Infrasound could be cause of many spooky moments...

Originally posted by Azred: Infrasonics is an incredibly under-noticed area of scientific study. Some evidence suggests that infrasound might also be able to induce hallucinations, as the vitreous humor in the eye is vibrated, in addition to the chills, nervousness, etc. often sensed. Unfortunately, it is also possible to induce breathing difficulties, coronary arrythmias, damage to internal organs, vomiting, and/or death with infrasound.

freaky...hmmm...can i somehow produce infrasound? wait, maybe i dont wanna know. dont wanna go around killing people on accident...

Combine infrasound with point and shoot sound and you could gaslight someone real good [img]smile.gif[/img]

Silly, there's no such thing as sound. Wha...?

It already exists; I saw it demonstrated on some military technology show some weeks ago. The two sonic projectors can be aimed at only one person in a group and that person will get an instant splitting headache, but I forget the frequencies they are using (probably a combination of 16000 Hz and 16002 Hz to generate interference patterns of 32000 Hz and 2Hz). A very useful and incapacitating non-lethal weapon with few negative side effects.
The technology required to do serious damage necessitates using the very low frequencies, but the problem is that infrasound is omnidirectional and there is no defense, as sound waves are simply compression waves that travel through solid matter.

Interestingly, elephants communicate with each other using infrasound and other evidence suggests that snakes sense potential meals and enemies with infrasound (vibrations in the ground) as well as body heat.

So it really does work when you go in ears firmly blocked. Hear nothing, imagine nothing
