Since the 1980s, research into aggregation sites has focused on the material dimension of the archaeological record and has thus led to an incomplete view of the prehistoric reality. Early communities chose sites for many reasons. In this article, we explore the possibility that something as immaterial in nature as the acoustics of the sites may have influenced the selective choices made by the prehistoric peoples who created and used rock art in these meeting places. Employing the Impulse Response (IR) methodology, we systematically analyze the acoustic properties of Cuevas de la Araña, an aggregation site in eastern Spain with Levantine rock art, and 16 satellite sites in its surroundings. The results indicate that the acoustics of La Araña could have been important for creating affective engagement through musical performances carried out during the production and use of rock art, as well as for the choice of the site as a meeting place for Levantine populations.
