  • Sonification of Emergent Urban Events with Granular Synthesis as an Urban Design Tool



  • Parallel to the increase in problems due to contemporary urbanization, it is not possible to state that today’s cities are better analyzed, designed or known, all yielding to a current crisis of comprehensibility. One set of the reasons has to do with the qualitative change in the urban realm, while another set of reasons arise out of the tools we try to understand our cities with.

    Rapid urbanization brings unexpectedly dynamic problems in certain parts of the world. In addition, technological advances increase mobility and communicative connectivity. Clearly these new dimensions have to be included in urban analysis with their fully temporal nature and inter-scale relationships in the city. An operative framework based on the notion of ‘event’ could be devised for a novel understanding of the effects of new technologies on the emergent transformations in the city, as well as design and intervention tools, in mind.

    The old tools for urban representation such as plans, sections and maps have remained non-temporal spatial tools that reflect abstract Euclidean space ideals. With these, it is not possible to trace the temporal processes on urban networks and the environment. Mathematical and computer models devised later also relate to the same conceptual fundamentals. Following these observations and the reported insufficiencies of the tools that have been used, it seems logical to argue that new tools with digital interfaces could begin to provide a new sense of understanding and intervention.

    It is shown that the auditory sense is fit for the task of tracking emergent events with its temporal qualities and knowledge processing capacities*). Furthermore, ecological psychological principles could be used to map these events to our sensory matrix. Therefore, a sonification environment with operative principles of granular synthesis is proposed in order to explore emergent events in the temporal and multi-scalar processes such as urban mobility. Real-time applications as ongoing research show the perceptive potential for developing such a new urban design interface.
