From a 2013 PCAS presentation by Dr. Steve Waller. He studies auditory phenomena in archaeological sites.

Another auditory illusion is attributed to interference theory. This occurs when sound waves from two sources cancel each other out. People walking in a circle around two identical sounds will pass through areas where the sound is less audible, suggesting a barrier between the source and the listener. Dr. Waller told of testing this theory by blindfolding subjects and having them walk around the two sources in an open field. He then had the subjects draw the scene as they perceived it. In all cases they drew high solid walls, pillars, or rocks at intervals around the circle. Dr. Waller suggests that the English stone circles – such as Stonehenge – may have been built to replicate this audible pattern, that visual shadows equal the acoustic shadows and mimic the interference patterns. Mythology of the region refers to two magical pipers who played to entice maidens who danced around them in a circle and were turned to stone.
