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.
Sensitivity of the human ear to sounds at different frequencies, measured by the A-weighted decibel scale with 0 dB Afor normal conversation has been put at between 45 dB A and 60 dB A when people are within three to six feet apart.
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.
