Infrasound and It's Effects on the Human Body

by Jim Hale

It has been suggested that low frequency sound waves known as infrasound can create cold chills, a sense of paranoia and distress, and even hallucinatory figures glimpsed in peripheral vision. Infrasound tests conducted by NASA have shown that the human eyeball has a resonant frequency of 18 cycles a second, and will vibrate in sympathy with infrasound waves that have a similar frequency. Under such conditions, a person might experience a “smearing of vision” that could result in evanescent hallucinations in the periphery of their visual field. This effect is reminiscent of the theories of neurologist Michael Persinger (see more below), who has suggested that electromagnetic waves can interfere with brain activity and lead people to think they see ghosts or aliens.

Putting the theory to the test

The VGHRS Audio/EVP expert Jim Hale has devised an instrument to measure infrasound. The instrument uses a commercial seismograph transducer that converts low frequency vibrations into an electrical signal. This electrical signal is amplified and fed into an oscilloscope which provides a visual display of the waveform thus revealing its frequency and relative amplitude. The VGHRS has used this infrasound instrument in an investigation of the Byrd Theatre in Richmond, VA. During the course of the investigation, Jim Hale experienced several “kicks” to the back of his seat in the theatre when no one was around. Notably, infrasonic waves were registered on the oscilloscope for each “kick”—perhaps indicating that infrasound may be responsible for more than just hallucinations and “creepy” sensations. The VGHRS will continue to test for infrasound at future investigations as possible to collect more data.
