Noise pollution is harmful to human health-Noise pollution or any noise that limits the hearing of an animal can cause sound effects. Traffic jams, loud noises from factories, and pollutant movements are applied. Humans generally cannot hear sounds below or above 20,000-20,000 Hz.
Noise pollution refers to excessive, unpleasant, or harmful environmental noise levels that negatively impact human health and well-being. It is a growing problem in many urban and suburban areas, and its sources can range from transportation, industrial activities, construction, and even household appliances.
Noise-control laws and laws laid down at the exotic, local, and civil degrees can be effective in allaying the adverse belongings of noise pollution. Environmental and mechanical noise is regulated in the United States under the Occupational Safety and Health Act of 1970 and the Noise Control Act of 1972. Under these acts, the Occupational Safety and Health Administration set up mechanical noise criteria to deliver limits on the intensity of sound exposure and on the time duration for which that intensity may be allowed.
The adverse effect of noise on the daily activities of humans and animals is known as noise pollution. Noise pollution is mainly caused by machinery, transport, and management deficiencies. Poor urban planning increases noise pollution, while industrial buildings can cause noise pollution in residential areas. The main noise sources in residential areas include loud music, transport, rail, aircraft, etc., construction work, electrical generators, and people noise.
Any sound that exceeds the range of human or animal hearing is likely to cause hearing damage. Traffic jams and factories emit loud noises that cause pollution. Humans generally cannot hear sounds below or above 20,000-20,000 Hz. So noise pollution for humans is caused by louder sounds within this range. Noise is primarily measured in decibels (dB).
According to the study, the average noise level in residential areas is 97 decibels, which is much higher than the World Health Organization’s approved average noise level of 50 decibels. High noise levels contribute to cardiovascular disease and coronary artery disease in humans. In animals, noise pollution can increase the risk of death, affect reproduction and navigation, and cause permanent hearing damage.
The human ear is sensitive enough to any sound. Therefore, loud sounds hit the eardrum quite hard, which can also damage the eardrum. Its harmful effects on children can be far-reaching. Due to the greater variation in sound in childhood, they have various ear problems in old age. Noise pollution is harmful to human health-The group investigated the causes of noise pollution in different regions and it was found that in those regions where the level of pollution is high, the following disadvantages or harmful effects on people:
(a) Irritability of people in pollution-affected areas,
(b) Abnormalities in behavior and emotional tension,
(c) Making people tired, lethargic, and inattentive,
(d) Memory loss in elderly people and
(e) There are even reports of deafness.
In addition to hearing loss, noise pollution causes problems in both human health and behavior. The physical and mental normal functioning of a person can be greatly significantly due to unnecessary and excessive noise. Noise pollution can cause anxiety, agitation, high blood pressure, hearing loss, sleep disturbance, and other harmful and adverse reactions. Also, other different reactions can be memory loss, mental fatigue, etc.
Noise can cause cardiac problems in the elderly. According to the World Health Organization, children are particularly vulnerable and the effects of noise pollution on children can be permanent. Noise poses a serious threat to a child’s physical and mental health and hurts a child’s learning and behavior. Noise pollution affects both health and behavior.
Prolonged exposure to sound levels above 85 decibels can cause hearing loss. Exposure to noise at work can cause hearing loss and other health problems.
Roadways and other urban noise pollution factors can be reduced by better urban planning and road design. Roadway noise can be reduced by vehicle speed restrictions, surface texture changes, heavy vehicle restrictions, advanced traffic control technology to reduce braking, and tire design. An important application of these techniques is a computer model for roadway noise control.
Which is capable of local topography, weather, traffic operations, and hypothetical mitigation. Aircraft noise can be reduced by using silent jet engines. Residents near airports can also be protected from noise pollution by changing flight paths and runway timings.
Governments and organizations have taken steps to reduce noise pollution through regulations and education campaigns.Noise pollution is harmful to human health- For example, many cities have introduced noise barriers, enforced quiet hours, and implemented noise limits for construction sites and transportation.
Noise pollution is a serious issue that affects both human health and the environment. Individuals, communities, and governments need to work together to reduce noise levels and create a quieter and healthier world.
