EFFECTS 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 .

  aggression, hypertension, high stress levels,
  hearing loss, sleep distrubances, and other
  harmful effects.

  cardiovascular effects and exposure to moderately
  high levels during a single eight hour period
  causes a statistical rise in blood pressure.
