“…Simultáneamente, en la muestra estudiada el incremento de ambos parámetros fue proporcional al paso del tiempo. Esta particularidad se trataría de una adaptación natural a la rigidez que adquiere la cubierta cordal producto al mismo uso y, además, explica porque una vez terminada la tarea de sobrecarga las características acústicas empleadas durante su ejecución se mantienen en el tiempo (Remacle et al, 2017).…”

“…El aumento progresivo de tono e intensidad a medida se ejecutó la tarea de sobrecarga vocal, se describe como parte del comportamiento adaptativo que existe durante la fatiga vocal (Remacle et al, 2017). A medida el sujeto percibe su voz cansada, inicia un círculo compensatorio que solicita más esfuerzo y, por consiguiente, un aumento de los parámetros mencionados (McCabe & Titze, 2002).…”

La sobrecarga es una de las etapas del continuo de carga vocal. Actualmente, se considera que su investigación permite una mejor comprensión de la patología y sintomatología funcional de la voz. El objetivo de este trabajo fue analizar las consecuencias laringoscópicas, electroglotográficas, acústicas y sintomatológicas producidas por la sobrecarga vocal en mujeres con voces sanas y no entrenadas. Se examinó el comportamiento acústico, laringoscópico, electroglotográfico y sintomatológico de 30 mujeres que se sometieron a una tarea de sobrecarga vocal caracterizada por la lectura ininterrumpida de un texto durante 60 minutos, cuya intensidad fluctuó entre los 75 y 85 dB. A nivel laringoscópico, se observó mayor vascularización, aumento de la compresión supraglótica y cambios en la amplitud, simetría y onda mucosa. Acústicamente, se evidenció incremento significativo en la frecuencia fundamental e intensidad vocal. En la electroglotografía, el cociente de cierre y la fase abierta y cerrada disminuyeron significativamente, mientras que a nivel sintomatológico, la totalidad de la muestra expresó al menos un síntoma de fatiga vocal. En conclusión, los hallazgos observados son expresiones de la fatiga del mecanismo tiroaritenoideo y de la inflamación aguda de la cubierta cordal.

“…According to Hunter et al (2020), vocal demand response depends on individual attributes, which may partially explain the disparate vocal injuries in vocalists facing a similar vocal demand. Given the scenario of a workday, Remacle et al (2018) evaluated the inter-and intra-subject variability of teachers' responses to vocal demand in terms of vocal acoustic parameters measured at the beginning and at the end of 66 teaching days. They Factors predicting teachers' vocal acoustic parameters This is a post-peer-review, pre-copyedit version of an article published in International Archives of Occupational and Environmental Health.…”

“…The absence of a clear link between voicing time, on one hand, and voice fo and SPL, on the other, might be due to the variability of the teachers' response to vocal demand. The changes in the voice acoustic parameters following a workday are teacher-specific (Remacle et al 2018).…”

“…This had a significant effect on their voice frequency measured over the week, since these teachers' mean fo was 11 Hz (or 1.7 semitones) lower than that of the others. In their typology of teachers' vocal demand response, Remacle et al (2018) identified three patterns. Regarding the frequency changes from morning to evening, the first and second patterns were both characterized by an fo increase, interpreted respectively as an appropriate adaptation to vocal demand and as a change to a hyperfunctional voice.…”

Purpose: To identify the factors affecting teachers' vocal acoustic parameters, with the aim of detecting individuals at risk of phonotrauma. Method:The voicing time, voice sound pressure level [SPL] and fundamental frequency [fo] of 87 teachers were measured during one workweek using a voice dosimeter. We retrospectively investigated the impact of 10 factors (gender, age, teaching experience, teaching level, tobacco, gastro-esophageal problems, nonoccupational voice activity, voice education, past voice problems, and biopsychosocial impact of voice problems measured using the Voice Handicap Index [VHI]) on each voice parameter.Results: None of the above factors affected voicing time or SPL. fo depended significantly on gender, teaching level, nonoccupational voice activity and VHI score. Specifically, fo was higher in women (Δ = 69 Hz), in individuals without nonoccupational voice activities (Δ = 11 Hz), and in individuals with a lower VHI score (increase of 0.7 Hz for each additional point). For females, post hoc comparisons revealed a substantial impact of teaching level on fo: university instructors had deeper voices than kindergarten (Δ = 66 Hz), elementary (Δ = 52 Hz), or secondary teachers (Δ = 41 Hz).Conclusions: Since higher fo increases the mechanical stress related to vocal fold vibration, the screening and prevention of phonotrauma should focus primarily on women, particularly those who teach at lower levels, and teachers with more self-rated voice problems. The lower fo of teachers who engage in nonprofessional voice activities may suggest acute inflammation or muscle fatigue due to voice overload.

Purpose The authors aim to review available reports on the potential effects of masks on voice and speech parameters. Methods A literature search was conducted using MEDLINE and Google Scholar databases through July 2021. Several targeted populations, mask scenarios and methodologies were approached. The assessed voice parameters were divided into self-reported, acoustic and aerodynamic. Results It was observed that the wearing of a face mask has been shown to induce several changes in voice parameters: (1) self-reported—significantly increased vocal effort and fatigue, increased vocal tract discomfort and increased values of voice handicap index (VHI) were observed; (2) acoustics—increased voice intensity, altered formants frequency (F2 and F3) with no changes in fundamental frequency, increased harmonics-to-noise ratio (HNR) and increased mean spectral values in high-frequency levels (1000–8000 Hz), especially with KN95 mask; (3) aerodynamics—maximum phonatory time was assessed in only two reports, and showed no alterations. Conclusion Despite the different populations, mask-type scenarios and methodologies described by each study, the results of this review outline the significant changes in voice characteristics with the use of face masks. Wearing a mask shows to increase the perception of vocal effort and an alteration of the vocal tract length and speech articulatory movements, leading to spectral sound changes, impaired communication and perception. Studies analyzing the effect of masks on voice aerodynamics are lacking. Further research is required to study the long-term effects of face masks on the potential development of voice pathology.

Vocal Change Patterns During a Teaching Day: Inter- and Intra-subject Variability

Abstract: The observed variety of vocal patterns during the workday emphasizes the need to study this phenomenon individually and target different types of behaviors to develop tailored prevention and treatment methods.
