German Environmental Survey, GerES


Chemicals, mould or noise – people are exposed every day to potentially harmful influences from the environment. In the German Environmental Survey, the Federal Environment Agency is investigating the exposure of the population to pollutants and other environmental effects such as noise. It is thereby contributing to the protection of people and the environment. read more

Indicator: Population exposure to traffic noise

A graph shows the number of people exposed to traffic noise above 65 decibels throughout the day in 2017 – 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 2017, the health of about 4.7 million people was affected by night-time noise. Throughout the day, noise affected the health of at least 3.3 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
