Perceived Noise Annoyance Caused by Maglev Trains: Final Scientific Report
2005 (English)Report (Other academic)
The underlying study aimed at quantifying the impact of sound caused by high speed magnetic levitation transport systems on perceived noise annoyance in a realistic setting. An innovative system was implemented for selecting representative participants from the Dutch population, as regards age, gender, level of education noise sensitivity reported anxiety, pre-exposure to train and road traffic noise, general quality of the living environment, and general health. It was grounded in 1500 participants’ responses to a specifically constructed questionnaire, which contained items from a nation-wide Dutch and Eurobarometer surveys. Finally 80 (+21) representative participants were selected. During the experiment, which took place in a realistic setting (living room of holiday cottage), groups of 5-7 participants were asked to be seated, relax, reading a magazine or newspaper and were served refreshments. During their stay, traffic noise was reproduced in an ecologically valid way in outdoor loudspeakers. Every 10 min, the participants were asked to assess traffic noise annoyance. At the beginning and after at least 1 hour of the experiment, participants were also asked to scale the annoyance of a set of 7 reference sounds utilized for master scaling. Based on this study, we found that there is no evidence to expect a significant difference in noise annoyance caused by Maglev and TGV trains at the same average façade exposure. Noise annoyance caused by conventional trains was not found to be significantly lower than annoyance caused by these high-speed trains at the same average façade exposure (tested up to 65 dB(A) only). The latter conclusion is in contradiction with earlier work by Vos et al. A comparison to the work of Neugebauer at al. came out inconclusive: although these authors state there is a distinct difference between the two types of trains investigated, their actual results fall within the spread of annoyance levels due to distance to the track and vehicle speed that we observed. Field surveys have shown that for the same average sound level, railway noise causes less annoyance than dense road traffic noise, at least for certain interval of levels. Although our study included several of the factors that may contribute to this effect, we could not observe it, except when the results were limited to sounds recorded at a distance of over 100 m.
