New research from the University of Helsinki reveals the unique acoustic properties of prehistoric rock painting sites in Finland, where echoes are created
A new study reveals that prehistoric rock paintings in Finland, dating from 5000-1500 BC, are located on cliffs with special acoustic properties. The scientists discovered that the vertical rock faces, which feature paintings of deer, human figures and boats, also serve as effective sound echo generators.
The researchers made acoustic measurements at rock painting sites using a specially built raft for recording in the summer or from ice bodies in the winter in the fjords of Finland. The measurements showed that the hunter-gatherers who swam in the lake and approached the sites had special sensory experiences, in which the voices sounded as if they were multiplied and coming from a hidden source behind the rocks.
According to archaeologist Rita Raineau: "There is no doubt that people in the past heard these echoes, and they may have experienced them as the voices of the figures painted on the rocks."
Using 5000D scans and acoustics analyses, the researchers created digital reconstructions of sites such as the Silivari rock. These simulations allow the public to experience the sounds and landscapes as they were about XNUMX years ago.
The role of reverberations in rituals and culture
According to ethnomusicologist Yulia Spinitskaya, "The sound reverberations were an essential part of the sensory experience of the rock painting sites. They contributed to the energy and activity of the ancient people in the cliff areas, and perhaps served as a way to communicate with the physical or superhuman reality."
The study provides an example of the significant role of reverberations in sound and music in ancient societies.
