Traffic noise is considered as one major source of noise annoyance in urban context indicated by the increasing number of complaints. The neglect of quality parameters regarding pass-by noise appears as a basic cause for the unreduced annoyance. Several parameters besides the SPL have an important influence on noise evaluation, such as low frequency contributions, temporal aspects or noise patterns. The European research project Quiet City Transport (6FP PL516420) was motivated by the EU Noise Directive 2002/49/EC and is dealing with vehicle pass-by noise and its evaluation in order to identify promising noise mitigation measures. In this framework a quantitative description of noise annoyance using psychoacoustic descriptors was achieved. By means of the detected metric certain perceptual-relevant aspects, such as the difference between diesel and gas, can be reconstructed. Furthermore, the development of a synthesis tool makes the simulation and binaural auralization of pass-by noise, traffic noise as well as specific vehicle noise sources possible. Based on the presented technique the detailed investigation of causes for noise annoyance is carried out. The results will be presented.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
