soundmap 

Lisbon Sound Map is a work in progress over five years, but with a public presentation of the first sound collections after six months. Taken from the fixed stations, the monitoring and recording of sonic territories will be done in studies, particularly those with classic sound marks and considered historical places (the Pombaline lower part of the city), those with changes in their acoustic space through erosion and urban renewal of the previous urban space (some historic districts), and finally, those who are in the process of radical change, either by the construction of buildings or through channels of communication (within the city limits or in areas where the Municipal Head of Planning allows construction).

Places, inhabited or uninhabited, always have a sound memory whose contents may or may not persist in time. Recording and understanding the maintenance and sound alterations in a given territory not only constitutes an individual memory, but above all, a collective one. The acoustic album has become an indispensable instrument and source of information essential to anthropological, sociological, cultural and urban study. With the sound mapping of a given area the assumed strategy is to first to listen to the sound complexity of the place (the users being communication elements) and, secondly, to develop new ways of listening that are revealed in knowledge and expression. The sound map in its interactive form (with the use of different support media) enables social, cultural and political use and expresses the daily life of a place that can be recreated years later, artificially or by removing the causes that coerce the acoustic space.
