Is Sound Creating Crop Circles? (cont.)
By Freddy Silva
Jenny also provided a physical connection to the creation of crop circles I’d been looking for, since many of the vibrational patterns captured in his photos mimic their designs. Some are blatant imitations, such as the circle surrounded by concentric rings typical of early 1980s patterns; the tetrahedron at Barbury Castle in 1991; even the highly structured star fractals of 1997. Visually there is little room to deny the connection. But what evidence links sound and crop circles at a physical level?
Many accounts exist of a trilling sound heard by people prior to witnessing crop circles forming. The reports describe a sudden stillness in the morning air followed by a trilling sound and the banging together of wheat heads, despite an absence of wind. A whole section of crop then lays down in spiral fashion, the whole episode lasting less than fifteen seconds. Interestingly, the Aborigines relate to this trilling sound: during their ceremonies to contact the sky spirits, a specially-shaped piece of wood called ‘bora’ is attached to the end of a long string and whirled, creating a noise practically identical to the crop circle hum. It was later discovered that not only have crop circles appeared in Australia but their manifestation figures in Aboriginal lore, just as crop circle geometries appear in Aboriginal rock paintings.
This crop circle sound was captured on several occasions on magnetic tape, notably by the BBC whilst recording an interview inside a crop circle, whereupon the noise rendered a £30,000 TV camera obsolete. Since this sound has the ability to transmit on radio frequencies and interfere with electronic equipment, birds and insects can be ruled out; and although skeptics are quick to accuse that the recorded sound is, in fact, the grasshopper warbler, stroboscopic analysis of both voice prints reveal vast differences between this bird and the bizarre noise. Besides, such birds frequent marshes, not vast, open fields of cereal crop. Subsequent analysis of the trilling noise at Sussex University and NASA's Jet Propulsion Laboratory concluded the noise was mechanical in nature and vibrating at a frequency of 5.0-5.2 kHz.
This revelation took me on an extraordinary journey of connections. Back in the 1950’s agricultural researcher George Smith found that exposing corn to sound frequencies produced a higher heat content in soil, as well as a slight burnt appearance in the plants. Such effects are consistent with the slight 'baking' regularly observed in the soil of crop circles, where the affected area appears noticeably drier than the rest of the field despite overnight rain; the same applies to the 'slight burning' at the base of crop circle stalks.
