The relationship of national laws that prohibit child marriage with the prevalence and adolescent birth is not well understood.Data from Demographic Health Surveys Child Marriage Database created by MACHEquity program at McGill University were used to examine between consistently set age for girls 18 or older teenage childbearing in 12 Sub-Saharan African countries. Countries considered have consistent against if they required females be marry, marry parental consent sex. Associations two...
Purpose: This study investigated the influence of tube phonation into water on vocal fold vibration.Method: Eight participants were analyzed via high-speed digital imaging while phonating a silicon with free end submerged water. Two test sequences studied: (1) pre, during, and post 5 cm water; (2) cm, 10 18 Several glottal area parameters calculated using phonovibrograms.Results: The results showed individual differences. However, certain trends possible to identify based similar found for...
The results of previous cross-section studies suggest that childhood hearing impairment may lead to parental psychosocial stress. present study investigated whether modifications in psychic state can be ascertained connection with the child's treatment events and speech status, a prospective design. Data were available on 116 fathers mothers regarding preâcochlear implant examination or aid fitting their child. In course treatment, quality life improved from low normal level. Among...
Measured values of the amplitude voltage spike for different current impulses are presented. It is shown that this peak in nanosecond-range and can only be measured with a coaxial measuring arrangement having bandwidth some MHz. The results show clearly 10% related to characteristics ZnO used metal oxide (MO) surge arresters. initial influenced by composition material.

Tenor singers may reach their top pitch range either by shifting from modal to falsetto register or using so-called 'voix mixte'.In this study, dynamic real-time MRI of 8 frames per second was used analyze the vocal tract profile in 10 professional opera tenors, who sang an ascending scale C4 (262 Hz) A4 (440 on vowel /a/. The included transition and applied both techniques different takes.Modal changes were associated with only minor modifications, including elevation tilting larynx a...
Human voice production at very high fundamental frequencies is not yet understood in detail. It was hypothesized that these are produced by turbulences, vocal tract/vocal fold interactions, or oscillations without closure. Hitherto it has been impossible to visually analyze the mechanism due technical limitations. Latest high-speed technology, which captures 20 000 frames/s, using transnasal endoscopy applied. Up 1568 Hz human folds do exhibit with complete Therefore, recent results suggest...
Introduction Dynamic MRI analysis of phonation has gathered interest in voice and speech physiology. However, there are limited data addressing the extent to which articulation is dependent on loudness. Material Methods 12 professional singer subjects different classifications were analysed concerning vocal tract profiles recorded with dynamic real-time 25fps pitch loudness conditions. The asked sing ascending scales vowel /a/ three conditions (comfortable = mf, very soft pp, loud ff,...
The spread of breathing air when playing wind instruments and singing was investigated visualized using two methods: (1) schlieren imaging with a mirror (2) background-oriented (BOS). These methods visualize airflow by visualizing density gradients in transparent media. professional woodwind brass instrument players, as well classical trained singers were to estimate the distances air. For better comparison consistent measurement series, single high note, low an extract musical piece...
Abstract Voice production of humans and most mammals is governed by the MyoElastic-AeroDynamic (MEAD) principle, where an air stream modulated self-sustained vocal fold oscillation to generate audible pressure fluctuations. An alternative mechanism found in ultrasonic vocalizations rodents, which are established aeroacoustic (AA) phenomenon without vibration laryngeal tissue. Previously, some authors argued that high-pitched human vocalization also produced AA principle. Here, we investigate...
Zusammenfassung Hintergrund Die Corona-Krise beeinflusst nicht nur das professionelle Handeln, sondern auch die Lehre an den Universitäten. Schlagworte wie „E-Learning“ und „Digitalisierung“ suggerieren Möglichkeit innovativer, ad hoc verfügbarer Lösungsansätze für in der aktuellen COVID-19-Situation. aktuelle Umstellung auf digitale ist aber primär durch eine didaktische Sinnhaftigkeit oder institutionelle Strategie, äußere Notwendigkeit geprägt. Ziel Arbeit war Erfassung Lehrsituation...
Changes of vocal tract shape accompanying changes register and pitch in singing have remained an unclear field. Dynamic real-time magnetic resonance imaging (MRI) was applied to two professional classical singers (a tenor a baritone) this pilot study. The sang ascending scales from B3 G#4 on the vowel /a/, keeping modal throughout or shifting falsetto for highest pitches. results show that these made few minor modifications when they changed some clear kept register. In case baritone...
Music performance anxiety (MPA) represents a high challenge every vocal performer has to meet. MPA can be defined on continuum going from low level. and its phenomena considered in terms of four levels: affect, cognition, behaviour, physiology. A study carried out seven opera singers two instrumentalists during situations showed highly elevated values for the performers' heart rate blood pressure. This study, as several others, yielded no clear evidence pointing correspondence between level...
