Experiment: I purchased a Duravox (spelling) underwater speaker, bought a cheap $17 amplifier off ebay, loaded a "432 & 528 hz healing" video on the computer and dropped the speaker into the "cast iron claw foot bath tub" I inherited from my Grandmother.. Crawled into the hot water and I could feel the tingle from the music reverberating in the "solid iron tub". Other side of the stereo feed was to a audio shelf speaker. This is the sound track off youtube I used.. [url]
I hurt my back in 1988, have had no feeling in my feet since. I got out of the tub a hour later and had feelings in my feet.. what else it did to me? I felt invigorated, energetic, I am hypo-thyroid and my dosage has never been exactly right, low testosterone, overweight (and ugly)... I feel bad a lot, am grumpy. Was in Martial arts training before the injury & health issues and felt the "chi" you build before a "board break.. this is similar". My wife had positive results, suggested I buy another amplifier to use just for this purpose. She was "flushed and stayed in the tub for near a hour". (as I did, till the water got cold) She also had trouble calming down to go to sleep that night.
This so far has been a success, why?
(1) I suspect the cast iron tub is better than a fiberglass jacuzzi.. I think the iron tub is a resonance chamber.
(2) I suspect the water achieves a change becoming charged like in a Tibetan singing bowl.
(3) I suspect I wanted it to work, a placebo effect. I can play the video on speakers and recharged slightly, thou I do not feel as good as when immersed in the vibrating water.
I wish I could fully immerse in the tub, My knees, chest & head all stick way above the water line.
I tried once before to stimulate the "chi aura", using a tesla coil, a motorized driver to pulse a insulated platform, and LED glasses to synchronize my brain to the pulse.. It did not work other than making my skin crawl like I had bugs all over me.. I didn't suffer ill effects, or die.. yet.. But that was a failure in my recollection.
