Abstract
Esta investigación tiene el propósito identificar las características
vocales y la percepción de la voz de los colaboradores de la Municipalidad
de Lurigancho – Chosica al utilizar mascarilla de protección facial de tela
en tiempos de COVID-19, para detectar alguna dificultad en la voz y
desarrollar programas preventivos. Se utiliza un diseño no experimental de
tipo descriptivo con 64 colaboradores, donde se valida un cuestionario, se
usa el PRAAT, el IDV y el protocolo de Análisis Perceptivo Auditivo. En
cuanto a las conclusiones, no existe relación entre la autopercepción de la
voz que tienen los colaboradores y el análisis perceptivo-auditivo.
Asimismo, el 72% presenta una voz adecuada, el tipo de respiración
prevalente es clavicular y el modo, nasal. La incoordinación
pneumofonoarticulatoria es de 22 % y prevalece la resonancia oral. El Pitch
medio predomina en ambos géneros y las frecuencias en varones es de
promedio 130 Hz sin mascarilla y 132 Hz con mascarilla, con la diferencia
de 2 Hz; y, en las mujeres con 203 Hz sin mascarilla y 204 Hz con
mascarilla, con 1 Hz de diferencia. La intensidad en varones es 71 dB sin
mascarilla y 68 dB con mascarilla; y en mujeres es 70 dB sin mascarilla y
67 dB con mascarilla, diferenciándose en 3 dB en ambos. El 17 % de los
colaboradores evaluados no percibe ninguna sintomatología en su voz y
según el IDV, la funcional es de mayor prevalencia.
The purpose of this research is to identify the vocal characteristics and voice perception of the collaborators of the Municipality of Lurigancho - Chosica when using fabric face masks in times of COVID-19, in order to detect any difficulty in the voice and develop preventive programs. A nonexperimental design of descriptive type is used with 64 collaborators, where a questionnaire is validated, the PRAAT, the IDV and the protocol of Auditory Perceptive Analysis are used. As for the conclusions, there is no relationship between the collaborators' self-perception of voice and the perceptual-auditory analysis. Likewise, 72% present an adequate voice, the prevalent type of breathing is clavicular and the mode, nasal. Pneumophonoarticulatory incoordination is 22% and oral resonance prevails. The average Pitch predominates in both genders and the frequencies in males are on average 130 Hz without mask and 132 Hz with mask, with the difference of 2 Hz; and, in females with 203 Hz without mask and 204 Hz with mask, with 1 Hz of difference. The intensity in men is 71 dB without mask and 68 dB with mask; and in women it is 70 dB without mask and 67 dB with mask, with a difference of 3 dB in both. Seventeen percent of the evaluated collaborators do not perceive any symptomatology in their voice and according to the VDI, the functional one is more prevalent.
