A study is reported investigating the relationship between modality (major/minor) and dynamics (piano/forte) on four affects – as evident in the content of musical lyrics. Forty solo vocal works were sampled: 10 in the major mode with a loud (forte) dynamic level, 10 in the major mode with a quiet (piano) dynamic level, 10 in the minor mode with a loud dynamic level, and 10 in the minor mode wi...

background: tuberculosis of the larynx is a rare form of tuberculosis. patients usually present with hoarseness or dysphagia and other nonspecific constitutional symptoms like fever or localized pain. in this study, we present a case of primary vocal cord lesion with tuberculosis. case presentation: a 72 year old man presented with hoarseness of voice, low grade fever, and night sweating with i...

OBJECTIVES/HYPOTHESIS Office-based procedures have been proposed for the treatment of vocal polyps, including indirect laryngoscopic surgery and angiolytic laser photocoagulation. Our previous report documented good treatment outcomes by combining the two aforementioned procedures. This study was intended to further compare the treatment outcomes of office transnasal vocal fold polypectomy (VFP...

Simulation of the phonatory flow-structure interaction has been conducted in a three-dimensional, tubular shaped laryngeal model that has been designed with a high level of realism with respect to the human laryngeal anatomy. A non-linear spring-based contact force model is also implemented for the purpose of representing contact in more general conditions, especially those associated with thre...

This study, based on the measurement of three-dimensional (3-D) vocal tract shapes during fricative consonant phonation, presents a realistic modeling of a human speech production system. The 3-D shapes of a vocal tract and a dental crown were measured using Magnetic Resonance Imaging (MRI). A male subject was asked to produce the fricatives /s/ and /6/ while wearing a dental crown plate that c...

OBJECTIVES/HYPOTHESIS NR4A1 was recently identified as an endogenous inhibitor of transforming growth factor (TGF)-β-induced fibrosis, and the role of this nuclear receptor has not been elucidated in tissue health or the response to injury in the vocal folds. Given the clinical implications of vocal fold fibrosis, we investigated NR4A1 expression during vocal fold wound healing in vivo and the ...

School teachers have an elevated risk of voice problems due to the vocal demands in the workplace. This manuscript presents the results of three studies investigating teachers' voice use at work. In the first study, 57 teachers were observed for 2 weeks (waking hours) to compare how they used their voice in the school environment and in non-school environments. In a second study, 45 participant...

Adult animals can eavesdrop on behavioral interactions between potential opponents to assess their competitive ability and motivation to contest resources without interacting directly with them. Surprisingly, eavesdropping is not yet considered as an important factor used to resolve conflicts between family members. In this study, we show that nestling barn owls (Tyto alba) competing for food e...

introduction: unilateral vocal cord paralysis (uvcp) is not an uncommon finding. several procedures are available to manage glottal insufficiency. we conducted a clinical trial to evaluate the outcome of fat injection laryngoplasty.   materials and methods: liposuctioned lower abdomen fat was injected for augmentation of paralyzed vocal cord in 20 patients with uvcp. autologous fat was harveste...

BACKGROUND Voice problems are more common in teachers due to intensive voice use during routine at work. There is evidence that occupational disphonia prevention programs are important in improving the quality voice and consequently the quality of subjects' lives. AIM To investigate the impact of educational voice interventions for teachers on quality of life and voice. METHODS A longitudin...
