Archaeoacoustic Analysis of the Hal Saflieni Hypogeum in Malta

A recent archaeoacoustic analysis of the Ħal Saflieni Hypogeum in Malta revealed strong resonance effects, with double resonance frequencies at 70Hz and 114Hz detected in the 'Oracle Room.' These frequencies, when stimulated by male voices or percussion instruments, create a phenomenon that affects human brain activity. The hypogeum's unique design, described as 'architecture in the negative,' mirrors megalithic temples above ground and was likely used for Neolithic rituals. Laboratory testing confirmed the impact of these frequencies on cognitive processes, suggesting they supported social or spiritual events in this prehistoric complex.
