The acoustics of the Lower Chuya River area rock art landscape are analyzed through both the exploration of its acoustic properties and the ethnographic information gathered about the region. The results obtained in the acoustics tests undertaken in the area, in particular at the rock art sites of Kalbak-Tash I, Kalbak-Tash II, and Adyr-Kan, are examined. They indicate that the perceived loudness resulting from a natural amplification of sound (strength parameter) and music and speech clarity may have been some of the reasons behind the selection of these locations for rock art production. The ethnographic sources related to the Altai and other Siberian areas are then reviewed as a way of providing an ontological framework for the study of Altaian sonic concepts and behaviors in nature. As the sources indicate, at least for the historical period and presumably earlier, in the prehistoric period, all existing beings are entangled by sound, and they mimic each other in endless ways. We argue that these sites were selected in a non-linear relational ontological framework. It is suggested that the multidisciplinary perspective combining archaeology, physical acoustics, and ethnography has considerable potential for providing a new, richer understanding of rock art landscapes.
