Harmful Effects of Noise Pollution
Noise is the unpleasant and undesirable sound that leads to discomfort in human beings and wildlife, also known as environmental noise or sound pollution. The source of outdoor noise is mainly caused by transport, industrial machines, loudspeakers, etc. Poor urban planning may give rise to noise disintegration or pollution, side-by-side industrial and residential buildings can result in noise pollution in the residential areas. Some of the main sources of noise in residential areas include loud music, traffic, rail, airplanes, lawn care maintenance, construction, wind turbines, generator explosions, and people.
High noise levels can contribute to cardiovascular effects, stress, hearing impairment in humans and wildlife, and an increased incidence of coronary artery disease. In wildlife, noise can increase the risk of death by prey detection and avoidance, reproduction, and navigation, and contribute to permanent hearing loss. Noise pollution is a major concern in the ocean. In the past few years, scientists have shifted to conducting studies on invertebrates and their responses to anthropogenic sounds in the marine environment. This research is essential, especially considering that invertebrates make up a maximum of marine species, and thus compose a large percentage of ocean food webs. A variation in the complexity of their sensory systems exists, which allows scientists to study a range of characteristics and develop a better understanding of noise impacts on living organisms.
Effects of Noise Pollution on Human Health and Wildlife
Noise barrier has several effects in day to day life and they are:
- Hearing loss: Constant exposure to loud music to human ears that are beyond the range of sound that human ears can withstand damages the eardrums, resulting in loss of hearing.
- Hypertension: It is a direct result of noise pollution which is caused due to elevated blood levels for a longer duration.
- Sleeping disorders: Lack of sleep might result in fatigue and low energy level throughout the day affecting everyday activities. Noise pollution hampers the sleep cycles leading to irritation and an uncomfortable state of mind.
- Cardiovascular issues: Heart-related problems such as blood pressure level, stress and cardiovascular diseases might come up in a normal person and a person suffering from any of these diseases might feel a sudden shoot up in the level.
- Reproduction issues: majorly in wildlife, the reproduction rate is falling due to an increase in noise pollution.
Prevention of Noise Pollution
- Honking in public places like teaching institutes, forests, hospitals, etc. should be banned by the authorities.
- Installation of Delnoise systems in forest and city areas.
- In commercial, hospital, and industrial buildings, adequate soundproof systems should be installed.
- Loudspeakers, sound instruments should be controlled to desirable limits.
- A dense tree shall be encouraged by the authorities to
- Explosives are to be restricted in forest, mountainous and mining areas.
