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?

No need to apologize mahgister, especially not when so rudely insulted by jerryg123 who is after all only jumping to conclusions.

I tried three times to start a discussion about how it is that we learn to hear things we are not accustomed to hearing. A few really are interested but it seems a lot more are offended to think they are not already the last word in listening skills and so they made like jerryg123 here throwing insults instead of trying to maybe learn something new.

Most everyone is able to hear volume. If the claim is one is louder than another pretty much everyone is able to judge. Frequency response is really just volume, but now it gets a little bit harder because we are trying to judge volume not just overall but at different frequencies. This takes a bit of practice but eventually a lot of us are able to do it.

From here on out though it gets a lot harder- and fast. Lots of things resonate and this alters frequency response but in a more subtle harder to discern kind of way. All instruments and voices have their own resonances, as do rooms and microphones, etc, and this all makes it a real challenge to differentiate and discern what is doing what. Awful lot of audiophiles never do get this one down. It is shocking how much of this resonant coloration there is, but maybe not so shocking in light of how few audiophiles are even aware it is going on. 

We haven't even gotten to how we learn to listen for these things, still just putting labels on a few of them.

One of these someone was asking about recently is grain. Grain is a little harder to describe. Nothing changes in terms of tone or frequency response, the sound just gets a little bit smoother and more natural when there is less grain. Most all components have a lot more grain when new or cold than after burning in or warming up. So one way to learn to hear grain is learn to hear the difference between your amp (DAC, phono stage, etc) when cold vs some hours later. 

Part of what I hear with SG is a reduction in grain. 

Another one is hash or grunge or noise floor, whatever you want to call it. This one is probably some combination of RFI and EMI, but who knows? Doesn't matter. What it is, that is a different subject. One thing audiophiles are good at, switching subjects. Real serious obstacle to learning. Ditch it. Back to the subject: how this, whatever we call it, sounds.

Here the simplest test is to turn off some circuit breakers. Do this and you will hear a noticeable reduction in hash or grunge, a blacker background, with more air around images. 

Part of what I hear with SG is a reduction in grunge, a bit blacker background, and a bit more palpable imaging. 

I would not say the improvement is huge. To me it is obvious, but then I am an exceptionally discerning listener. Sorry if my being good offends those who are not, but this is in no way a zero sum game. Nothing will make me happier than you read and learn and become a better listener than me. Because I want a better system. If you can hear things I can't I want to know about it, so I can maybe learn and become better myself.

Now that we have us some labels, to put SG in perspective, I would say the 9 I have makes an improvement roughly about as good as the improvement in my system from when it is first turned on to how much better it is an hour or so later. That is all. For me that is more than enough to justify the $90 they cost me. 

If for you it is not, oh well. 

Between Chuxpona and Chuctoberfest we have had personal direct experience with a number of audiophiles. Some of them frankly admit to not being able to hear things that are obvious to others. This goes both ways. I am supposedly deaf to gross harmonic defects. Whatever. Would like to know what that is all about. Which notice, is a completely different response than calling the other guy names.
Interesting remark about "grain" that correspond to my experience with my 12 S.G. connected  grid...

Thanks millercarbon...

Myself though i think information is better transmitted to a more " frienship" way when being in a relation...



My best to you....
@millercarbon. You have issues with reading comprehension. As I stated I have tried all your silly crap, Sticks, Generators, Rock, Crystals….. And none of that voodoo is real.

You are a charlatan and shill and full of carp. Go push some mediocre gear and speakers and then spent $10 k on rocks and crystals.

I get why you are so loved around here.

You truly are a despicable shill.

Later Chuck you make me 🤮 

@jerry

When we speak rudely about @millercarbon -- or anyone in here for that matter --  we may offend half the room, mon frere. 

Look up Dither. 

Also remember that the scientific community called Vitamin C a "witch doctor" cure for scurvy for nearly 200 years. 

Here is what the Romans used to say, every day, to make people like you go away:
