Efectos del ruido en la calidad vocal de docentes de Instituciones Educativas en Cúcuta, Norte de Santander.

Abstract

INTRODUCTION: he objective of the research was to identify the effect of noise on vocal quality through the acoustic analysis of voice in teachers of educational institutions in Cúcuta, Norte de Santander. METHODS: A descriptive study with a quantitative approach, with a total population of 71 teachers, who underwent: Audiometry, acoustic analysis of the voice, the vocal disability index protocol and sonometryRESULTS Which gave an average of noise for each area from 62 to 65 dB and alteration in local JITTER was identified to 25 teachers of the 57 evaluated, JITTER = 0.307 + 0.015 age-0.126 sex-0.012 service time +0.018 hours worked -0.008 noise. ANALYSIS AND DISCUSSION: n the regression models, it gave R2 = 18.6%, which indicates that, as a whole, the independent variables explain in 18.6% the variability that occurs in the variable JITTER, which is our dependent variable. Although this equation is not the best for predictive purposes, the relationships we obtained are in correspondence with the theoretical postulates of the voice. CONCLUSIONS: There was no variability in noise measurements, their percentages were homogeneous, preventing a predictive registration with the regression model, but according to the literature it is said that noise is a factor that significantly influences vocal quality as long as it is accompanied of other exposure factors.
