Possible Asperger Sensitivity to Infrasound

Infrasound is sound waves below the normal range of human hearing. Infrasound is common in nature, but additionally the environment is flooded with manmade low and high frequency sound. You know those industrial strength subwoofers that cause some of us severe pain, anger, irritation, and the urge to run away? Those effects are real.

Natural sources of infrasound - many animals can detect these low frequency sounds; a few, such as elephants, can also generate infrasound. Humans can't HEAR these long wavelengths, but they do have effects on the human nervous system and organs.

"Oobleck" is the now famous non-Newtonian fluid composed of cornstarch and water. Shown here is the Oobleck "dance" produced by infrasound from a subwoofer. I'm not claiming that infrasound has the same effect on any part of the human body. I'm using the photo to show that infrasound, even though humans can't "hear" it, has a physical existence and is part of our environment, from both natural and manmade sources.
