New Technology Is One Way to Solve Noise Pollution
新技术是解决噪音污染的举措之一。
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.
在世界的许多城市中，人们对噪音污染的抱怨越来越多。我们不仅讨厌噪音问题，它还会影响我们的身体健康。我认为，政府应该重视对于技术的研究和利用，这样我们才能减少噪音污染。
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 feasiblein 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 motorvehicle 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.
首先，利用吸收噪音或是隔音的材料可以迅速减少噪音污染。建筑室内的噪音也可以得到减少，前提是外墙和内墙都要运用这种隔音材料。例如石造建筑和砖壁这样的厚实材料也可以很好地达到减少噪音的效果。利用降音材料既省钱，在技术上也能够达到，用它们我们能够解决四大噪声来源，它们是交通、工业生产、建筑、社会活动。此外，混合动力汽车的应用也可以减少汽车带来的噪音。交通噪音是噪音污染的主要来源。使用低噪声的汽车可以有效地减少噪音排放。
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.
总结，人们接触有害声音的次数正在不断增长，噪声污染已经对环境造成了伤害。我强烈认为政府应该不遗余力地加强新技术的投资，这对减少噪音污染是非常重要的。
