There have been an increasing number of complaints and lawsuits about noise pollution in some major
world cities.The problem with noise is not only that it is unwanted,but also that it negatively
affects human health and well being.In my opinion,the government should attach importance to the
research and application of technology in order to reduce noise pollution.First,the application of
sound absorbing or sound insulation material shows the quickest sign of the reduction of noise
pollution.Noise inside a building can be reduced,if both the external and internal walls are made of
sound deadening materials.Heavy and dense materials such as masonry or brick walls are better for
sound reduction.The application of sound reduction materials is economically and technically
feasible in dealing with four main noise sources,namely transportation,industrial production,
construction,and social activities.Furthermore,the introduction of hybrid cars has made advances in
the reduction of motor vehicle noise.Noise from transportation is one major source of noise
pollution.The application of cars with low level noise will be effective in reducing noise emission.
In conclusion,with people exposed to dangerous sound levels on the rise,noise pollution has become
a common occupational and environmental hazard.I strongly recommend that the government should spare
no efforts in funding and investing in new technologies which will be essential in noise pollution
reduction.
