Impact of Noise Pollution on Worker's Health of Cement Plant

Noise is a dangerous form of environmental pollution. It can be defined as sound without agreeable quality or as unwanted sound. In cement industry, the problem of noise has got accentuated due to increased mechanization. The prolonged exposure to high levels of noise (>90 dBA) proves harmful and may culminate in Noise Induced Hearing Loss (NIHL). Not only this, it also brings other physiological disorders which could lead to irritability and lowering of efficiency. Keeping this into the mind, before initiating any sort of administrative, engineering and medical measures against this noise hazards, a systematic noise survey are essential. These help in identifying the noise pollution sources and quantifying the risk exposure of workers. And then accordingly effective anti-noise measures can be formulated and implemented. The present paper discusses the results of the noise studies in cement plant and analyses the leq(dBA) produced by different machinery in this plant. It also focuses the adverse effects of noise on worker’s health as well as the audiometric study of the workers. Lastly some suggestions has beenmentioned for protecting the worker’s health from noise
