A study was conducted on the noise level of different machines and exposure of workers to it in the Sawmill of N.W.F.P., Forest Development Corporation, Mansehra. The results of this study revealed that the noise level of all the machines in the nearest work positions and in most cases in the farthest work positions was higher than the allowable levels. The operators of machines were exposed to a higher noise level than the helpers. The daily and total expected exposure of the workers to this noise level was long enough to cause permanent hearing damage. Proper ear protection and maintenance of machines to reduce the noise level and risk of hearing disability to the workers are recommended.
