Noise pollution presentation

  1. 1. Cause and effect of Noise Pollution
  2. 2. What is Noise ?The word noise comes from the Latin word nauseas, meaning seasickness.
  3. 3. What is Noise ? Sound that is unwanted or that disruptsthe 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.
  4. 4. What is Noise ?Sound becomes undesirable when it disturbs the normal activities such asworking, sleeping, and during conversations. It is an underrated environmental problem because of the fact that we can’t see, smell, or taste it.
  5. 5. What is Noise ? World Health Organization stated that “Noisemust be recognized as a major threat to human well-being”
  6. 6. Sources of Noise Pollution > Transportation systems are the mainsource of noise pollution in urban areas.> Construction of buildings, highways, andstreets cause a lot of noise, due to the usageof air compressors, bulldozers, loaders, dumptrucks, and pavement breakers.
  7. 7. Sources of Noise Pollution> Industrial noise also adds to the alreadyunfavorable state of noise pollution. > Loud speakers, plumbing, boilers,generators, air conditioners, fans, and vacuumcleaners add to the existing noise pollution.
  8. 8. Effect Of Noise Pollution On Humans 1. Chronic exposure to noise may cause noise-induced hearing loss. Older males exposed to significant occupational noisedemonstrate significantly reduced hearing sensitivity than their non-exposed peers.
  9. 9. Effect Of Noise Pollution On Humans 2. Unwanted noise can damage physiological and psychological health. Noise pollution cancause annoyance and aggression, hypertension, high stress levels, tinnitus, hearing loss, sleep disturbances, and other harmful effects.
  10. 10. Effect Of Noise Pollution On Humans 3. High noise levels can contribute to cardiovascular effects and exposure tomoderately high levels during a single eight hour period causes a statistical rise in blood pressureof 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..
  11. 11. Effect On Animals & Aquatic Life 1. Noise can have a detrimental effect on animals, increasing the risk of death bychanging 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 . .
  12. 12. Effect On Animals & Aquatic Life 2. An impact of noise on animal life is the reduction of usable habitat that noisy areas may cause, which in the case of endangeredspecies 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 .
  13. 13. Effect On Animals & Aquatic Life3. Some other effects on wildlife & aquaticanimals are:> Hormone Imbalance> Chronic Stress> Panic & Escape Behavior> Abandonment of Offspring> Injury> Increase in Loudness of Inter speciescommunication .
  14. 14. Noise Measurement
  15. 15. Noise Measurement
  16. 16. Noise Measurement
  17. 17. Noise Measurement
  18. 18. Noise Measurement
  19. 19. Noise Control Strategy> Planting bushes and trees in and around soundgenerating sources is an effective solution fornoise pollution.> Regular servicing and tuning of automobilescan effectively reduce the noise pollution.> Buildings can be designed with suitable noiseabsorbing material for the walls, windows, andceilings.
  20. 20. Noise Control Strategy > Workers should be provided with equipmentssuch as ear plugs and earmuffs for hearingprotection .> Similar to automobiles, lubrication of themachinery and servicing should be done tominimize noise generation.> Soundproof doors and windows can be installedto block unwanted noise from outside.
  21. 21. Noise Control Strategy > Workers should be provided with equipmentssuch as ear plugs and earmuffs for hearingprotection .> Similar to automobiles, lubrication of themachinery and servicing should be done tominimize noise generation.> Soundproof doors and windows can be installedto block unwanted noise from outside.
  22. 22. Noise Control Strategy> Regulations should be imposed to restrict theusage of play loudspeakers in crowded areas andpublic places.> Factories and industries should be located farfrom the residential areas>Community development or urban managementshould be done with long-term planning, alongwith an aim to reduce noise pollution>
  23. 23. Noise Control Strategy> Social awareness programs should be takenup to educate the public about the causes andeffects of noise pollution.
