Our cities are noisier than ever before. Why is this so, and what can be done about it?
You should use your own ideas, knowledge and experience and support your arguments with examples and relevant evidence.
-------------------------------------------------------
No one can deny that our cities are noisier than they were ever before. It is a serious problem, since noise pollution can cause stress, discomfort or even severe medical conditions. However, what are the main causes of this problem and how to tackle it has been a subject for debates for many years. In this essay I will try to overview some of the main aspects regarding this issue as well as provide some possible solutions.
First of all, it is not difficult to locate sources of noise in our cities. These days cars have a significant impact on noise pollution due to an increase in their numbers and in our streets. Internal combustion engine uses force from series of explosions and with hundreds of them on the roads, the noise levels can get quite high. A probable solution to this problem could be electromobiles, which use electrical motors instead of combustion engines. Electrical motors have less moving parts and then to be at least two time quieter.
Another significant source of noise is construction sites. With the increase in city population, new housing and infrastructure must be built. However, some equipment that construction workers use tends to be utterly loud. Unfortunately there is no easy way to reduce noise of this kind. Although, there is new technology, which allows to significantly lower the amount of noise coming inside our homes. It uses a special device mounted on a window and is proved to reduce noise levels by up to 90%.
In conclusion, in my opinion cars and construction sites are the largest sources of noise in our cities. This is due to an increase in their population, however this problem can be overcome with the use of more silent electrical cars and latest noise reduction technology.
