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.

A Link to Basic Genetics and Environment

Both Environment and Genetic Makeup Influence Behavior

Good grief!Advice on dealing with sensory sensitivity? Have your Asperger child wear earmuffs to dampen noises that cause distress. Better stock up - you'll need these for a lifetime of environmentally induced pain!

A characteristic common to many Asperger individuals is sensory sensitivity. The link above goes to a clear and simple discussion on how genetic make up and the environment affect animal behavior. It's a good place to begin understanding our sensory differences.

Although these sensory sensitivities are noted in articles on Asperger symptoms, there is little apparent interest in research on the actual source and nature of these noteworthy physical experiences, which Asperger individuals frequently describe. Instead, these differences are commonly written off as defects in the Asberger brain, an astounding attribution that like too many assumptions about Asperger symptoms is accepted merely on repetition.
