Flowchart of the selection process (based on the PRISMA Statement [e7])

*The exposure information in the studies by Wiens (27) and Evrard (19) differs considerably from the exposure information of the remaining studies and thus were not included in the meta-analysis: Wiens (27) only collected data on perceived annoyance, but not aircraft noise levels;

Evrard (19) did not perform any individual, address-based estimation of the aircraft noise.
