Noise is a prominent feature of the environment including that from sources such as transport, industry and neighborhood. Noise pollution is becoming more and more acute, and hence many researchers are studying the effect of noise pollution on people and its attenuation. Sound that is unwanted or disrupts one’s quality of life is called as noise. When there is a lot of noise in the environment beyond certain limit, it is termed as noise pollution. Sound becomes undesirable when it disturbs the normal activities such as working, sleeping, and during conversations. It is an underrated environmental problem because of the fact that it can’t be seen, smelt, or tasted. Noise is normally defined as 'unwanted sound'. A more precise definition could be: noise is audible sound that causes disturbance, impairment or health damage. The terms 'noise' and 'sound' are often synonymously used when purely acoustical dimension is meant (e.g., noise level, noise indicator, noise regulation, noise limit, noise standard, noise action plan, aircraft noise, road traffic noise, occupational noise, etc.). The link between exposure and outcome (other terms: endpoint, reaction, response) is given by reasonably well-established exposure-response. Managing noise is crucial for enhancing the living condition of a dwelling. Noise can be generated internally within a building (e.g., noise from surrounding neighbors’ voices, music or appliances) or externally (e.g., traffic noise from automobiles, buses, trains, aircraft, industrial activities or surrounding construction activities). Noises (or impact of sounds) are transmitted through building materials from sound sources such as vehicular or foot traffic, banging, or objects being dropped to the floor and can also be associated with vibrations.
Sources of Noise Pollution
The primary objective of noise control is to quantify the exceedance of noise level above permissible level at selected types of sources, identify appropriate and innovative noise barrier designed to attenuate noise level that has potential for implementation at the sources of selected types in which the noise levels are high when compared to the standards. Based on the study and evaluation to be conducted for site; the recommendation for noise control should be suggested and it may be acoustic enclosure and thick three tier green belt and ornamental plantation.
We at BCPL, provide the recommendation as per study for noise generation, sources and machinery in use for best suited method to control noise at site and in work place.
