Fong's research methodology was modeled after Schafer, and the essay writing noise pollution research findings show how not only do soundscapes differ, but they also rather explicitly point to the level of urban development in the area; that is, cities in the periphery - in Immanuel Wallerstein-speak - will. Fong's important findings tie not only soundscape appreciation to our subjective views of sound, but also demonstrates how different sounds of the soundscape are indicative of class differences in urban environments.13 Wildlife edit Noise can have a detrimental effect on wild animals, increasing the risk of death by changing the delicate balance in predator or prey detection and avoidance, and interfering the use of the sounds in communication, especially in relation to reproduction and. Acoustic overexposure can lead to temporary or permanent loss of hearing. An impact of noise on wild animal life is the reduction of usable habitat that noisy areas may cause, which in the case of endangered species may be part of the path to extinction.Noise pollution may have caused the death of certain species of whales that beached themselves after being exposed to the loud sound of military sonar. 14 (see also Marine mammals and sonar ) Noise also makes species communicate more loudly, which is called Lombard vocal response. 15 Scientists and researchers have conducted experiments that show whales' song length is longer when submarine-detectors are. 16 If creatures do not "speak" loudly enough, their voice will be masked by anthropogenic sounds.
Less addressed is how humans adapt to noise subjectively. Indeed, tolerance for noise is frequently independent of decibel levels.However, Murray Schafer's soundscape research was groundbreaking in this regard. In his eponymous work, he makes compelling arguments about how humans relate to noise on a subjective level, and how such subjectivity is conditioned by culture.12 He also notes that sound is an expression of power, and as such, material culture (e.g., fast cars or Harley Davidson motorcycles with write a police report ks2 aftermarket pipes) tend to have louder engines not only for safety reasons, but for expressions pay to do my essay of power by dominating the soundscape. Other key research in this area can be seen in Fong's comparative analysis of soundscape differences between Bangkok, Thailand and Los Angeles, California,.
High noise levels can contribute to cardiovascular effects in humans and an increased incidence of coronary artery disease. 4, 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. 5, contents, humans edit, main article: Health effects from noise. Noise pollution affects both health and behavior.Unwanted sound (noise) can damage psychological health. Noise pollution can cause hypertension, high stress levels, tinnitus, hearing loss, sleep buy writing paper london disturbances, and other harmful effects. 6 7 8 9, reaction to noise Sound becomes unwanted when it either interferes with normal activities such as sleeping, conversation, or disrupts or diminishes one's quality of life.10 Chronic exposure to noise may cause noise-induced hearing loss. Older males exposed to significant occupational noise demonstrate more significantly reduced hearing sensitivity than their non-exposed peers, though differences in hearing sensitivity decrease with time and the two groups are indistinguishable by age.11 A comparison of Maaban tribesmen, who were insignificantly exposed to transportation or industrial noise, to a typical.S. Population showed that chronic exposure to moderately high levels of environmental noise contributes to hearing loss. 6 High noise levels can result in cardiovascular effects and exposure to moderately high levels during a single eight-hour period causes a statistical rise in blood pressure of five to ten points and an increase in stress, 6 and vasoconstriction leading to the increased blood.
Traffic is the main source of noise pollution in cities. Noise pollution or noise disturbance 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 by machines 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. Documented a research paper outline problems associated with urban noise go back as far as Ancient Rome.3, outdoor noise can be caused by machines, construction activities, and music performances, especially in some workplaces. Noise-induced hearing loss can be caused by outside (e.g. Trains) or inside (e.g.
