Noise pollution

1. Noise pollution

2. 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.

3. 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.

4. 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

5. 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

6. Wildlife
Noise 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

7. 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

8. Noise 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
