  1. 1. 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.

  3. 2. 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.

  4. 3. Prediction of Traffic Noise Shielding by City Street Canyons

    Författare :Mikael Ögren; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : 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.

  5. 4. Active Galactic Nuclei in galaxy surveys : Empirical paths to the fiery hearts of cosmic beasts

    Författare :Beatriz Villarroel; Andreas J. Korn; Takis Konstantopoulos; Moshe Elitzur; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Astronomy; Astronomi;

    Sammanfattning : Some galaxies emit excessive amounts of light from their centers, caused by accretion of gas onto super-massive black holes (SMBH). These galactic cores are often referred to as Active Galactic Nuclei (AGN) and they come in many different forms, distinguishable by their emission properties. LÄS MER

  7. 5. Numerical modelling of sound propagation to closed urban courtyards

    Författare :Maarten Hornikx; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; courtyard; urban noise abatement schemes; pseudospectral; road traffic noise; equivalent sources method; scale model study; urban canyon;

    Sammanfattning : Because modern urban environments suffer from excessive levels of road traffic noise, access to closed courtyards is essential in order to offer urban sound environments of high quality with regard to health and perceived sound. To reach this quality, which is described by the quiet side definition, the 24-hour equivalent noise level should be below 45 dB(A). LÄS MER
