INTRODUCTION: Evaluating the relationship among teachers' voice symptoms, perceived voice control, and common mental disorders (CMDs) might contribute to the understanding of the relationship between vocal wear and the teacher well-being. The understanding of this relationship may also help in taking more informed clinical decisions in voice rehabilitation when considering possible perceived voice control difficulties and the need to develop voice self-control strategies. OBJECTIVE: The aim of this study was to determine the voice symptoms, perceived voice control, and CMDs in public elementary and secondary school teachers, and to analyze the relationships among these variables...

A study was undertaken to identify the effect of head flexion/extension on singing voice quality. The amplitude of the fundamental frequency (F0) and the singing power ratio (SPR), an indirect measure of Singer's Formant activity, were measured. F0 and SPR scores at four experimental head positions were compared with the subjects' scores at their habitual positions. Three vowels and three pitch levels were tested. F0 amplitudes and low-frequency partials in general were greater with neck extension, while SPR increased with neck flexion...

During vocal fold vibration, there may be a mucosal wave in the superior-inferior (vertical) direction, resulting in a convergent shape during opening and a divergent shape during closing. Most of our understanding of the converging/diverging shape of the glottis has come from studies in a hemilarynx model. Previous work has shown that vibratory patterns in the full excised larynx are different than the hemilarynx. This study characterized the dynamics of the medial glottal wall geometry during vibrations in the full excised canine larynx model...

The design specifications and experimental characteristics of a newly developed laser-projection transnasal flexible endoscope coupled with a high-speed videoendoscopy system are provided. The hardware and software design of the proposed system benefits from the combination of structured green light projection and laser triangulation techniques, which provide the capability of calibrated absolute measurements of the laryngeal structures along the horizontal and vertical planes during phonation. Visual inspection of in vivo acquired images demonstrated sharp contrast between laser points and background, confirming successful design of the system...

INTRODUCTION: The relationship between voice and auditory processing is complex and has aroused increasing scientific interest in the last decades. Little is known about the relationship between voice quality and auditory processing in individuals with and without musical experience. OBJECTIVES: To assess voice quality and auditory processing in subjects with and without musical experience. METHODS: Total 120 individuals were split into three groups: GS = singers (N = 47), GI = instrumentalists (N = 43), and NM = nonmusicians (N = 30); group GS was subdivided into GS = 20 singers only and GSI = 27 singers and instrumentalists at the same time...

OBJECTIVE/BACKGROUND: Straw phonation, a well-established method of vocal exercise, started over 100 years ago. However, some of the most basic questions about best practices remain including the ideal extension length and the ideal restriction (semiocclusion) diameter. This study aims to help answer these questions by looking at both separately, with all other variables controlled. METHODS: Four (4) straws with lengths of 5, 25, 50, and 75 centimeters and 4 restrictions with diameters of 3, 9, 15, and 21 mm were tested, separately...

OBJECTIVE: Vocal cord paralysis may result from surgical complications, trauma, tumor, or unknown causes. When both cords are affected, paramedian fixation can lead to life-threatening obstruction. Current treatments, including tracheostomy, cordotomy, and arytenoidectomy, compromise speech and swallow function to maintain a safe airway. To preserve all three critical laryngeal functions, Otolaryngologists need a solution for bilateral vocal cord paralysis that restores motion. This study uses implantable electromagnet technology to create dynamic vocal cord movement in a proof-of-concept, preliminary model...
