Noise is the main environmental pollution that causes stress. The noise is an unpleasant sound that has been increasing with the development of humanity, industry in general and urbanization. This is one of the pollutants of the environment that presents major problems for the health of man and animals.
Ambient noise caused by human activity has, due to its multiple effects on the human being and its environment, a great social, cultural and economic importance in today’s societies.
At present in audio has been main environmental pollution causing stress, in which the effects produced by the noise can be physiological like the hearing loss or the insomnia as also can be psychological like the irritability and the exageradmiento in the people of the Cities.
Sources of noise pollution to the environment
The main sources of environmental noise pollution are industrial equipment,construction, demolition, noise generated by human activity,such as lawn mowers or leaf blowers,loud music,barking dogs,children playing outdoors and Events such as concerts or festivals.
Other important sources of environmental noise pollution are those related to trransport: buses,trrains,cars,motorcycles, trucks and sirens or emergency vehicles,which are the most important cause of noise in urban areas
The effects noise pollution to the environment
In the environment the noise causes greater impact to the plants as the animals giving a harmful environmental impact in which we can have the following effects:
- Noise disturbs the feeding and breeding patterns of some animals and has been identifiled as a factor contributing to the extinction of some species.
- Noise has also been shown to have a detrimental effect on the reproduction of some plants
- Noise could also cause hearing loss
- Increase in workplace accidents in noisy environments due to decreased care
The characteristics of noise pollution
We have the following characteristics that only have noise pollution in the middle environment in which they are:
- It is a complex contamination of measuring and quantifying
- Do not move through natural systems, such as polluted air moved by the wind
- It has a much lower range of action than other pollutants
- Leaves no residue
- Does not have a comulative effect on the environmen
Sound pollution is called excess sound that alters normal ambient conditions in a given area. Although the noise does not accumulate, it moves or it maintains in the time like the other contaminations, also can cause great damages in the quality of life of the people if it is not controlled well or properly. The term “noise pollution” refers to noise (understood as excessive and annoying sound), caused by human activities (traffic, industries, entertainment, airplanes, etc.), which produces negative effects on the auditory, physical and of living beings.
Noise is defined as an unwanted sound, so it can be considered as inappropriate sound in the wrong place at the wrong time. Noise Pollution is any emission of a sound that may adversely affect the health or well-being of people, property or enjoyment thereof. Like all contaminants, it reduces the quality of life and produces a significant risk to health. In addition to the risks to human health, Noise Pollution has ecological impacts on sensitive species.
The noise of different means of transport constitutes a real annoyance that affects humans as it also affects animals and plants. How to reduce noise pollution.
Acoustic pollution is increasing rapidly and in some areas has been re-believed as a serious threat, noise pollution becomes a total tension to so many animals that also create many problems in prey-predator relationship. It also leads to a variety of breeding problems. Very serious noises can lead to problems for the habitats of some creatures that are sensitive to sound and as a result we have the depletion of rare species. Specifically those animals whose sense of hearing is u and acute as are whales and dolphins.
Effects of noise pollution are giving the negative impacts of so many on human health. Exposure to noise will lead to aggression, hearing loss, stress, sleep disorders and many more psychological problems. Researchers have shown that many people who can afford a new home have started buying houses in areas where noise disturbance is very low.
One of the main sources of noise pollution is our transport, especially noise caused by motor vehicles. Other sources include sirens of emergency services, alarms, factory machinery, office equipment, construction work, power tools, barking dogs, loudspeakers, different audio systems, stage lighting and buzzing disturbance meetings can cause noise pollution. Among all these motor vehicles are the main sources of noise pollution.
Other important sources of environmental noise pollution are those related to transport: buses, trains, cars, motorcycles, trucks and sirens or emergency vehicles, which are the most important cause of noise in urban areas.
The acoustic pollution for the environment has been bringing along with it a greater impact to the plants as the animals the same ones that give a detrimental environmental impact in which it has a variety of effects like for example we have disturbs the patterns of feeding and reproduction Has been identified as contributing to the extinction of some species, noise has also been shown to have a detrimental effect on the increase in work-related accidents in noisy environments due to Reproduction of some plants, noise could also cause hearing loss. The characteristics of the noise pollution in the environment in which it is are the following is a complex contamination of measurement and quantification, do not move through natural systems, such as polluted air moved by the wind, has a range of action Much lower than other pollutants, leaves no residue, has no cumulative effect on the environment.
Acoustic pollution is a problem with health effects that could become serious as it also has health effects of noise pollution are not only related to hearing damage but also cause other effects on the body that are not easily attributable to noise. Noise is an evil of our times. Perhaps it is a type of pollution that not only affects the environment, but directly affects the health of the man. The noise pollution, or acoustic, can happen of being an annoying noise, to become a source of real psychological problems or of physical pains caused by sounds that reach 140 decibels, the pain threshold.
Noise acts on the nervous system through the ear organ. When noise exceeds certain levels, deafness and pathological effects occur. At much lower levels, noise produces discomfort and hinders or impedes attention, communication, concentration, rest and sleep. The reiteration of these situations can cause chronic states of nervousness and stress which, in turn, leads to psychophysical disorders, cardiovascular diseases and alterations of the immune system. (Murillo, 2015).
Acoustic pollution caused by humans affected some animals. Scientists have shown that it also has an effect on plants, indirect but real. In this case, noise can favor pollination but reduces the dispersion of certain seeds. It is clear that plants have no ears. However, it is quite possible that they are affected by acoustic contamination of human origin. Obviously, not directly, (Octavio, 2012)
Today there is a great variety of recommendations that will serve as an aid to reduce noise pollution and thus do not damage drastically to living things to which the noise does not help them at all.
Noise is a nuisance for many living things but there are different recommendations to reduce noise pollution such as not practicing noisy behavior at home such as screaming, heels, use of appliances in periods of rest, lower the volume of equipment Of music making sure that you only hear at home, in the car do not use the horn except in situations of imminent danger, at the same time do not allow pets to affect or damage the right of people to rest and tranquility.
Acoustic pollution is excessive noise caused by different factors such as the use of means of transport and the use of noisy instruments which affect the health of humans, plants and animals. Acoustic pollution in some cases has been bringing serious consequences as one of them is the extinction of animals or plants that are sensitive to noise.
Noise is one more way to pollute the environment as it is a nuisance to have to hear an unpleasant noise the same that affects humans, plants, and animals. It would be very feasible to follow some of the recommendations to gradually reduce noise pollution.
