Some of the pollution control strategies to follow to reduce air pollution includes, Instead of driving, select to walk or ride a bike whenever possible. How can we control Noise Pollution. A one minute exposure to a sound level over IOOdBA can cause permanent hearing loss. For the purposes of these Rules, Trinidad and Tobago Noise Zones. The methods employed for noise control in buildings are explained in the following: 1. This paper addresses the problems of environmental noise pollution in Ilorin metropolis in particular and Nigerian urban areas in general with the implications of implementing its control measures on the sustainability of the urban areas. pollution level limits in 1970, noise pollution limits in 1971 and carbon dioxide and photochemical oxidant emissions limits in 1973. The massiveness of a material is an efficient parameter that resists noise.

It means the control of emissions and effluents into air, water or soil. Noise Pollution Control Rules Chap. We should not burst crackers. Noise can be defined as unwanted or undesired sound. (1) The Register shall be in the form determined by Register of the Authority. noise to study its impact on human beings and community as a whole. Noise level. Hence concrete walls are more insulating than wooden walls. 5.4. pressure, size of the lines and vessels etc. Acoustic, Sound and Noise Control. Browse through topics and tons of solved examples to practice solving easy and tough problems. 1 Assignment No.10A ECONOMICS OF POLLUTION CONTROL AJAY KUMAR School of Management Studies, University of Hyderabad The paper starts by understanding web of pollution and why it is necessary to control it. Noise is perhaps one of the most undesirable by products of modern mechanized lifestyle. One of the ways to lessen Air pollution is by using less fossil fuel. This book reviews the Bit by bit, we can contribute to a reduced noise surrounding. Section 2 (a) of the Air (Prevention and Control of Pollution) Act, 1981 states that noise is actually a part of air pollutant. GIS provide framework to integrate Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants.Pollution is often classed as point source or nonpoint source pollution. Noise Pollution: Sources, Effects and Control. ECONOMICS OF POLLUTION CONTROL. For sampling of noise levels from must be provided to reduce occupational exposure. Control measures: Policy measures; Modification of industrial process and selection of suitable fuels and its utilization. Fan noise is roughly proportional to the 5th power of fan speed. Hence, the present status of noise pollution in Ilorin metropolis poses a severe health risk to the residents. This is a major challenge in low and middle-income Pollution control is a term used in environmental management. The 1972 Noise Control Act—which was created to protect Americans from noise that poses a threat health and welfare—was terminated in 1982 due to a lack of federal funding. Typical noise level of 95-102 dB(A) (at operator position with no noise control cab) Not actual vehicle from study Solutions: Benefits: Costs: Noise control cab w/ air conditioning 82-90 dB(A) $12-15,000, 60-140 h Add sound suppression to existing cab 82-90 dB(A) $500-1000, 30-80 h The first step for new installations is to determine the noise criteria for sensitive locations Choose public transportation, instead of using own/commercial vehicles. We should use Loudspeakers at low volume and should not play music too loudly during parties. Noise Pollution. Design new machines to replace noisy ones. So in many cases it is possible to achieve a large noise reduction from a small drop in fan speed by changing control systems or pulley sizes and re-setting dampers. We can Reduce Noise pollution by turning off appliances when not in use, use of earplugs, lowering the volume, planting more trees, regular maintenance of vehicles and machines etc. Noise pollution simply means when there is a lot of noise in the environment which is consequentially harming the environment then it can be termed as noise pollution. Pollution being the most dangerous problem likes cancer in which death is sure but slow. Noise pollution can be hazardous to human health in the following ways: Hypertension: It is a direct result of noise pollution which is caused due to elevated blood levels for a longer duration. pollution prevention, they also address other environmental impact reduction techniques, such as recycling. It may not seem as insidious or harmful as the contamination of drinking water supplies from hazardous This is because the goal of NEPA is to identify any techniques (pollution prevention, recycling, or control) that will ultimately minimize environmental impacts. Engineering modifications, those changes that affect the source or the path of the sound, are the preferred methods of noise control in already established workplaces where noise protection was not factored in at the design stage. Noise pollution is the generation of sounds that are irritating and have a high pitch as compared to the hearing capabilities of humans. The following table provides a … Controlling at source This is only possible if working method is improved. The major sources of this pollution come from the motor vehicle engines, trains, aircraft, transportation systems, and systems. Sound intensity is measured in decibels (dB), that is the tenth part of the longest unit Bel. The complex and pervasive problem of noise pollution has no single solution; it requires a combination of short-, medium- and long-term approaches and careful consideration of the nature of the noise source. This fl uid borne noise can be attenuated by. Control of Noise Pollution Control at receivers end For people working in noisy areas ear protection aids like ear plugs, muffs, noise helmets, head phones etc should be provided it reduces occupational exposure. Noise pollution of urban areas is one of serious factors that the local agencies and state authorities have to consider in decision making processes.
