Noise levels upto 64 dB (decibel) is well tolerated. Prolonged exposure to noise levels of 80 dB or more leads to loss of hearing ability, fatigue, nervousness, fever, hypertension, gastric disorders, increase in cholesterol and dilation of the pupil of the eyes. As jet aeroplanes produce loud noise - upto 150-160 dB or more, inhabitants in the vicinity of busy airports are likely to experience such health hazards. The highest noise level has been reported to be in rockets, that is 180 dB.
