The acoustics of Stonehenge
31 August 2010
Institute of Acoustics president Trevor Cox has described the measurement of the acoustics of the ancient stone circle at Stonehenge in Wiltshire, England. In his article, written for New Scientist magazine, he describes how a pair of colleagues went about modelling the acoustic impulse response of the site. After bursting a bunch of balloons at various points around the circle, and recording the SPL the two were able to create some interesting models of how the site might have sounded.
The process was repeated at a full-sized, complete replica of Stonehenge, built at Maryhill in Washington, where the pair were allowed to use more sophisticated source and recording equipment.
The video shows the results recorded at Maryhill, demonstrating the possible effect the standing stones might have had on the sound of a drum beat.
