METHODS

In pilot study, noise pressure level was measured for 103 Mechanical factory and office workers forfull work shifts by A-weighting scale. Personal noise dosimeters, Etymothic R-200DW7 were used to measure noise level. 

RESULTS and CONCLUSION

Average noise pressure levels ofworkers were 87.56 dBA in mechanical factory, 86.29 dBA in mechanical shop and 90.24 dBA in casting shop. Noise levels in the casting shop were exceeded by 1.29-5.24 dB for Recommended Exposure Level (REL).
