The charts provide data on how many people were affected by four different types of noise, namely traffic, train, aircraft, and industry during the day and at night in both urban and rural areas in the year 2007.
Overall, it can be seen that traffic was the predominant factor on the rankings, while industry factors just had least impacts on both settings. In addition, noise levels during the day were higher than those at night, and city dwellers were more affected compared to their rural counterparts.
Regarding traffic and train factors, the number of people living in the city exposed to traffic noise during daytime and at night were at 64 million and 48 million respectively, which were nearly two times higher than the figures for rural areas, with the former at 34 million and the latter at 24 million. Moreover, there were 10 million and 8 million city dwellers affected by train noise in the daytime and at night, respectively, while this was the case for 8 million and 6 million in rural citizens.
Turning to the two remaining factors, 4 million city inhabitants were impacted by aircraft noise during the day, which was about two times higher than that for rural individuals in the same factor, whereas these numbers fell significantly at night, both to 1 million. However, noise from industry just impacted 1 million city individuals in the daytime and 0.25 million at night, while not affecting rural people.
