POLLUTION 
WHAT IS N
OISE 
? 
 The word noise comes from the Latin word nauseas, meaning 
seasickness. 
 Sound that is unwanted or that disrupts the activity or balance 
of human or animal life is called as noise. When there is lot of 
noise in the environment, it is termed as noise pollution. 
 Sound becomes undesirable when it disturbs the normal 
activities such as working, sleeping, and during 
conversations. It is an underrated environmental problem 
because of the fact that we can’t see, smell, or taste it. 
 World Health Organization stated that “Noise must be 
recognized as a major threat to human well-being” 
SOURCES OF NOISE POLLUTION 
Transportation systems are the main source of noise 
pollution in urban areas. 
  Construction of buildings, highways, and streets 
cause a lot of noise, due to the usage of air 
compressors, bulldozers, loaders, dump trucks, and 
pavement breakers. 
 Industrial noise also adds to the already unfavorable 
state of noise pollution. 
  Loud speakers, plumbing, boilers, generators, air 
conditioners, fans, and vacuum cleaners add to the 
existing noise pollution. 

Effect Of Noise Pollution On 
Humans 
 Chronic exposure to noise may cause noise-
induced hearing loss. Older males exposed to 
significant occupational noise demonstrate 
significantly reduced hearing sensitivity than their 
non-exposed peers. 
  Unwanted noise can damage physiological and 
psychological health. Noise pollution can cause 
annoyance and aggression, hypertension, high 
stress levels, tinnitus, hearing loss, sleep 
disturbances, and other harmful effects. 
 . 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.. 

Effect On Animals & 
Aquatic Life 
• 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 
•  rAenp riomdpuaccttio onf  .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

NOISE CONTROL 
STRATEGY
 Planting bushes and trees in and around sound generating 
sources is an effective solution for noise pollution. 
  Regular servicing and tuning of automobiles can effectively 
reduce the noise pollution. 
  Buildings can be designed with suitable noise absorbing 
material for the walls, windows, and ceilings. 
 Workers should be provided with equipment's such as ear plugs 
and earmuffs for hearing protection . 
  Similar to automobiles, lubrication of the machinery and 
servicing should be done to minimize noise generation. 
 Soundproof doors and windows can be installed to block 
unwanted noise from outside. 
  Regulations should be imposed to restrict the usage of play 
loudspeakers in crowded areas and public places. 
  Factories and industries should be located far from the 
residential areas 
 Community development or urban management should be 
done with long-term planning, along with an aim to reduce

public about the causes and effects of noise pollution.
