   Författare :Anita McAllister; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Child voice; hoarseness; perceptual evaluation; voice characteristics; visual analog scales; voice range profiles; fundamental frequency range; dynamic range; glottal closure; stroboscopy; vocal nodules; register transitions; subglottal pressure; SPL;

   Sammanfattning : The aim of the present investigation was to study hoarseness and its perceptual, acoustic and physiological characteristics in ten-year-old children's voices. Fifty-eight children's voices were perceptually evaluated along 15 voice parameters. LÄS MER

3. 2. Hoarseness in ten-year-old children : perceptual characteristics, prevalence and etiology

   Författare :Elisabeth Sederholm; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Child voice; hoarseness; perceptual analysis; voice quality; visual analog scales; connected speech; sustained vowels; prevalence; acute hoarseness; chronic hoarseness; videolaryngoscopy; stroboscopy; incomplete glottal closure; vocal nodules; voice;

   Sammanfattning : The aim of the present investigation was to explore the occurrence of and factors related to hoarseness in ten- year-old children. In order to establish the prevalence of hoarseness in a group of normal children, a method to distinguish atypical from normal voices was introduced and the perceptual characteristics of hoarseness were identified.
