90 hz emerged in response to a study of the acoustics of the King’s Chamber which lies at the core of the Great Pyramid at Giza. Recent tests have classified the space to naturally resonate at 90 hz, believed to be activated by the subtle movement of air through ventilation shafts. Represented at the 1:4 scale, 90 hz is an aural model of the King’s Chamber that materializes the deep void as a solid. Buried within the compressed dirt lies a loudspeaker, resiliently transducing the resonant room mode of the actual chamber to be felt within the space of the gallery.
