarred vocal folds. In addition, HGF is now produced under a good manufacturing practice (GMP) procedure. Therefore, human clinical trials of HGF are warranted in patients with vocal fold scarring. In the current study, we investigated the pharmacokinetics and the loca...
