Noise causes psychological and physiological disorders in humans. Three ways by which noise (sound) pollution affects the human bodies are-

  1. Chronic exposure to a relatively lower noise level of cities may permanently damage the hearing abilities of humans.
  2. Noise also causes sleeplessness, increased heart beating.
  3. Noise alters breathing patterns, thus considerably stressing humans.

Three ways to reduce noise pollution -

  1. Reduction of noise in our industries can be affected by the use of sound-absorbent materials or by muffling noise.
  2.  Stringent following of laws laid down in relation to noise like delimitation of horn-free zones around hospitals and schools.
  3.  Permissible sound-levels of crackers and of loudspeakers, timings after which loudspeakers cannot be played, etc., need to be enforced to protect ourselves from noise pollution.
