Noise pollution
introduction
Noise pollution is the disturbing or excessive noise that may harm the activity or balance of human or animal life. The source of most outdoor noise worldwide is mainly caused bymachines and transportation systems, motor vehicles, aircraft, and trains.[1][2] Outdoor noise is summarized by the word environmental noise. Poor urban planning may give rise to noise pollution, since side-by-side industrial and residential buildings can result in noise pollution in the residential areas.
Indoor noise is caused by machines, building activities, music performances, and especially in some workplaces. There is no great difference whether noise-induced hearing loss is brought about by outside (e.g. trains) or inside (e.g. music) noise.
High noise levels can contribute to cardiovascular effects in humans, a rise in blood pressure, and an increase in stress and vasoconstriction, and an increased incidence of coronary artery disease. In animals, noise can increase the risk of death by altering predator or prey detection and avoidance, interfere with reproduction and navigation, and contribute to permanent hearing loss.
It is extremely important that we understand how sound pollution affects us. Some of us may be suffering from the negative effects of sound pollution and not know it because they dismiss it assomething trival when it is actually not. Therefore this page will be dedicated to explaining exactly what noise pollution is about, what causes it, how to calculate sound and how fast it travels.
Effects
Human[edit]
Noise pollution affects both health and behavior. Unwanted sound (noise) can damage psychological health. Noise pollution can cause trouble, hypertension, high stress levels,tinnitus, hearing loss, sleep disturbances, and other harmful effects.[3][4][5][6] Furthermore, stress and hypertension are the leading causes to health problems.[4][7]
Sound becomes unwanted when it either interferes with normal activities such as sleeping,
