  1. 16. Excitation of Tyre Vibrations due to Tyre/Road Interaction

    Författare :Frédéric Wullens; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tyre road interaction; tyre road noise; tyre structure modelling; contact modelling;

    Sammanfattning : Tyre/road noise is the main contributor to road traffic noise at speeds above 40 km/h for passenger cars and above 70 km/h for heavy trucks. Research has been carried out during the last thirty years in order to understand and quantify the generation mechanisms responsible for tyre/road noise. LÄS MER

  3. 17. Health effects of road traffic noise in childhood and adolescence

    Författare :Alva Käte Enoksson Wallas; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Traffic noise is an increasing environmental exposure, primarily as a consequence of continuous urbanisation and growth of the transport sector. The burden of disease from noise is the second highest in Europe among all environmental exposures, after air pollution, and WHO recently proposed more strict environmental noise guidelines. LÄS MER

  4. 18. The urban form and the sound environment - Tools and approaches

    Författare :Laura Estévez Mauriz; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; road traffic noise; prediction; Urban sound planning; modelling; quiet side; urban systems; traffic dynamics;

    Sammanfattning : Cities are always confronted with transition and adaptation. Awareness on urban environmental quality is leading the vision about the built environment’s resilience and sustainability, highlighting the importance of a multidisciplinary framework for urbanisation processes.

  5. 19. Urban Sound Planning - An attempt to bridge the gap

    Författare :Laura Estévez Mauriz; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; prediction methods; road traffic noise; traffic dynamics; Urban sound planning; quiet side; urban systems; citizen participation; urban strategies;

    Sammanfattning : Cities are constantly between transition and adaptation, where current urban development needs a consistent strategic solution capable of understanding and including the relationships between urban form, environment and urban life. Awareness of the quality of the urban environment is leading the vision on the resilience and sustainability of the built environment, highlighting the importance of a multidisciplinary urban framework.

  7. 20. The simulation of car and truck tyre vibrations, rolling resistance and rolling noise

    Författare :Carsten Hoever; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; rolling resistance; rolling noise; tyres; vibrations; waveguide finite element; tyre road interac- tion; BEM; fuel efficiency; parameter study; road surface properties; numerical modelling;

    Sammanfattning : The road transportation sector places a severe burden on the environment in the form of CO2 emissions and road traffic noise. Both of these environmental prob- lems can be related to car and truck tyres. LÄS MER
