Answer 2

Answer:

There are many sources of noise pollution, but here are some of the main ones:

•  Traffic noise

Traffic noise accounts for most polluting noise in cities. For example, a car horn produces 90 dB and a bus produces 100 dB.

•  Air traffic noise

There are fewer aircraft flying over cities than there are cars on the roads, but the impact is greater: a single aircraft produces 130 dB.

•  Construction sites

Building and car park construction and road and pavement resurfacing works are very noisy. For example, a pneumatic drill produces 110 dB.

•  Animals

Noise made by animals can go unnoticed, but a howling or barking dog, for example, can produce around 60-80 dB.
