Acoustic resonance discovered at ancient megalithic sites. West Kennet long barrow sound travels 666 ft without losing decibel to short barrow Stonehenge structure amplifies sound and produces infrasound effects around 14 Hz Hypogeum in Malta has perfect acoustics where Greeks paid to sleep for answers
Research reveals ancient megalithic sites created intentional acoustic effects. Acoustic studies of West Kennet long barrow show its stone chambers resonate at frequencies that are a 'perfect fourth' apart (4:3 ratio). Research on Stonehenge has examined its acoustic properties and suggests the prehistoric site may have been used for exclusive ceremonies. Malta's Hypogeum has been studied for its acoustic qualities, with chambers sustaining strong resonance between 95 and 120 hertz, within human vocal range. These sites utilized resonant frequencies within human vocal ranges. Further research is needed on acoustic properties of ancient structures.
