         In order to control noise pollution , a number of measures should be taken .Silencing devices can be used in engines and industrial machines. Also,one should wear earplugs in places with too much noise.There must be a law to control using horns and loudspeakers in public places.As well as,spreading awareness among people about the causes and effects of noise pollution can contribute to controlling it.Moreover,planting trees helps in absorbing noise.Furthermore,factories should be located away from the residential areas.

         Finally,it is clear that noise pollution has harmful effects on man and that no one can escape from noise in modern life.So both government and individuals must take their measures to control noise pollution,live peacefully and enjoy peace mind.
