Impacto de un Programa de tres semanas de Promoción de la Salud Vocal en el lugar de trabajo en los parámetros de voz de una profesora y sus estudiantes
Impact of a Three-Week Workplace Vocal Health Promotion Program on a Teacher and Students' Voice Parameters
Resumen
Objetivo. Determinar el efecto en los parámetros de voz de los alumnos y su profesora de un Programa de tres semanas de Promoción de la Salud Vocal en el lugar de trabajo en un entorno escolar.
Métodos. Estudio longitudinal con una fase de diseño y una fase piloto. Se utilizaron grabaciones de voz de habla conectada para recopilar información sobre el funcionamiento de la voz antes y después de la implementación del programa. El programa de promoción de la salud vocal en el lugar de trabajo se implementó con dos propósitos: (1) Reducir las condiciones ruidosas dentro de las aulas que pueden causar una producción de voz a alta intensidad, lo que se ha encontrado asociado con trastornos de la voz entre profesores y estudiantes; y (2) Aumentar la conciencia sobre la relación entre el ruido y la voz dentro de las aulas.
Resultados. Se encontró que el Programa de Promoción de la Salud Vocal en el lugar de trabajo estaba estadísticamente asociado con una disminución de la frecuencia fundamental, la desviación estándar de la frecuencia fundamental, los niveles de presión sonora y la desviación estándar de la presión sonora, tanto en los alumnos como en su profesor. Sin embargo, no hubo un efecto estadísticamente significativo en la prominencia del pico cepstral suavizado.
Conclusión. Se encontró que el programa de tres semanas tenía un impacto significativo en varios parámetros acústicos, como la frecuencia fundamental y los niveles de presión sonora. Estos hallazgos destacan el potencial del programa como una intervención eficaz para mejorar la salud vocal tanto de profesores como de estudiantes. Sin embargo, la falta de un efecto significativo en la prominencia del pico cepstral suavizado sugiere que se necesita más investigación para comprender completamente el impacto del programa en la calidad vocal.
