Aural identity, neighborhood and community

Central to the notion of a sound ecology is the role of sound in the definition of place – more than a notion of diffuse and abstract space. One of its goals is to document this role and determine the daily rhythms of a community. What defines an acoustic community is the existence of soundmarks. The boundary of each community is defined precisely by the limits drawn by the acoustic horizon of these unique sounds. When noise is so intense that obliterates all the soundmarks, it prevents the exchange of words and does not create singular identity but solitary individualism, we are facing a non-place. Our thesis is that spaces occupied by an undifferentiated and insignificant sound mass – traffic noise, for example – where we tend to isolate ourselves, are homogeneous universes which eliminate the singular identity of the individual or the group.
