Noise pollution has many adverse affects on humans, including stress-related illnesses, hearing loss, sleep disruption, speech interference and loss of productivity, according to eSchoolToday. Perhaps the most acute problem associated with noise pollution is the hearing loss it can cause after long-term exposure. Affecting the eardrums, noise pollution can cause permanent damage when present for a prolonged period of time.
Other reactions to noise pollution manifest in anxiety and stress-related reactions that include extreme fright. Noise pollution can lead to headaches, nervousness, irritability, fatigue and decreased efficiency at work.
Because noise pollution can produce harmful effects, local and state government take numerous steps to limit and prevent excessive noise pollution. Enforcement of laws regarding public speaker announcements, parties and loudspeakers cut down on a lot of noise; however, necessary facilities such as airports, bus and transport terminals do contribute heavily to noise pollution as well. For this reason, these facilities are typically situated away from residential areas.
Vegetation such as trees and bushes planted along property borders can provide a sound barrier, as these all absorb sound. In addition, embankments and walls can also deflect excessive sound. Many community laws require silence near certain areas including schools, colleges and hospitals.
