Taking the city of Angers as its field of investigation, this paper sheds light on the way municipal services respond to complaints about noise pollution and use this phenomenon as a category of public responsibility. As part of a more general debate on noise as a “product,” being itself an agent and an indicator of power relationships as stressed by Michel Foucault’s work on “biopower,” norms, and control, the study sets out to describe the multiple circuits followed by noise-related complaints and the dimensions of their interpretation during the interactions between complainants and those dealing with them.
