Schumann Resonator reviewed

Remember I experimented with a Schumann resonator some time ago? That was in January 2011, almost a year ago! Well, I didn’t do much with it, except built a few for friends and customers to “play” with. ¬†One of those Schumanns I sent to a friend and later… he reviewed it for the local paper – If the Schu fits.

Suddenly, I got this deluge of emails! Many questions, many requests… The timing is kind of off as I don’t happen to have any unit at the moment (except the one permanently residing in the bedroom). The timing is off as I’m busy prototyping a new DAC which is very very interesting…

Anyway, feel free to read the review and the article on my site, both linked above. My Schumann article also references the 6moons review where the Acoustic Revive’s version is the subject of the review. The idea of bifilar windings on the PCB I got from the AR version.

Not surprisingly, there is a clone of my design! It’s built exactly the same, same PCB layout, same circuit… the only difference is that their PCB has 4 mounting holes while mine has 2. These guys even have the cheek to advertise it for sale.

Hey, 7.83Hz isn’t that difficult. Can’t think of other circuits?

    I ordered one of your Schumann Resonator circuit boards and built a unit. It’s in a simple grey plastic enclosure. I placed the unit in the far end of the bedroom (relative to where are heads rest in sleeping position), under a dresser. I did not tell my wife about the unit, as I would run it for two weeks, then find out if she noticed a difference. I noticed an improvement in my sleeping in that my wife’s random snoring/noisy breathing was apparently lessened, or at least my perception of it. When I told her about the resonator, she complained that she had slept poorly during those two weeks and was constantly feeling tired. So, the unit is now off.

    Given your comments about adding the two 100 Ohm resistors to reduce the input, I am curious to know you thoughts about what resistor values I might try to reduce the input a bit more? 150 Ohms? 200? Should I use variable resistors/trim pots? What instrument would I use if I wanted to measure the output from a wave perspective?

    Your thoughts would be appreciated. Regards,


    Merry Christmas and Happy New Year to all!

    hi david

    you don’t have to do that!

    the easiest way to reduce the power is to place the resonator further.

    in my home, with the resonator near my feet, my wife and i couldn’t sleep at all.

    placed 3 feet away, she could sleep better though it doesn’t have much effect on me.

    so experiment with placement.

    as for resistors, you could go by doubling the resistor values each time you mod but it’s too much work.

    placing the resonator further is much much easier.
