Status of Noise Exposure in Cement Preparation Plant - A Case Study

Noise is a compratively a newly recognised problem in the list of occupational hazards. The noise level of different types of machines in a cemetn proparation palnt was measrued during the period of three months. The different sources prducing noise levels above 90 dBA were identified and a typical frequency spectrum produced by machine when, it was in operation was recorded. Noise exposure index (NEI) were calculated and found that NEI velue is higher than the prescribed limits. The results of the sudy carried out have been presented in this paper
