The Clean Air Act Amendments added a new title IV, relating to acid deposition control, without repealing the existing title IV, relating to noise pollution.

Exposure to prolonged or excessive noise has been shown to cause a range of health problems ranging from stress, poor concentration, productivity losses in the workplace, and communication difficulties and fatigue from lack of sleep, to more serious issues such as cardiovascular disease, cognitive impairment, tinnitus and hearing loss.

As the world becomes more urbanized, the use of machine-technology increases, and levels of development become higher and more complex, human exposure to noise increases. One authority estimates that the average noise level in the American city is increasing by 1 dB annually. Despite the importance and great scale of the problem, geographers generally have ignored the field of noise pollution research, perhaps because specialized equipment is necessary to accumulate the data required for analysis. As a result, most noise pollution research has been performed by traffic engineers, industrial designers and urban planners to solve immediate problems with little regard for more general consideration.

What are the health effects of noise pollution?

Noise pollution occurs when unwanted sounds enter the environment. The potential health effects of noise pollution include increased stress levels, sleep disturbance, or hearing damage. Some examples of noise pollution sources include :. This article looks at noise pollution in more detail and its potential health effects. We will also discuss ways to reduce noise pollution.

Noise pollution is an invisible danger. It cannot be seen, but it is present nonetheless, both on land and under the sea. Noise pollution is considered to be any unwanted or disturbing sound that affects the health and well-being of humans and other organisms. Sound is measured in decibel s.

Noise health effects are the physical and psychological health consequences of regular exposure to consistent elevated sound levels. Noise from traffic, in particular, is considered by the World Health Organization to be one of the worst environmental stressors for humans, second only to air pollution. Although age-related health effects presbycusis occur naturally with age, [5] in many countries the cumulative impact of noise is sufficient to impair the hearing of a large fraction of the population over the course of a lifetime. Adverse cardiovascular effects occur from chronic exposure to noise due to the sympathetic nervous system's inability to habituate. The sympathetic nervous system maintains lighter stages of sleep when the body is exposed to noise, which does not allow blood pressure to follow the normal rise and fall cycle of an undisturbed circadian rhythm. Stress from time spent around elevated noise levels has been linked with increased workplace accident rates and aggression and other anti-social behaviors.

NOISE POLLUTION

Background: Tens of millions of Americans suffer from a range of adverse health outcomes due to noise exposure, including heart disease and hearing loss. Reducing environmental noise pollution is achievable and consistent with national prevention goals, yet there is no national plan to reduce environmental noise pollution. Objectives: We aimed to describe some of the most serious health effects associated with noise, summarize exposures from several highly prevalent noise sources based on published estimates as well as extrapolations made using these estimates, and lay out proven mechanisms and strategies to reduce noise by incorporating scientific insight and technological innovations into existing public health infrastructure. Tens of millions more may be at risk of heart disease, and other noise-related health effects. Direct regulation, altering the informational environment, and altering the built environment are the least costly, most logistically feasible, and most effective noise reduction interventions. Conclusion: Significant public health benefit can be achieved by integrating interventions that reduce environmental noise levels and exposures into the federal public health agenda. Environmental noise pollution in the United States: developing an effective public health response.

Health effects of environmental noise pollution

Atmospheric pollution is not the only type of contamination that is harming living beings on the planet. And according to the European Environment Agency EEA , noise is responsible for 16, premature deaths and more than 72, hospitalisations every year in Europe alone. According to the WHO, noise is harmful when it exceeds 75 decibels dB and feels painful at levels above dB.

Most of us are accustomed to the sounds we hear every day. However, when the sound of the television keeps you from sleeping all night or the traffic starts giving you a headache, it transcends the boundaries of mere noise and qualifies as noise pollution. However, the noise that tends to disrupt the natural rhythm of life makes for one of the biggest pollutants. By definition, noise pollution takes place when there is either an excessive amount of noise or an unpleasant sound that causes a temporary disruption in the natural balance.

Noise pollution , unwanted or excessive sound that can have deleterious effects on human health, wildlife, and environmental quality. Noise pollution is commonly generated inside many industrial facilities and some other workplaces, but it also comes from highway, railway, and airplane traffic and from outdoor construction activities. Sound waves are vibrations of air molecules carried from a noise source to the ear. Sound is typically described in terms of the loudness amplitude and the pitch frequency of the wave. Loudness also called sound pressure level, or SPL is measured in logarithmic units called decibels dB.

Но Танкадо… - размышляла.  - С какой стати такой параноик, как Танкадо, доверился столь ненадежному типу, как Хейл. Сьюзан понимала, что теперь это не имеет никакого значения.

 Turista, - усмехнулся. И прошептал чуть насмешливо: - Llamo un medico. Вызвать доктора. Беккер поднял глаза на усыпанное родинками старческое лицо. - No, gracias.

Он подбежал к крепко сбитому охраннику. - Мне срочно нужно такси. Охранник покачал головой. - Demasiado temperano. Слишком рано.

Environmental Noise Pollution in the United States: Developing an Effective Public Health Response

Introduction

 Иного рода? - Сьюзан смотрела на него вопрошающе. Невзламываемый шифр - математическая бессмыслица. Он это отлично знает. Стратмор провел рукой по вспотевшему лбу. - Этот шифр есть продукт нового типа шифровального алгоритма, с таким нам еще не приходилось сталкиваться. Эти слова повергли Сьюзан в еще большее смятение.

Беккер закрыл глаза, стиснул зубы и подтянулся. Камень рвал кожу на запястьях. Шаги быстро приближались. Беккер еще сильнее вцепился во внутреннюю часть проема и оттолкнулся ногами. Тело налилось свинцовой тяжестью, словно кто-то изо всех сил тянул его. Беккер, стараясь преодолеть эту тяжесть, приподнялся на локтях.

Долгая пауза. - Сэр… я не нахожу Клауса Шмидта в книге заказов, но, быть может, ваш брат хотел сохранить инкогнито, - наверное, дома его ждет жена? - Он непристойно захохотал. - Да, Клаус женат. Но он очень толстый. Жена отказывает ему… ну, вы понимаете.

 Буисан, - сказал Беккер.  - Мигель Буисан.

Фонтейн заставил Мидж и Бринкерхоффа стоять, пока сам он молча совершал свой обычный ритуал заваривания кофе сорта Гватемальская ява. Затем он сел за письменный стол и начал их допрашивать, как школьников, вызванных в кабинет директора, а они по-прежнему стояли. Говорила Мидж - излагая серию необычайных событий, которые заставили их нарушить неприкосновенность кабинета. - Вирус? - холодно переспросил директор.  - Вы оба думаете, что в нашем компьютере вирус.

Noise pollution can cause headaches, high blood pressure, respiratory agitation, racing pulse, and, in exposure to extremely loud, constant noise, gastritis, colitis.
