Noise pollution affects both health and behavior. Unwanted sound (noise) can damage physiological health. Noise pollution can cause hypertension, high stress levels, tinnitus, hearing loss, sleep disturbances, and other harmful effects. Exposure to high noise levels causes hearing loss. This loss of hearing may be temporary, permanent, or a combination of both. Temporary hearing loss, also called Temporary Threshold Shift (TTS), results from exposure to short-term loud noises. Hearing loss and rapid increase in heart rate are some of the ill-effects of noise pollution on animals. High intensity sound induces fear, which can force species to abandon their habitat. Major causes / sources of noise pollution are:
(i) Industrial Sources:
(ii) Transport Vehicles:
(iii) Household:
(iv) Public Address System:
(v) Agricultural Machines:
(vi) Defence Equipment:
(vii) Miscellaneous Sources:
