Schumann Resonator

@mahgister- I am not opinionated at all.

Remembering your past posts i think you are right...

I apologize to you if i answered sometimes in a too direct or passionnate way....

I cannot answer to all your questions " why"....

I did not begin forme  as a  scientific inquiry.... I just try 2 years ago to replicate what Acoustic Revive customers reported about their costly purchase with cheap modified chinese one thats all...

Like i said anyway, even if these devices work with an audible positive s.q. effect for me and for many others, i did not recommend that for first acoustic tool at all...or in replacement of more powerful others like Helmholtz pipies and tubes resonators...

But anyway 2 for 20 bucks is only a fun experiment to try for those who "dare to go where no one ever goes  to go before ".... 😊

  It is not a participation in mass murders nor in a Ponzy scheme....

I am like you at the end, some experiments appeal to me, some others dont....

My deepest respect for you and regards....

OK:

I've played around with this "unit" for the past Two days...

https://www.amazon.com/Generator-Ultra-Low-Frequency-Rechargeable-Screwdriver/dp/B07NP3ZGZK/ref=sr_1...=

Yesterday, I placed it a few feet from my head while reading in bed and kept dozing off having odd/short dreams that I remembered upon awakening.

Usually I do not have dreams (or I do not remember them if I do have them) and I am an exceedingly light sleeper waking up constantly to reposition my body due to common aches and pains for someone my age who was rambunctious/accident prone in earlier life.

So, this was my first immediately recognizable effect of the device.

I also noticed that (while awake) my stomach started to churn/gurgle after 10-15 minutes of being in close proximity to the device.

In addition I noticed that instead of the unit relaxing me I ended up clamping my jaw (not a good thing) and I also failed @ doing my usual breathing/relaxation exercises which usually cut my old aches and pains (migraines aside) by 90%+.

Today I played around with the device while watching a recording of Clapton's Crossroads 2019 video on a 20" Samsung flat screen TV located on a blanket chest @ the foot of the bed.

The TV (placed mid-room without a wall behind it) has a reflection screen, slightly larger than the size of the TV, mounted a few inches off the back to help duplicate close to wall mounting.

If I placed the face of the device (handheld) towards the TV the sound became distant with decreased dynamics/detail - colder and thin is a good descriptor.

When I reversed it directing the face of the device towards me the sound became fuller and louder with increased detail and dynamics, like it was sucking the music towards me.

The changes were easily heard and repeatable.

I suggest that anyone experimenting with this tech first try what I did, due to the simplicity of doing so.

Not keen on the clenching jaw effect as well as it seeming to interfere with my daily bio-feedback/self hypnosis/meditation (whatever you want to call it) excercises.

Just saying that with this particular unit the changes in (TV) sound were extremely apparent.

Assume that it would be a PITA to adjust/align them with the main HiFi setup, but "this unit" definitely altered the perceived sound as mentioned.

Thanks dekay....

Interesting... It could have adverse effect on electro sensible people...It seems in your case...For me no ill effects with 12 in my room 12 hours a day....It is interesting to know tough for some sensible people...
😁 My only effect is the audible upgrade.... I am lucky.... 😊


I never try the battery one, thinking it was less practical than the USB one for me but i am not sure if i read the descriptor the battery seems to be long life, i will try one or 2 this summer...

My best to you...

@mahgister- this is all for fun, and if it weren’t for these weird reported physiological effects, I might’ve tried the SGs out. I’ve learned a lot on AG and improved my system tremendously, sometimes very inexpensively, others little chunks here and there. I really never knew that so many people spend so much $$ on stereo equipment and are so seriously committed to it. I try to get the best bang for my buck just for the sound, not the looks or to impress anyone but me. I used to think $25K for a stereo was a lot of money, now I think I am a beginner after 40+ years with a low 5 figure (barely) investment. Some are spending 6 figures without a second thought. It must be nice.....
@Dekay - WOW. Maybe it interfered with the tv signal? Did you try to see if it changed the sound on your stereo? There is no signal to interfere with over the air there.

7 years ago i begins my search for audiophile experience...

At this time i was impressed by gear of very costly price....

Now after all my peanuts costs experiments for 2 years, i smile and dont look at any of them, with envy at all; for sure they are better than mine...

But like i said if the harpsichord or the orchestra fill the room, all that for 500 bucks and my homemade controls device, I dont need anything more....

The law in audiophile experience is this one: Dont upgrade anything but instead embed everything rightfully in his three working dimensions...

An Helmholtz grid cost nothing to make and is more powerful than any upgrade...And it is pure known acoustic science... Unlike the S.G. grid which work but who knows why... And the Helmholtz grid is way more powerful in his own way...With Helmholtz grid the room is ACTIVATED and is no more a set of passive bouncing walls for the sound coming from the speakers...The room is active now and transform the speakers sound, no more only passively, by absorbtion, reflection or diffusion on his surface but by acting like a complex heterogenuous set of pressurized engines....

No reviewers call for that.... No reviewers has ever explain that.... At best they want to sell costly "secondary addition" to a system called "tweaks"...My embeddings controls are NOT secondary addition at all, they transform any system and make it able to give his best....

Acoustic science says it , speakers cannot beat their room....


I look now to refine my actual results not to spend more money....I listen my music not so more the sound....

But anyway i know first hand that most people have no idea how to work with their room and gear....And sometimes dont have a room to play with like mine.... I have no clues myself like most few years ago reading all audio magazines about upgrades for me...It was my desire for a good sound without the money that drived me here... Thanks to my limited purse, i was in the obligation to be crazily creative... 😊


It is simple...

I am only here to motivate a few.... If i can help..... Others with money dont need my inconvenient and blasphemous "truth"....



My deepest respect and regards....
