Abstract
An archaeoacoustic study was recently conducted within the prehistoric cave system of El Castillo in northern Spain.
With findings dating back at least 40800 years, archaeological studies of this cave have revealed the presence of
prehistoric ritual activity associated with early shamanism. Simulated audio tones of varying frequencies were created
and emitted from the location at which it is thought the shamans would conduct rituals within El Castillo, while the
sound was simultaneously recorded from the likely location of potential observers or participants.
