Indicator: Population exposure to traffic noise

A graph shows the number of people exposed to traffic noise above 65 decibels throughout the day in 2012 – and those exposed to over 55 decibels between 10 p.m. and 6 a.m. It differentiates between road, aircraft and rail traffic noise.

In 2012, the health of 4.8 million people was affected by night-time noise. Throughout the day, noise affected the health of 3.5 million people.The main source of noise is road traffic. Rail traffic is particularly relevant at night. Overall, aircraft noise plays only a minor role.Noise that exceeds exposure limits can lead to health problems. read more
