Scope and limitation for noise pollution

For instance, urbanization has been associated with the precarious rise in energy consumption and global climate change [ 79101112 ], degrading urban ecology [ 13141516171819 ], urban land degradation and increased disaster rate [ 202122232425 ], profound cultural change and infiltration [ 262728 ], as well as extreme generation of hazardous waste [ 29303132 ], among others.

Their main project was to do first-hand research about the sounds in nature and how those sounds are affected by noise pollution from helicopter tours and other man-made distractions. Table 1 A-weighted noise level standards in selected countries of the world [ 65 ]. Nathaniel Mead More than 15 million Americans currently have some form of coronary heart disease CODwhich involves a narrowing of the small blood vessels that supply blood and oxygen to the heart.

She also participated in the trip as the expedition leader. Environmental noise pollution, a form of air pollution, is a threat to health and well-being. The problem forms a special type of air pollution. Full scholarships were given to many of the participants, according to Portal.

Scope of air pollution control

Because many animals also eliminate plants or eat or disperse their seed, , certain studies were conducted and researcher found out that because plants cannot move they just rely on birds and other animals, those animals that were affected by noise pollutants derive the effect to plants and these results to plants to pollinate slowly or even die. Table 1 A-weighted noise level standards in selected countries of the world [ 65 ]. In most cases, the sources of pollution are direct or otherwise by-products of the quickly increasing and divergent, environment-destroying activities of man. Sensitivity of the human ear to sounds at different frequencies, measured by the A-weighted decibel scale with 0 dB A , for normal conversation has been put at between 45 dB A and 60 dB A when people are within three to six feet apart. MM Sound comes from the vibrations in molecules, and is always traveling through a substance, whether it is a solid, liquid, or gas. Noise pollution or environmental noise is displeasing human-, animal- or machine-created sound that disrupts the activity or balance of human or animal life. Many urgent research needs are also identified.

While some forms of pollution, such as water [ 353637 ], air [ 38394041 ], land [ 2242 ], and soil pollution [ 24434445 ] are more obvious and have generated a great deal of research interest across the globe, and especially in developing countries, noise, as a major pollution in contemporary urban settlements of developing countries, has not been given necessary attention.

But since noise pollution is an intangible dilemma, unlike other societal problems like garbage, the enforcement is questionable.

This study characterized noise pollution levels in Ibadan and Ile-Ife, two urban areas of Southwestern Nigeria that have experienced significant increases in population and land use activities.
