ABSTRACT
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.
