Noise pollution: hearing loss in employees at the Cochabamba bus station.

Abstract

Introduction: Noise pollution is an issue that affects people's hearing health. Health experts warn that a noise level of 55 dB should be the desirable upper limit outdoors, not considering the duration of exposure. In public spaces, noise has currently become a risk factor that, when constantly exposed to, alters health. In this regard, the research aimed to establish the prevalence of hearing loss in employees and the noise level at the Cochabamba Bus Terminal. Methodology: An observational, descriptive cross-sectional cohort study was conducted, involving 86 employees. Inclusion criteria were employees who had been working for at least one year and were over 18 years old; the Rinne test was conducted, and a Sound Level Meter brand sound meter was used to quantify the sound level. Results: The findings report that, of the total study population, 3.4% show a positive Rinne test (+) and that noise levels exceed permissible limits. Discussion: Therefore, permanent exposure impacts the auditory health of the population. In this context, it is necessary to promote timely preventive actions, implement hearing protectors, promote a healthy lifestyle, and ensure that any hearing manifestations should be addressed by specialized professionals in the field.
