Heikki Savolainen: Electromagnetic phenomena at the Bosnian Pyramids

Heikki Savolained, sound engineer, presents information on his research at the Bosnian Pyramids. By taking measurements with electromagnetic sensors he presents his findings. This electromagnetic phenomena is related to meditation.

SBResearch: About Archaeoacoustics

International archaeoacoustics collaborative effort, SBResearch, present an introduction to what Archaeoacoustics really is and why it is worth exploring. They also talk about some of their methodologies, equipment, research and findings.

Heikki Savolainen presents some of his finding of electromagnetic phenomena in Macedonia. He has transposed the electromagnetic waves to soundwaves and showcases these sounds.

Are there differences in auralisation between the Hypogeum of Hal-Saflieni and a modern auditorium with the same RT60?

Some ancient structures have psychoacoustic effects on human brain which alter the brainwave frequency.

Our study aims to show that the differences between the acoustics of Hal-Saflieni and a modern auditorium are perceptible even though both sites may have the same reverb time. Listening tests will be designed and conducted for data collection. Population will be selected among mixed students from audio-related courses (expert listeners).

UPDATE

Listening tests have been conducted on an expert panel of 13 subjects. The subjects completed 10 trials of an ABX test. The samples were 30 second sine sweeps [(logarithmic) from 65 Hz to 130 Hz (1 octave as resonances were found in this region in other studies, eg: 110 Hz)] convoluted with the impulse responses of the Cathedral of St. Etienne and Hal-Saflieni hypogeum. The RT60 for St Etienne is 7.81s and Hal Saflieni is 7.78s.
