The Study Of The Application Of Noise Mapping Using Golden Surfer Software To Control Noise

Machines and equipment or work processes that make noise. Evaluation of noise intensity is carried out by making a map describes the distribution pattern from 278 measurement points then processed with surfer software, which becomes basic information to protect workers risk hearing loss. After measuring analyzing data, level ranged lowest 41.0 dBA, highest 101.9 dBA. From map, it can be seen main sources are in workshop area, corn intake & dryer generator area bagging off area. Noise control efforts have been engineering controls, administrative controls form rotation, Standard Operating Procedures, training, safety signs use ear protective for earplugs earmuffs.
