Hi Mike,

I'm ROFL! One unfortunate thing about ear tones, or Mother Nature, they only arrive on their schedule, not ours, same as earthquakes.

Ear tones last as short as a half second or up to perhaps a minute. This is what makes it difficult to put a pot over ones head or get sheilding equipment in place. Its over before you get there.

But get this. Up at Mammoth, at Lake Mary there's a scientist who created a piece of equipment to measure C02. Its a teflon frying pan. Inside it has a little fan and when used the pan is turned upside down. A motor on top runs the fan and takes the reading. It was replaced by a fancy piece of equipment which cost $100,000. Its huge. It works, but not as well as the frying pan, so says the scientist. Cool huh?

I'm still trying to find out at what frequency dogs can hear a dog calling whistle and also at what frequency mice can hear rocks break in a lab. I want to know if its possible I can hear the same as they do and if not, why not, and at what frequency I do hear these things. Theres more questions than answers today. However, that's what makes research, research. Observing, testing and learning until valid results are obtained and then it becomes as I have written, "My Seismic Sounds Theory." IE: "Earthquakes do not arrive unexpectedly because they are preceded by a sound from the fault in question." Needs some work.

So Michael, I can tell you all of the parameters needed to describe a precursory earthquake tone. I've got the list.
