The bar charts compare the number of people in cities and rural areas annoyed by four kinds of noise pollution during the day and night.
Overall, what immediately stands out when examining the data is that traffic was the primary contributor to noise pollution in both places, in stark contrast to industry. Citizens suffered more from this issue than their rural counterparts, with the noise levels being more intense during the day.
Both urban and rural residents were predominantly irritated by traffic. In cities, 64 million people suffered from noise over the daytime, nearly double the figure for their rural counterparts (34 million). During the day, the number of those affected dropped to 48 million for cities and 24 million for the countryside.
The impact of the remaining factors, namely train, aircraft, and industry, was significantly lower. Regarding trains, the figures for affected residents in cities were consistently 2 million higher than those in rural areas (10 versus 8 for day, and 8 compared to 6 for night, respectively). While the data for aircraft in cities doubled that of rural areas during the day, both places demonstrated an identical number of victims at nighttime. Notably, only in urban areas did people suffer from industrial noise, though the numbers were insignificant, with 1 million people during the day and 0.25 million people at night.
