Noise-related annoyance increased since 2005

NORAH is not the first study to investigate to what extent people in the Rhine-Main region are disturbed by traffic Noise. As far back as 2005, the so-called RDF Study commissioned by the Regional Dialogue Forum Frankfurt Airport asked the residents living in the environs of the airport to assess their noise-related annoyance on a scale of 1 to 5. Anyone who selected 4 or 5 was automatically included in the group of the "highly annoyed". The NORAH team adopted a similar approach to calculate how high the proportion of "highly annoyed" persons is for the different noise levels. The result of the comparison: in 2005 there were substantially fewer people in all Sound level classes who felt highly or extremely annoyed by air Traffic noise. At the three other airports investigated by NORAH the proportion of "highly annoyed" persons was also above the values measured in 2005 in the Frankfurt region.
