Internationally accepted exposure-response relationships show that railway noise causes less annoyance than road traffic and aircraft noise. Railway transport, both passenger and freight transport, is increasing, and new railway lines are planned for environmental reasons. The combination of more frequent railway traffic and faster and heavier trains will,(More)
background, aim, method, result) max 200 words: Trucks up to 25.25 metres in length and weighing up to 60 tonnes are permitted in domestic traffic in Sweden. This deviates from the EU standard, according to which trucks are not to be longer than 18.75 metres or weigh more than 40 tonnes. The Ministry of Enterprise, Energy and Communications has commissioned(More)
BACKGROUND A substantial increase in transportation of goods on railway may be hindered by public fear of increased vibration and noise leading to annoyance and sleep disturbance. As the majority of freight trains run during night time, the impact upon sleep is expected to be the most serious adverse effect. The impact of nocturnal vibration on sleep is an(More)
In order to mitigate the negative effects of transportation and to achieve a competitive transport sector, infrastructure charges in the European Union should be based on short-run marginal costs. This paper shows that railway-noise charges can be estimated using already obtained knowledge of monetary and acoustical noise evaluation. Most European countries(More)
This paper evaluates the relative contribution of vibration and noise from railway on physiological sleep outcomes. Vibration from railway freight often accompanies airborne noise, yet is almost totally absent in the existing literature. In an experimental investigation, 23 participants, each sleeping for six nights in the laboratory, were exposed to 36(More)
The aim of this study is to compare vibration exposure to noise exposure from railway traffic in terms of equal annoyance, i.e., to determine when a certain noise level is equally annoying as a corresponding vibration velocity. Based on questionnaire data from the Train Vibration and Noise Effects (TVANE) research project from residential areas exposed to(More)
Chalmers Publication Library (CPL) offers the possibility of retrieving research publications produced at Chalmers University of Technology. It covers all types of publications: articles, dissertations, licentiate theses, masters theses, conference papers, reports etc. Since 2006 it is the official tool for Chalmers official publication statistics.

A “bonus” of 5 dB has been applied to railway noise in most European Union (EU) countries, e.g. Austria, Germany, France and Sweden. The reason for this is that the majority of international and Swedish studies show that railway noise is less annoying than road traffic noise and aircraft noise (Miedema & Oudshoorn 2001; EU position paper 2002). According to(More)
In accordance with the EU energy policy, wind turbines are becoming increasingly widespread throughout Europe, and this trend is expected to continue globally. More people will consequently live close to wind turbines in the future, and hence may be exposed to wind farm noise. Of particular concern is the potential for nocturnal noise to contribute towards(More)
