Listen to Infrasound Made Audible by Infrasound Lab, University of Hawaii

"At the Infrasound Laboratory of the University of Hawaii, we use very sensitive microphones to listen to low-frequency sounds in the atmosphere. These sounds, known as infrasound because they are too low in frequency to be audible to the human ear, can carry through the atmosphere for thousands of kilometers."

Brief audio samples are available of infrasound emanating from volcanic activity, earthquakes and storms. These have been compressed (speeded up) so that humans can hear frequencies below the human range. Samples are available on ISLA home page and under Infrasonic Zoo.

If anyone does access the audio samples, I would appreciate comments on reactions, if any, to specific samples. Infrasound generated by an Arenal Volcano provides several of the audio recordings.

Much of the research being done in infrasound is aimed at verification of the Comprehensive Nuclear-Test-Ban-Treaty. I'm trying to track down scientific work on manmade infrasound and its effects on the human body. Too many articles are repeats of old conspiracy stories to be useful.

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.
