Noise pollution

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.

In the cities, the level of noise pollution in residential areas can be greatly increased due to improper urban planning other important sources of noise pollution in urban areas are industrial enterprises, construction and repair work, car alarms, dogs barking.

Noise pollution effects both health and behavior. Unwanted sound

can damage psychological health. Noise pollution can cause

hypertension, high stress levels, tinnitus, hearing loss, sleep

disturbances, and other harmful effects.

Sound becomes unwanted when it either interferes with

normal activities such as sleeping, conversation, or

disrupts or diminishes one’s quality of life

High noise levels can contribute to 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, and vasoconstriction leading to the increased blood pressure noted above, as well as to increased incidence of coronary artery disease

WildlifeNoise pollution quickly causes a disturbance of the natural balance in ecosystems. Noise pollution can lead to a violation of orientation in space, communication, foraging, and so on.. In this regard, some animals begin to publish more loud noises, because of what they will become in the role of secondary pollutants sound, even more disturbing equilibrium ecosystem

One of the most famous cases of damage caused by noise pollution nature are numerous instances where dolphins and whales are beaching themselves, losing orientation due to the loud sounds of military sonar

Noise reduction and controlNoise pollution from any object can be somewhat reduced if in the drafting of this object to model, taking into account different environmental conditions, the nature of the noise that will occur, and then find ways to eliminate or at least reduce it. Currently, this method has become much easier and more affordable due to the development of computer technology. This is the most cheap and efficient way to reduce the noise, which is used, for example, in the construction of railways in urban areas
