1. Prediction and Optimisation of Traffic Noise. A Study on Noise Barriers and Shielded Areas
Abstract : The main contribution of noise levels in cities is today road traffic. The strongest source for all road vehicles is most often the tyre-road contact. This source position close to the ground is fortunate with respect to secondary noise abatement measures, such as absorbing road surfaces or noise barriers. READ MORE

2. Road traffic noise reduction by multiple scattering and absorption mechanisms
Abstract : Millions of people in Europe, and even more on a global scale, are affected by environ- mental noise. Traffic related noise is estimated to cause a yearly loss of approximately one million healthy life years in Western Europe, which is mostly related to road traffic noise. READ MORE

3. Prediction of Traffic Noise Shielding by City Street Canyons
Abstract : Reducing the sound level on the exposed building facades due to traffic noise in cities is difficult and expensive. Creating access for the inhabitants to a quiet side can be an alternative method for reducing the annoyance. Therefore it is of interest to predict the level on shielded positions such as courtyards.

4. Individual Preferences, Choices, and Risk Perceptions - survey based evidence
Abstract : Paper 1 investigates how birth order and having siblings affect positional concerns in terms of success at work and of income. We find that only-children are the most positional, but that number of siblings increases the concern for their position among those who grew up together with siblings. READ MORE

5. Road Traffic Noise - Factors modifying its relation to annoyance and cardiovascular disease
Abstract : Traffic noise causes annoyance and sleep disturbance and has been linked with several other adverse effects on life quality and health, including increased risk of hypertension and myocardial infarction. Conservative estimates assume that at least one million healthy life years are lost every year from traffic related noise in the western part of Europe. READ MORE
