Abstract Noise is known as one of the most frequently reported negative environmental effects of traffic. Influence of noise sensitivity on experienced stress has been investigated in numerous studies. However, its meaning is still relatively unclear in the evaluation of road and rail traffic noise and the research is still working on new rating methodologies. In a first step, pass-by road and rail vehicle noise samples were binaurally recorded under predefined conditions with a dummy head measurement system and synthetically composed to defined road and rail vehicle ensembles considering different characteristics. In the hearing tests 200 persons in different sessions were selected and tested under laboratory conditions. The annoyance of the vehicle ensembles was rated on an 11-graded interval scale (Personal Noise Ranking Scale) from “less annoying” to “very annoying” and also by a dynamometer which measures the intensity of the strength by test persons based on the Cross-Modality-Matching- Method.
