Steps that can be taken to control noise pollution include erecting barriers to insulate noise producers, installing materials that absorb sound, dissipating noise-generating vibrations and placing physical breaks between a vibrating object and the hearer. Architectural acoustics use all of these techniques to protect residents from unwanted sound. In addition, roads and airports require special treatment to deaden noise pollution.Continue Reading
As eSchoolToday points out, tested methods for protecting neighborhoods from noise pollution include creating barriers by placing noisy machinery in soundproofed rooms or planting trees along roadways. Urban planning plays a key role in placing noisy industries, airports and major transportation hubs away from residential areas, as well as in regulating smaller sources of noise pollution such as public announcement systems, car horns and noisy vehicles.
Noise pollution from roads can be mitigated through careful design of the road, the materials used, better tire tread design and the erection of road barriers to limit road noise to the roadway itself. In addition, electric and hybrid cars help minimize road noise pollution.
The best ways to control noise pollution from airports focus on building airports away from residential districts, restricting flights to certain hours and redesigning flight paths. In addition, residential soundproofing can help control noise pollution for those living near an airport.Learn more about Human Impact
Wetlands face destruction due to threats such as commercial development, industry, urbanization, agriculture, invasive species, pollution, climate change and dams. It is estimated that approximately half of the world's wetlands have disappeared since 1900. The loss or alteration of wetlands is believed to contribute to global warming.Full Answer >
Wastewater management is a field concerned with both the treatment of wastewater from municipal and industrial sources as well as the management of water to prevent overuse and pollution. The wastewater discharged by municipal sewers and industrial operations often contains pollutants that could have a major effect on wildlife and the water table, which makes treating this output before returning it to the water cycle is important.Full Answer >
The use of biomass to create energy offers producers the chance to stop using fossil fuels; the extraction process for fossil fuels often affects the environment adversely, as does the pollution that comes from the consumption of those fossil fuels. Biomass could eliminate those pollutants from the earth's atmosphere.Full Answer >
According to environmental lawyer Diane Saxe, factories that wish to reduce emissions can practice either pollution prevention or pollution control. Pollution prevention means changing the way a factory operates so that it produces very little or none of a particular pollutant. This usually involves eliminating a certain chemical or material from its operations. Pollution control involves installing equipment that captures pollutants before they enter the environment.Full Answer >
