Noise pollution is excessive, unpleasant noise that disrupts human or animal activity or health. It is a form of energy pollution caused by distracting or irritating sounds. Noise is measured in decibels and can damage hearing and increase health risks. It harms animals by interfering with communication, navigation, and increasing mortality. Noise pollution also negatively impacts plants' growth and can even cause death. Efforts should be made to reduce sources of noise through community planning, public education, limiting domestic and vehicle noise, and using noise-reducing technology.

2. A SOUND, ESPECIALLY
ONE THAT IS LOUD OR
UNPLEASANT OR THAT
CAUSES DISTURBANCE IS
CALLED A NOISE.

3. What is Noise Pollution?
Noise pollution is excessive,
displeasing human, animal, or
machine-created environmental
noise that disrupts the activity or
balance of human or animal life.
The word noise may be from the
Latin word nauseas, which means
disgust or discomfort.

4. IT IS A TYPE OF
ENERGY POLLUTION IN
WHICH DISTRACTING,
IRRITATING, OR
DAMAGING SOUNDS ARE
FREELY AUDIBLE.

5. As with other forms
of energy pollution (such as heat and
light pollution), noise pollution
contaminants are not physical
particles, but rather waves that
interfere with naturally-occurring
waves of a similar type in the same
environment.

6. MEASURING
SOUND

7. Sound is measured by the unit
decibels (dB).
Eg:
Silence – 0 dB
Normal Conversation – 30 dB
Radio; Telephone ring; busy
traffic; orchestra; loud TV – 70 db
Shouting in one’s ear – 114 db
Volcanic Eruption – 272 db

10. Noise may permanently damage hearing. A
sudden loud noise can cause severe damage
to the eardrum.
Noise increases the chances of occurrence
of diseases such as headache, blood
pressure, heart failure, etc.
Noise leads to increased heart
beat, constriction of blood vessels and
dilation of pupil.
Noise is a problem especially for patients
who need rest.
Noise may cause damage to liver, brain

13. Noise can have a detrimental effect on
animals, increasing the risk of death by
changing the delicate balance in predator
or prey detection and avoidance, and
interfering the use of the sounds in
communication especially in relation to
reproduction and in navigation.
Acoustic overexposure can lead to
temporary or permanent loss of hearing.

14. 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.
Noise pollution has caused the death of
certain species of whales
That beached themselves after being
exposed to the loud sound of
military sonar.

17. Noise pollution has
many effects on plants:
It affects their growth
and some may even die
due to very loud noise.
It affects the

19. Community development or urban
management should be done with long-term
planning, along with an aim to reduce noise
pollution.
Social awareness programs should be taken
up to educate the public about the causes and
effects of noise pollution.
Minimization of domestic noise coming from
radio , tape recorders , television sets , mixers
, washing machine , etc. by their selective and
judicious use.

20. the usage of loudspeakers in the
habitant zones should not be
permitted.
noise pollution can be reduced to
certain limit by fixation of silencers in
automobiles.
reduction of excess noise levels by
optimum selection of machinery tools
or equipment.
