Abstract

Manufacturing industries play an important role in the economy of Malaysia. One of the manufacturing industries is metal stamping industry. Basically, the processes in the metal stamping industry are using die to cut or form a flat metal sheets into desired shape. Consequently noise is produced from the processes. Noise considered as an unwanted or undesired sound. Prolonged exposure to the noise can lead to the health problems, low productivity and low performance of workers. The aim of this study is to design a noise insulator for reducing the noise level in the metal stamping industry. This study applied a workplace observation, questionnaire survey and noise level assessment at the metal stamping workstations by using a sound level meter (SLM). A prototype design of noise insulator was developed through brainstorming among the metal stamping workers, questionnaire survey and morphological chart. Recycle papers and coconut fibers were used as materials of the noise insulator. This study conducted a noise level assessment to determine the effectiveness of the developed noise insulator. The noise levels have effectively reduced the noise level up to 17.2%. This study concluded that application of used materials such as recycle papers and coconut fibers in making of noise insulator is able to reduce noise levels in metal stamping operation. This study suggests that the real fabrication and application should be implemented in the metal stamping industry to reduce the risk of noise exposure to the workers.
