Yes good idea frogman. Let’s censure everything we disagree with or do not like. That will get us far.
Schumann Resonator
I got 2 of these from Amazon...careful that free returns are applicable. I charged them up, turned them on and holy moly.....they do help with my system. What I hear is clarity....space between instruments, a definite difference in upright and electric bass, wider soundstage...you know...all the good stuff. At first I thought it might be increased brightness, but no....it is still the same in that regard. I still can't believe it, and will listen again tomorrow (saved the packaging for the return)...but today, I'm about to keep them.

We all know that throughout the history of HE audio there have been examples of things or ideas that many considered to be implausible or even quackery at first and which later turned out to have validity. If only there were some type of filter that would prevent someone from opining on the validity of something that he/she has not tried 🤔. There doesn’t have to be agreement; simply first hand experience. Perhaps a suspension of ability to post for a certain period of time? Say, no posting for a week for each “infraction”? 😊 |
Interesting thread, even if just for the entertainment value. I have no doubt, as with many things audio, many people get a different response from their system/ear/brain interface. Real question: It would seem to me as with all waves that there is the distinct possibility if using more than one SG that waves will peak and trough at different points in a listening room. There must be phase distortion? So, I'm thinking one does whatever it does, but two or more would tend to disable the whole. Maybe because the wavelength is so long at that freq its simply inconsequential? Regards, barts. |
I use mu-metal foil to shield my low level phono step up transformer from noise from nearby HVAC equipment. Nothing special there, transformers emit em radiation that can induct undesirable noise into electric circuits. That's basic electronics. Thing is I read that the theory behind benefits of Schumann is pretty much entirely based on its effects on humans as part of the earth's environment. Nothing about its effects on electric circuits or that being a good thing. Just saying. IT's an interesting theory, but again not a hard one to test and support or not. Like a transformer, close unshielded proximity to an electric circuit should have a greater effect than farther away , and there is always some range limit involved. |
Yes thanks for that we know people are free to buy whatever they want. Imagine if NASA relied on incomplete data or hearsay to land that rover rather than understanding every detail of what was involved to make it work to the nth degree. I know people are not NASA. But some are engineers or technical people or scientists who actually care about how and why things work including their hifis and use that to make informed decisions and others benefit from that. That includes me. It’s all good. Buy away! If some one can tell me the right way to use the device rather than leave it to chance, hearsay or theory, I might even give it a go. |
@mapman - LOTS of audio companies mess with the electromagnetic field in their products. It's not just amps but anywhere an audio signal is present. The most obvious is the transformer because of the amount of electromagnetic fields that are present there. And yes they can be manipulated to give better sound. |
No argument there. Just clarifying that it is not the sound waves themselves that can be affected...only the electric signal used to create them...or the person listening. Both are possible and not mutually exclusive. If you muck with the electric circuit, anything is possible...good or bad... So you are saying placing the device closer to your amp produces better sound? Is that how it works? |
Yes and amp designers go to great length to minimize or totally eliminate that particular effect on the electric circuit. Its an interesting theory about how the device works its magic. First time I heard it. Not hard to test. Proximity of the device to the amp should produce better sound. Its a small inexpensive device. What is it’s range? If it works that way you should let the vender know if not already in the manual so they can inform all users how to best apply their product. |
Ok well then by that logic the best place for the device is on or close to your amp. Is that in the instructions? Please try it and report the results. Just to keep the facts straight, the magnet does NOT ineract with the sound. It interacts with the electric circuit in the amp which in that case is likely to have a detrimental effect on the sound if audible. |

