Why Do Schumann Resonators Work?


Schumann Resonators are little boxes you plug into the wall that produce electromagnetic radiation tuned to 7.83 Hz. This is the frequency that the earth/atmosphere system “rings” at when the Earth is struck by lightning. It is also a common frequency your brain “ticks” at.

When employed in the listening room, many people claim it makes their audio sound better. If this is true, then what is the mechanism of action?

-Is it a matter of the resonator producing a more relaxed mental state?
-Does it help block or alter electromagnetic interference?
-Does it add its own electromagnetic interference to your system that just so happens to be pleasing?

I experimented with one recently and what I noticed is that it seemed to remove some of the high frequency nasties or what some might call “digital glare” (although digital glare can also show up in analog systems). When I made this observation, the resonator was placed right next to my power strip that my CD player, preamp and some other devices are plugged into.

My “proof” of the effect is that I could turn the volume up louder than usual without it sounding “too loud.” The sound levels of the system weren’t any quieter, it’s just that the digital glare was reduced so that I could go louder before thinking “this is too loud,” which usually isn’t a sound level thing per se but the point as which some frequency (often the highs) become irritating.

So who here has experience with these devices? Do you like them? Does anyone know why they work?

A gold star for best question of the week. ⭐️ I’ve always wondered about that myself. I don’t know the answer but I do it anyway. Is that wrong? I also read the SR resonance devices sound better when they are physically isolated. And I do that too, isolate them down to about 1 Hz. Yet I’ve never really done an AB test. Am I just a lost sheep following other lost sheep? 🐑 🐑 🐑 🐑 At the same time it’s relatively easy to see how extremely low seismic vibrations in the range 0-20 Hz almost certainly would have an effect on something that operates at 7.83 Hz. Since everything sounds fabulous I assume I’m on the right choo choo train 🚂 But it does raise the issue of how can physical vibrations affect an electronic signal - I.e., electromagnetic wave. 🤔
So, over on another site they are also discussing Schumann Resonators. One poster suggested a vendor called Kelly Research Technologies that offers two types of units, a "Relax" unit tuned to "Low Alpha Wave (7.83 Hz) Schumann Earth Resonance Frequency" and a "Sleep Tone" unit tuned to "Delta Wave (4.0 Hz)."

One comment in their literature was interesting to this discussion;
Each unit is design to impact approximately 10 feet (3 meters) in any direction, with greatest effect nearest the unit.
Is this common for the other on-line units discussed here? Does the $300 Acoustic Revive unit provide a greater area of influence? Could this limited affected area account for some here not noticing the effects of these units? Would I need four units to cover a 20 x 19 room or would one unit near the listening chair be sufficient?

I also noticed the units can be powered by a 9v DC power supply connected by a 5.5 mm barrel connector. I may have finally found a use for my unused HD PLEX power supply.
To follow-up from below, how come none of the other vendors I have seen (except for Kelly Research) post anything about the effective area covered by their Schumann resonator products, or is this like fuse directionality.....you just keep moving it further away until it doesn't work any more....or closer until it does?

>>>>>Uh, noone here has reported he couldn’t hear the effects of the Schumann units. As far as I know there are only two of us who have them.

Best strategy for success. Start with one SR device and set it up optimally. Go from there. Your own results are the only ones that matter. The original Acoustic Revive device might have been $300 but the latest version is $700. Ouch! By contrast, my black usb doodads are $50 each. You can go crazy on a budget. 🤪
