Hi All,

Before we get into infrasound I wanted to mention that Saturday night I had an ear tone type of event that was totally new and I'm hoping someone out there may know what this is all about and if so, please post it.

I experienced an actually feeling of vibration in my right ear radiating into my face near my ear and I heard a humming sound that lasted for ten seconds. It was entirely different that the traditional ear tone where one has a sense of a sound moving. It was more stationary. So I don't really know what that was all about, so I can't say it is earthquake related and if it is I wouldn't know whether it was a local event or one 375 miles away. But frankly, I didn't like it. It seemed like it was a bad thing. Who knows, maybe someone in the neighborhood has some kind of wave equipment?? Maybe I should call it the Santa Rosa Hum.

Well, here's another thought about what the source for ear tones might be...Infrasound. Here's a segment from one article with the link and the second is in the box below.

Ultralow pitch earthquake sounds are keenly felt by animals and sensitive humans. Quakes occur in distinct stages. Long before the final breaking release of built up earth tensions, there are numerous and succinct precursory shocks. Deep shocks produce strong infrasonic impulses up to the surface, the result of massive heaving ground strata. Certain animals (fish) actually can hear infrasonic precursors. Precursory shocks are silent, being inaudible in humans. Animals, however, react strongly to the sudden surface assault of infrasonic shocks by attempting escape from the area. Animals cannot locate the source and center of these infrasonic impulses, behaving in a pitiful display of circular frenzies. The careening motion of wild horses and other domestic animals indicates their fear and anxiety. Poor creatures, neither they nor we can escape the infrasonic source. Encounters with natural infrasound reveal their vast extent, covering hundreds of square miles of surface area.
