ABSTRACT
Communication and entertainment are the critically essential components of life based on sound. It is pleasant at a low tone, but at a higher tone, it is alarming and very unpleasant and referred to as “noise”. Unexpected progress in technology, modern urban life, and overpopulation has led to noise pollution at a critical level. Industrialization, engineering establishments, printing presses and metal works, for example, contribute significantly towards noise pollution. Noise is creating a severe health hazard, and it affects human beings at physical, physiological, as well as psychological levels. Depending on the source, scale, and effect of noise, we have to determine different measures to control it effectively. There is a direct proportionality between parameters responsible for industrial noise and vibrations. So, by controlling or reducing the vibration level, we can minimize noise pollution. Noise pollution can be controlled at three specific levels: (i) at the generation end, (ii) during the transmission path using innovative and absorbable barriers, by developing a green belt to attenuate the levels of sound, and (iii) by using protective devices like earplugs and earmuffs which can attenuate noise up to 32 dB.
