The bar charts illustrate the quantities of European residents who were disturbed by noise pollution in day and night in cities and rural areas in the year 2007.
Overall, the majority of the citizens suffered from traffic noises which affected city dwellers more than those in the countryside. Conversely, industry noise pollution in both regions had negligible effects.
Regarding the first chart, traffic pollution in the daytime received the most complaints, with 64 million city inhabitants reporting, while nearly half of those surveyed said to be disturbed at night. A comparable pattern was observed in train pollution where roughly one out of ten citizens suffered from noise pollution in either day or night. By contrast, noise pollution from aircraft was far less significant, with 4 million people disturbed in the daytime and 4 million in at night. Similarly, almost none of the inhabitants dealt with noise pollution from industries.
It is apparent that suburban areas had the same pattern as cities. More than half of the people faced traffic noise pollution in day, followed closely by 24 million at night. Train pollution only affected one-tenth of the residents in either day or night, at 8 million and 6 million respectively. Surprisingly, only a modest numbers of the citizens struggled with aircraft noises in both day and night time, while exactly none responded to be disturbed by industry noises.
