What is 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. Drivers honking the horn, groups of workers drilling the road surface, aircraft flying over us in the sky Noise, noise and more noise. Cities have become the epicentre of a type of pollution, acoustics, which, although its invisibility and the fact that coronavirus crisis reduced it until almost yearn it, is severely damaging to human beings.
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. This definition is usually applicable to sounds or noises that are unnatural in either their volume or their production. Our environment is such that it has become difficult to escape the noise. Even electrical appliances at home have a constant hum or beeping sound.
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,  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.
According to the World Health Organization, sound levels less than 70 dB are not damaging to living organisms, regardless of how long or consistent the exposure is. Exposure for more than 8 hours to constant noise beyond 85 dB may be hazardous. If you work for 8 hours daily in close proximity to a busy road or highway, you are very likely exposed to traffic noise pollution around 85dB. Whether we realize we are subjected to it or not, noise pollution can be hazardous to our health in various ways. Our oceans are no longer quiet. Thousands of oil drills, sonars, seismic survey devices, coastal recreational watercraft and shipping vessels are now populating our waters, and that is a serious cause of noise pollution for marine life. Whales are among the most affected, as their hearing helps them orient themselves, feed and communicate.

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. This study collated data from various large-scale epidemiological studies of environmental noise in Western Europe, collected over a year period. The studies analysed environmental noise from planes, trains and vehicles, as well as other city sources, and then looked at links to health conditions such as cardiovascular disease, sleep disturbance, tinnitus, cognitive impairment in children, and annoyance. Their results might surprise you. They found that at least one million healthy years of life are lost each year in Europe alone due to noise pollution and this figure does not include noise from industrial workplaces.
Noise pollution has become a major environmental problem leading to nuisances and health issues. This paper aims to study and analyse the noise pollution levels in major areas in Ota metropolis. A probability model which is capable of predicting the noise pollution level is also determined. Datasets on the noise pollution level in 41 locations across Ota metropolis were used in this research. The datasets were collected thrice per day; morning, afternoon and evening.

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.
Faisalabad is one of the major industrial cities of Pakistan, which may cause noise pollution to the local residents due to the development of robust industrial and transport systems. This study aimed at i mapping the noise pollution levels at various locations of Faisalabad city; ii comparing noise pollution levels in the morning, the afternoon, and the evening for each source; and iii assessing nonauditory effects of noise on human health. A questionnaire-based survey was carried out near the sampling points to get a public perception about the health impacts of noise pollution. The measured equivalent sound pressure levels SPLeq were higher than the permissible limits at all the sampling locations during morning, afternoon, and evening hours.
Health effects from noise
Мы организуем утечку секретной информации. И весь мир сразу же узнает о ТРАНСТЕКСТЕ. Сьюзан вопросительно смотрела на. - Это совсем просто, Сьюзан, мы позволим правде выйти за эти стены.
Невзламываемый шифр. Но это полный абсурд. Неужели Хейл никогда не слышал о принципе Бергофского.
Все системы должны заработать через пять минут. Грег Хейл убил одного из младших сотрудников лаборатории систем безопасности и взял в заложники моего старшего криптографа. Если нужно, используйте против всех нас слезоточивый газ. Если мистер Хейл не образумится, снайперы должны быть готовы стрелять на поражение. Всю ответственность я беру на. Быстрее. Хейл выслушал все это, не сдвинувшись с места и не веря своим ушам.

Noise pollution: how to reduce the impact of an invisible threat?
Все вокруг светилось ярко-красными огнями. Шифровалка умирала. То же самое будет и со мной, - подумала. Сьюзан вспомнила о единственном остающемся выходе - личном лифте Стратмора. Но она понимала, что надежды нет: электроника вряд ли уцелела после катастрофы. Двигаясь в дыму, она вдруг вспомнила слова Хейла: У этого лифта автономное электропитание, идущее из главного здания.
В понедельник я проверю твою машину.
Крошечная сноска гласила: Предел ошибки составляет 12. Разные лаборатории приводят разные цифры. ГЛАВА 127 Собравшиеся на подиуме тотчас замолчали, словно наблюдая за солнечным затмением или извержением вулкана - событиями, над которыми у них не было ни малейшей власти. Время, казалось, замедлило свой бег. - Мы терпим бедствие! - крикнул техник.
Спасибо. - Он улыбнулся и сразу перешел к делу.
Но это была не кровь. Что-то другое. Предмет материализовался как бы ниоткуда, он вылетел из кабинки и ударил убийцу в грудь, из-за чего тот выстрелил раньше времени. Это была сумка Меган.
