This article examines the sonic dimension of police operations and occupations by tracing how the everyday life changed sonically in favelas in Rio de Janeiro during their occupation by Pacifying Police Units. I tune into the silencing practices of these security policies and conclude that a moral silencing of a racialized and gendered class of people takes place. A focus on silence helps us to understand sound as a technology of power, which enables the Brazilian state to operate along a gendered sonic color line. The cases I discuss are two instances of silencing that are a product of the operations and occupations: first, the silencing of the soundscape of the favela during police operations, and second, the silencing of funk parties. These ethnographic instances elucidate how racialized processes of negation of black subjectivity and black cultural expressions take place in the Olympic city.
