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. There are approximately 10, deaths per year as a result of noise in the European Union.

What Is Noise Pollution?

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. Descriptive statistics were performed, and analysis of variance was also conducted using Minitab version

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.

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.

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.

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.
