Introduction
What exactly is “noise” in the urban space? With limited resources, often navigating within turbulent political and economic contexts, public officials prefer to regulate sounds that they: 1) can easily specify and identify; 2) hear as imbued with negative ramifications (for health, for the economy, for political stability, for safety, for morals, etc.), especially when they have the support of the citizenry; and 3) can combat under the auspices of scientific facts. This is not an easy task, however, as all three parameters constantly undergo change. The introduction discusses noise as entailed with spatial and ontological axes. It relates the concept of sound-politics to citizenship studies, particularly insurgent citizenship, differentiated citizenship, and microcitizenship.
