A new interpretation of the Domus de Janas of Ossi emerged from the meeting held last Friday at the town's Ethnographic Museum, which hosted the archaeoacoustics conference “Domus de Janas” curated by Paolo Debertolis, president of the international research team Sbrg – Super Brain Research Group.

After more than fifteen years of experience and studies conducted on underground sites in Malta and northeastern Italy, in 2019 the research group began an instrumental analysis of the Domus de Janas, a UNESCO World Heritage Site . The conference demonstrated how these ancient funerary structures were not just burial sites, but environments with astonishing acoustic capabilities, capable of inducing altered states of consciousness. A significant example is the Domus de Janas of Noeddale, where analyses revealed the same resonant frequency with both male chanting and shamanic drumming, while the effect was less evident with launeddas. This frequency is almost identical to that found in the Maltese hypogeum, which seems to confirm shared knowledge between distant civilizations. In this context, those participating in the rituals could enter the side rooms, moving away from the operator who produced the sound: thus, immersed in the vibrations, they reached altered states of consciousness that favored contact with the world of their ancestors, buried not far away in other domus devoid of acoustic phenomena.

Through archaeoacoustic techniques combined with neurophysiology , it was illustrated how sounds – activated by the voice or by musical instruments – can generate particular resonances capable of modifying the state of consciousness .

A medical-anthropological research approach that, thanks also to the use of instruments such as the portable encephalograph, allows us to study the responses of the human brain within these sacred places.
