Regarding #2 - there's people reporting one ear then both ears then the other ear in about a 15-30 second span. So a six hour span is not always seen. Have you made attempts to determine the % of time this happens ? It may be an exception possibly or occur at low frequency/intervals...

Regarding #3 - This may just be an example of high frequency noise (and nothing significant in this regard). Have you ever identified the exact frequency ? If it's above 16-20k Hz then it's probably like a "dog whistle"...some can hear it (usually younger uncontaminated ears) and some can't (do to noise pollution hearing loss with age, etc.).

Regarding the "research group" - it appears the folks on this board "are it"....(though JOB/Will's Syzygy board is also a testing / experimenting ground for this type of info. as well...with informal cross checking going on as well as Mary Maya's site)

I believe your data on the freeweb site may have some hope for proving useful...so keep plugging away....

The article on cell sensitiviy to voltage changes really opens up the entire human body to all processes Possibly being subjected to changes as a result of being exposed to a varying voltage fields

Some exotic body change reports I've read (and assigned by senssitive as possibly pre-eq. related) are:
1) Headaches - that move around the brain
2) Shoulder - pains
3) right side/left side tingling feeling
4) angina / heart changes
5) ear tones
6) dizziness / vertigo
7) cramps, etc.
8) face/ ear twitches
9) (Lots of other stuff too).

Anyway...it's no wonder that a geologist / seismologist would be hesitant to ever approach this angle of attack. This type of study is something a doctor or sociologist would be more prone to get involved in.... Also, there could be "lots of noise" to sift to get to any "signal".

The first step, is getting folks who are sensitive to diligently start logging their symptoms (and not try to correlate to eqs initially) with attempts to correlate to eqs mapped in a second log.

Obviously, if the person starts to learn a "sound" (or other symptom) as has been speculated then this would be useful information.

Science would demand a statistically long period of data gathering in order to get enough samples in order to gain "confidence" in the (significant) results (if any).

Since different people perceive things differently (sometimes it seems) each person should also write a library of sounds that they hear (much like Mary Maya has done at her web-site). This allows investigators to try and cross-link different special "sounds" heard by two or more "sensitives".

Anyway, it looks like your data page is a good effort at trying to capture the data. More details about your signal could be useful though....
