Avaliação da exposição à intensidade sonora em uma empresa de inspeção de segurança veicular

Abstract

Noise is one of the agents that cause the most undesirable effects to the health of the worker, being the main cause of the Noise-induced Auditory Loss, since many workers are exposed to high levels of noise. Therefore, the main objective of this study was to quantify the daily dose and the noise level to which the workers of a vehicle inspection company are exposed, and to conclude, according to the values presented in Annex 1 of NR 15, if the environment is unhealthy or not. For the evaluation, a dosimeter was used based on NHO 01 and NR 15. The values found for the noise level by the dosimeter according to NHO 01 and NR 15 methodology were 76,4 dB (A) and 65,8 dB (A), thus concluding that the environment, according to the two methodologies, is not unhealthy. It was also possible to verify through the variation of the noise during the working day that the most critical moments were in the inspections in which the gas and noise analyzes emitted by the exhaust of the vehicle were necessary thanks to the high rotation of the engine in which they are made.
