Noise pollution is one of the most serious drawbacks that people who live in a big city have to face.
Firstly, the city is always noisy, even at night.
Its main cause comes from outdoor noise sources such as heavy traffic or construction sites.
Deafening vehicle engines and horns on the busy streets are very annoying.
Buildings are always knocked down and rebuilt.
Secondly, indoor noise sources such as household machines, and loud music also help to worsen the noise pollution.
In offices, photocopiers, coffee makers, telephone ring and lighting fixtures all contribute to the cacophony of noise.
Last but not least, noise from people themselves aggravates the situation.
Big cities are densely populated with oceans of people.
Their laughing, chatting and talking at the same time causes unpleasant sounds.
To conclude, noise pollution, which has many negative impacts on people’s health such as sleep disturbance, stress, raised blood pressure, dull hearing, and even loss of hearing, is a big disadvantage of city life.
