Sound pollution Noise pollution

Posted by at

Sound pollution or 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 DJ, Music System, machines and transportation systems, motor vehicles, vehicle’s horn, aircraft, and trains.

Noise pollution effects both health and behavior. Unwanted sound (noise) can damage psychological health. High noise levels effects are

  • Cardiovascular effects in humans
  • Rise in blood pressure
  • Increase in stress
  • Vasoconstriction
  • Increased incidence of coronary artery disease
  • In animals, noise can increase the risk of death by altering predator or prey detection and avoidance/li>
  • Interfere with reproduction and navigation, and contribute to permanent hearing loss.

How Does Noise Pollution Harm Your Heart?

According to research published in Environmental Health Perspectives, long-term exposure to traffic noise may account for approximately 3 percent of coronary heart disease deaths (or about 210,000 deaths) in Europe each year.8 But how exactly does noise harm your heart?

One of the key ways is by elevating stress hormones such as cortisol, adrenaline, and noradrenaline, which, over time, can lead to high blood pressure, stroke and heart failure. One review of research showed that “arousal associated with nighttime noise exposure increased blood and saliva concentrations of these hormones even during sleep.”9 Deepak Prasher, a professor of audiology at University College in London and a member of the WHO Noise Environmental Burden on Disease working group, states:10

    “Many people become habituated to noise over time… The biological effects are imperceptible, so that even as you become accustomed to the noise, adverse physiological changes are nevertheless taking place, with potentially serious consequences to human health… Taken together, recent epidemiologic data show us that noise is a major stressor that can influence health through the endocrine, immune, and cardiovascular systems.”

The impact can be significant. Among women who judge themselves to be sensitive to noise, chronic noise exposure increased the risk of cardiovascular mortality by 80 percent!11 Chronic noise exposure also leads to health risks beyond your heart, such as hearing loss, diminished productivity, sleep disruption, impaired learning and more. Air pollution similarly causes wide-reaching risks to health…

Unfortunately in India people have no awareness of sound pollution. Please be aware and educate other people about harmful effect of sound pollution.
