The bar graphs illustrate the number of people affected by four types of noise pollution during the day and at night in both urban and rural areas, measured in millions.
Overall, traffic noise affected by far the largest number of people in both areas, whereas industrial noise had the smallest impact. Additionally, daytime figures were consistently higher than nighttime figures across all categories, while the numbers for train and aircraft noise were relatively similar.
Looking first at the city, significantly more people were exposed to noise pollution during the day than at night. Traffic noise accounted for the highest figures, affecting 60 million people in the daytime compared to 48 million at night. Similarly, train noise impacted 10 million people during the day, while the figure fell slightly to 8 million at night. In terms of aircraft noise, 5 million people were affected in the daytime, compared with only 3 million at night. Industrial noise was responsible for the lowest figures overall.
Turning to rural areas, traffic noise again represented the largest category, affecting approximately 35 million people during the day and 25 million at night. The number of people influenced by train noise stood at 8 million in the daytime and 6 million during the night. Likewise, aircraft noise affected 4 million people during the day, whereas the nighttime figure was only 2 million. Finally, no people were affected by industrial noise in either period.
