The Israeli “dispersion of population policy” established a territorial sovereignty in Palestine by placing Jewish immigrants from the Middle East and North Africa at national borders, as human frontiers. Merging the nation-state mechanisms of the territorial border and public housing, the policy segregated these immigrants in border residences, producing them as the ethno-class of Mizrahim. In later decades, however, as the territorial delineation of Israel changes, some of its earlier borders cease to function as such. Combining ethnography, textual analysis, and research in media archives, "Sonic Traces: The Sonority of Forgotten Borders" describes sounds that reverberate in forgotten border spaces as traces. These sonic traces mark the territorial violence involved in the production of national borders but also evoke different relationships in time and space, trying Mizrahi remembrance with other memories of displacement across and against national borders in Palestine, the Middle East, the Jewish diaspora, and the global South. This research draws on theorizations of linguistic structures. If the border is considered as a spatial-geographic sign, the sonic trace exists as part of a destabilized relationship between the signifier and signified; between a fragmentary marker and an absent referent. Thus, the connections and resonances that sonic traces produce disrupt national territorial logics of homogeneity and separation.
