Factors moderating people's subjective reactions to road noise (vor Ort)

Abstract:
The objective of the FAMOS project was to develop a European guide-book with practical applications for the National Road Administrations on how to handle noise annoyance by non-acoustic moderators in planning of roads, road enlargement as well as road maintenance.When the road administrations have used all technically feasible and economically possible measures to reduce the noise, there can still be a need for further reduction of the annoyance. Analyses reveal that only about 1/3 of the variance in the annoyance response is caused by the noise level itself, whereas the other 2/3 are determined by so-called non-acoustic factors. The annoyance response therefore can be altered without changes to the actual noise level. The FAMOS project will quantify how different factors modify people's subjective reactions to road traffic noise. Reports from previous surveys have been analysed in order to describe the different annoyance moderators and experimental tests using sound walks, questionnaires and listening tests have been performed. Various methods have been used to find, extract and analyse data and turn the results into models formulated for practical use with illustrative examples.
