The political voice is the subject of the second volume of Sonic Urbanism publications. This volume explores the political voice as a particular sonic phenomenon, asking how and where it is possible to have a voice in urban politics, the relationship between material and metaphorical readings of political speech, and how voices can be amplified or silenced in cities. Responses explored vocal contestations and noisy citizenship, technologies that transmit or transform voices, and the ways that sound art and experimental music stage collective voicings.
