The history of the creation and activities of the Lodz Ghetto is a tale of escalating terror techniques. The structure of repression included isolation, starvation, slave labor, persecution on personal, cultural and religious grounds, as well as measures that reinforced social and material stratification. Against this background, practices of resistance of an acoustic nature – one of the few forms of resistance that could slip through the dense web of oppression – take on particular significance. Acoustic strategies of survival include, on the one hand, artistic creation or singing during work, strikes and opposition gatherings, and on the other, practices that ensured survival: deliberate silence, listening to the radio, or secret communication systems between those in hiding. The article illustrates the multifaceted nature of the resistance undertaken by those imprisoned in the ghetto, emphasizing the importance of sound strategies – hitherto overlooked in Holocaust studies.
