An examination of the role of sound in defining the city in the context of Edinburgh

The surfeit of generic and place-specific sounds that exist in the urban environment contribute to what has been referred to as the soundscape. Within the built environment sound has the potential to create thresholds and acoustic territories that define and colour the experience and social functioning of inhabited spaces. In this research, a robust critical examination of the literature by prominent sound artists and theorists is used to illustrate how sound contributes to the urban experience. This is reinforced by primary research undertaken in the city of Edinburgh where the analysis and synthesis of these secondary sources is tested using bespoke soundworks to determine the ways in which sound contributes to our perception, reading and understanding of our physical environment. This research concludes by illustrating the potential for the future, technological development of the soundscape.

An Integrated approach to street canyon pollution modelling.

An integrated method for the prediction of the spatial pollution distribution within a street canyon directly from a microscopic traffic simulation model is outlined. The traffic simulation package Paramics is used to model the flow of vehicles in realistic traffic conditions on a real road network. This produces details of the amount of pollutant produced by each vehicle at any given time. The authors calculate the dispersion of the pollutant using a particle tracking diffusion method which is superimposed on a known velocity and turbulence field. This paper shows how these individual components may be integrated to provide a practical street canyon pollution model. The resulting street canyon pollution model provides isoconcentrations of pollutant within the road topography.
