The research question is: "How to develop and apply acoustic artefacts and design method-ologies for improving soundscapes in urban outdoor spaces?" In the project, this research question is limited to one specific type of urban outdoor space – city-park – and to two types of acoustic design artefacts. These are: I. Dynamic promotion of qualitative site specific sounds (e.g., the overall site specific sonic atmosphere, sounds from activities, birds and fountains), which creates an improved soundscape. II. Sound-art installations, that creates de-limited auditory sub-spaces within the park/square.
