Abstract

Background: Noise, is one of the most common sources of occupational diseases, which has a physical nature studied in various forms. Since few studies have been conducted on some of these forms, such as the calculation of sound spectrum level, the present study was done to assess the balance of spectrum in Crepenaz textile factory.Methods: In this study, first, Pykanol Hall in CREPENAZ FACTORY, which is the most important location in terms of noise production, was set up into 286 sound stations with 6 in 6 meters wide for each one. In addition, noise levels have also been studied. The sound pressure is measured using a sound level meter and subsequently frequency analysis was performed in the stations with the level of noise more than 85 dB. In the third step, with calculation of the balance of spectrum in these stations, an opportunity was provided to facilitate the comparison of the extent of the risk exposure in the stations.Results: Of 286 sound stations, only 73 were active. In seven stations, the SOUND PRESSURE LEVEL was more than 85 dB. A comparison between sound levels was subsequently provided and carried out.Conclusion: The present study demonstrated a distribution of SOUND PRESSURE LEVELs in the different parts of the factory. The sound control in this work place was provided through determining the stations with high sound levels and calculating the sound levels.
