Evaluation of Sound Environment in a Shipyard Activity

Abstract

The objective of this paper is the study of noise impact from the measurement of the sound pressure levels generated in areas and departments of a shipyard. For this, the sound level was measured and surveys were applied to 75 % of the workers. In the monitoring carried out in 33 works position of different workshops, it was found that in 42,4 % of them the existing noise levels exceed the maximum admissible values that sets the standard. On the other hand, the results of the surveys and the interviews showed that there are serious problems of noise in the environment, identifying the operation of equipment, ma-chines and the non-use of hearing protectors as the fundamental causes of noise pollution. This study showed that noise constitutes a factor of work risk in the shipyard studied, of great importance in the organization, as evidenced by the evaluations carried out to 36 workers’ Audiometric, of which 47, 2 % presented lesions. so what is needed is a set of control actions to effectively reduce risk.
