Ljudvågor och paranormala fenomen
"An investigation into the link between infrasound and the perception of apparitions was performed in the 14th Centurycellar beneath the Tourist Information Centre in Coventry.Based on the effect described in The Ghost in the Machine(Tandy and Lawrence 1998) details of individuals experienceswere recorded and an analysis performed to test for anyinfrasound present in the cellar. Infrasound was found to bepresent at the point at which individuals had reportedapparitional experiences at exactly the same frequency as that
predicted in the original paper."
"Enligt en grupp brittiska forskare kan infraljud skapa känslor som obehag, sorg och rädsla samt framkalla rysningar."
"Long tubes such as corridors are ideal places for standing waves especially if they are closed at both ends. The resonant frequency of oneperson’s body parts would also be different from another so standing wave resonances may affect one individual but not another"
" Lord and Wiseman played four contemporary pieces of live music, including some laced with infrasound, at a London concert hall and asked the audience to describe their reactions to the music. The audience did not know which pieces included infrasound, but 22 percent reported more unusual experiences when it was present in the music. Their unusual experiences included feeling uneasy or sorrowful, getting chills down the spine or nervous feelings of revulsion or fear."
"Infrasound is also produced by storms, seasonal winds and weather patterns and some types of earthquakes. Animals such as elephants also use infrasound to communicate over long distances or as weapons to repel foes."
