Abstract—This paper refers to a study and effect of Noise Dose in a small scale manufacturing sheet metal industry situated in West Bengal of India. Different noise related data are taken from individual machine and compare with the different noise related variables with Leq, Lav, LAE and TWA (Time weighted average). Noise induced hearing loss (NIHL), which is creating highly environmental pollution, causes the leading occupational disease. For the development of agerelated hearing loss, it creates a major contribution. A noise related hearing loss reduction for workers is proposed in this paper.

Index Terms—Precision dosimeter, Small Scale Industry, noise exposure, effect of noise.
