Altered Cortical And Subcortical Connectivity Because Of Infrasound Administered Close To The Hearing Threshold

First, infrasound propagates over huge distances via the Earth’s ambiance because of very low atmospheric absorption and of refractive ducting that enables propagation by means of multiple bounces between the Earth’s floor and the stratosphere. A second property that has acquired little consideration is the good penetration functionality of infrasound via solid matter – a property utilized in the design and fabrication of the system windscreens. Psychologist Richard Wiseman of the University of Hertfordshire suggests that the odd sensations that folks attribute to ghosts may be caused by infrasonic vibrations. Their research instructed that an infrasonic sign of 19 Hz may be liable for some ghost sightings...
