"Ear Tones" in my opinion represent a small part of the larger subject of human and animal types of earthquake sensitivity. And as I have said before, I believe that only an organized research group could keep track of all of those phenomena.

I am glad to see that you are working on one part of the Ear Tone picture. I myself am not especially interested in Ear Tones and do not presently even have time to look into the Ear Tone evaluation approach which you are apparently using. But I am (slowly) doing some work on other parts of that picture such as links between Ear Tones (and other precursors and earthquake triggering processes) and the positions of the sun and the moon.

Happy Holidays to one and all.
