However, many people wish to believe in ghosts. If ghosts do exist and can produce low frequency waves, couldn't that disrupt electical devices, cause illusions (of any sense, not just sight) among other things? If someone knows more about this kind of topic start a thread. That'd be interesting!  |
I found this on the web when I did my google search:
Quote: | Research has previously proven that exposure to low frequency sound can cause a variety of physiological effects, many of them adverse ones, such as shivering, anxiety and breathlessness. These responses can lead a person to think that some unseen danger is imminent, or feel like he is being watched. Infrasound might even cause hallucinations. Tests at 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 these conditions, there would be a "smearing of vision" that is capable of making someone see evanescent hallucinations in the periphery of their visual field. This effect is reminiscent of the theories of neurologist Michael Persinger, who has suggested that electromagnetic waves can interfere with brain activity and lead people to think they see ghosts or aliens. |
