EVALUVATION OF NOISE LEVEL AND ITS ADVERSE EFFECT IN METAL DIE MANUFACUTURING INDUSTRY

Noise generated from industries is a prominent health problems and social problems and it causes of acute and chronic diseases such as cardiovascular dieses, acoustic trauma, noise induced hearing loss, hindrance communication between the employees, fatigue and loss of concentration. The noise induced hearing loss affects the both ears simultaneously. This paper is related to study about noise in metal die manufacturing industry by using sheet metal works in various operations. The power press is playing major role in sheet metal die manufacturing industry which is more noise generating machine. Several types of noises are observed from the various machines involved in sheet metal works exceeding the OSHA TWA (Time weighted average) standards. Noise induced hearing loss and environment pollutions are the main cause of such kind of industries. Goal of the study is to evaluate the noise level in those small scale industries and suggested to alleviate the noise level and its annoyances to development of safe and healthy work environment for the workers in press tool industries
