These results corroborate an earlier UBA study on pharmaceutical drugs which showed a higher incidence of prescriptions for persons exposed to night-time aircraft noise. A large-scale study done in the vicinity of various European airports (HYENA study) in 2008 also determined noise-related health risks, namely that persons with greater exposure to night-time aircraft noise often have higher blood pressure than persons who reside in quieter residential areas. “The latest results demonstrate that we must do more to protect citizens from noise. In the name of sustainable mobility we must take a critical look at which night-time flight activity is really necessary”, said UBA President Jochen Flasbarth.

The Cologne-Bonn airport has volunteered to undertake noise abatement measures which, although they reduce noise risk, are unable to completely prevent the health impact of aircraft noise. On account of special conditions which exist at the Cologne-Bonn airport (it has a relatively high volume of night-time flight activity), further analyses should follow since, for example, there is no answer as yet to whether the results of the study relating to risk exposure due to night-time aircraft noise are directly applicable to other airports.
