Question

what are the sources of noise pollution in the seas? In which countries it is the most?​

Answer 1

To date, the increase in beached whales, sperm whales and other cetaceans around the world has been put down to the greater noise levels caused by fishing, sea trade, military maneuvers, and the construction of oilrigs and offshore wind farms.

Guangzhou, China, ranked as having the worst levels of noise pollution in the world, followed by Cairo, Paris, Beijing and Delhi. Of the 50 cities, Zurich was found to have the least noise pollution. Participants in Delhi recorded the highest average hearing loss – equivalent to someone 19.34 years older than them.

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.

• Air traffic noise.

• Construction sites.

• Catering and night life.

• Animals.

• Physical.
