14.  It can cause hypertension, high stress
levels, tinnitus, hearing loss, sleep
disturbances, and other harmful
effects.
 Chronic exposure to noise may cause
noise-induced hearing loss

17. Control of Noise PollutionControl of Noise Pollution
The source of noise must be reduced.
The acoustical furnishing must be done so
that the sound can be absorbed.
The path of transmission of sound must be
stopped and the receiver of noise must be
safeguarded.
The amount of traffic must be reduced
near the residential homes, educational
institutes and hospitals.
Noise producing industries, airport, bus
stations, transport terminals and railway
stations to sighted far from where living
places
