| Abstract | ||
| This study was conducted to demonstrate the industrial noise levels in the carpentry factories in the city of Kirkuk generated by various woodworking machines targeting to assess the magnitude of daily noise exposure by workers and how to reduce their harmed effects . Several types of manufactured wood panels ( Particleboard , Plywood , Glued Laminated Timbers , Medium density fiberboard MDF , Panels of Eucalyptus camaldulensis ) have been used for isolating noise sources as containers box and soundproof wall inside the factories buildings in order to reduce the noise levels. The results of current study showed that the noise caused by Carpentry Group’s machine ( saws cutting wood disc , lathe and attached soften machine ) reach 96 dB at its peak showing superiority on the other machines available in the carpentry factories. The use of MDF panels as containers box around the noise source led to reduce noise to 89 dB comparing to the other wooden panels besides they reduced the noise to 90.3 dB when they used as soundproof wall. Moreover , the Specific Gratify ( SG ) of the panels was also used as an indicator of panels' effectiveness to reduce the noise . | ||
