Abstract:

This study aims to identify the noise exposure and verify if the hearing protection used by these workers is adjusted for the exposure to the impact noise, during the activities of Basic Shot Instruction in the Brazilian Army, produced by the Light Automatic Fusils - FAL, caliber 7,62mm. This study can be considered analytical, since it seeks to establish causal relations among the diverse variables involved . The qualitative approach was used, in the mapping of the working process; as well as the quantitative one, in order to analyze the data in relation to this process. It was possible to have a close estimate to reality on the basis of data collection triangulation, to include: systematic observation, half strutctured interview and experimental exercise. Based on the analyses, it can be stated these workers are exposed to a noise which ranges from 147,3 to 171 dB. Therefore, it can be concluded that the 3M 1100 hearing protection, which is largely used by military, did not provide noise reducion, since its reducing value corresponds to NRRsf at 12 dB. Thus, there is no effectiviness in the heaving protection of soldiers .
