Ancient Architectural Acoustic Resonance Patterns and Regional Brain Activity Authors: Cook, Ian A.; Pajot, Sarah K.; Leuchter, Andrew F.Source: Time and Mind, Volume 1, Number 1, March 2008 , pp. 95-104(10)Publisher: Berg Publishers Abstract: Previous archaeoacoustic investigations of prehistoric, megalithic structures have identified acoustic resonances at frequencies of 95-120 Hz, particularly near 110-12 Hz, all representing pitches in the human vocal range. These chambers may have served as centers for social or spiritual events, and the resonances of the chamber cavities might have been intended to support human ritual chanting. We evaluated the possibility that tones at these frequencies might...
