2. Noise pollution is a type of
energy pollution in which
distracting, irritating, or
damaging sounds are freely
audible.
3. In this type of contamination the humans are
the main guilty because is due to them who
exist noise harmful to health or welfare.
Transportation vehicles are the worst
offenders, with aircraft, railroad stock, trucks,
buses, automobiles, and motorcycles all
producing excessive noise.
4. In the narrowest sense, sounds are considered
noise pollution if they adversely affect wildlife,
human activity, or are capable of damaging
physical structures on a regular, repeating basis.
5. Noise pollution can cause
annoyance and aggression,
hypertension, high stress
levels, tinnitus, hearing
loss, sleep disturbances,
and other harmful effects.
6. An impact of noise
on animal life is the
reduction of usable
habitat that noisy
areas may cause,
which in the case of
endangered species
may be part of the
path to extinction.
7. Train, airplane automobile,
motorcycle, and even
entertainment noise can disturb
wildlife habits, sleep disruption in
humans and animals, hearing
loss, heart disease and in severe
cases even mental instability.
8. There are a variety of strategies for mitigating
roadway noise including: use of noise barriers,
limitation of vehicle speeds, alteration of roadway
surface texture, limitation of heavy vehicles, use of
traffic controls that smooth vehicle flow to reduce
braking and acceleration, and tire design.
9. Aircraft noise can be
reduced to some
extent by design of
quieter jet engines,
which was pursued
in the 1970s and
1980s.
10. Another solution to this problem is to use
electric, or hybrid-electric, automobile. Hybrid
vehicles are so quite
11. Many conflicts over noise pollution
are handled by negotiation
between the emitter and the
receiver.
12. Noise pollution often persists because
only five to ten percent of people affected
by noise will lodge a formal complaint.
13. Many people are not aware of their legal right to
quiet and do not know how to register a complaint.