@bemused The problem with your theory is the device is emitting an EM wave not a sound wave. How can that interact with sound? There is definitely nothing to hear in an em wave. Two different things. Does the light you see or long wavelength radio waves emitted affect the sound? The answer if there is one seems to be that if an em wave interacts with anything to produce an effect either positive or negative it is the person and not the sound waves. That is at least the prime theory of how Schumann frequency has an effect on humans and there is little in the literature I can find to firmly support even that outside of marketing material. Maybe we expert audiophiles here with the golden ears can solve this problem in physics and strike up a big win for all.... |
bemused is exactly right. Like I said before, this is nothing new. I've been using ElectroClears in my system for at least 10 years. They labeled their products as using QRT technology. Nordost eventually bought the rights to QRT and have a number of products based on it. I think ADD-Powr is just another derivative of that technology. All of these things manipulate electromagnetic fields and the resonances they create. I really don't get people who don't understand this or think its "voodoo" After all, since we use Alternating Current (AC) the sole purpose of a transformer, for instance, is to change the magnetic field. The Schumann Resonance is just a naturally occurring change to the electromagnetic field. |
I enjoyed reading through most of this thread, especially the explanations posited concerning the earth's frequency and dither. Very entertaining. @bhvf I understand your frustration and lack of any response offering a rational explanation. @ps Ditto. I can tell you that I have been working in the area of resonance and resonators for a long time and it took a longer time to discover a rational explanation as to why the Schumann resonance devices work to affect audio systems and signals. The idea is not rocket science, in fact it's pretty elementary physics and electrical theory. The frequency must be a low em frequency. It can be as low as 8 Hz or even lower. Google ELF or ULF in the frequency spectrum. The frequency generated is a square wave. Not a sine wave. Joseph Fourier, the eminent 18th century physicist made the discovery that square waves are comprised of a series of harmonically related sine waves of various phases (cosines too) from the fundamental out to infinity. The good news is that as you sum the harmonics up the frequency band the amplitude of each subsequent frequency decreases in a logarithmic way. Every Schumann device that I am aware of, generates a square wave at 7 - 8 Hz or so. But the question is how does that affect audio signals? The answer lies in resonance. Just like a tuning fork, when the frequency of the fork comes into contact with another thing that has the same resonant frequency then that thing is going to vibrate or gain energy from the activating or stimulus energy signal. So, the low frequency square wave with its underlying sine wave harmonic structure interacts with complex audio signals comprised of sines and various wave forms that can possibly be described under the sun, mathematically (i.e. calculus). This interaction activates resonances throughout the audio spectrum depending on the activating or driving signal (Schumann) and the audio signal. There is more energy from the resonance happening at the lower frequencies than at the higher frequencies due to the higher amplitude of the early harmonics. Less energy at higher frequencies also assures a more musical affect. The energy change can be easily measured with a sound level dB meter aimed at the speakers and can be seen on a scope or spectrum analyzer. To sum up, a low frequency square wave unleashes a harmonic series that when introduced into an audio system, interacts with like frequency signals,produces resonances or an increase in energy or amplitude of those audio signals. Greater S/N occurs along with increased dynamic range to the sound. Btw, there is a brand that promotes the idea and that is ADD-Powr. |
@oldhvymec it’s EM radiation at that frequency/wavelength, not sound. Nothing to hear and outside the frequency range your eyes can detect so you will never see it either. https://sites.google.com/a/coe.edu/principles-of-structural-chemistry/relationship-between-light-and... 7.83 Hz has a wavelength of about 38,000 kilometers which is WAAAY off to the right in this chart, well past EM wavelength of radio waves. |

The product info on Amazon is interesting. Reads like written in broken English. It says it does not emit sound. That would leave EMR as what is emitted by default. That is what the earths Schumann resonance is based on. So who knows? It’s a mystery. Try it and see if one must. It’s a good kibbutz that does not cost much at least. |
Scratch what I said above about the phase of the resonator interacting with the earths natural Schumann resonance. That refers to a EMR frequency. Sound also has frequency and wavelength but is a different kind of wave (sound) altogether. I’m assuming these devices emit sound waves at the Schumann frequency not electro magnetic radiation EMR. In either case however the device is the source of whatever it is that it may emit so one would expect the results to vary significantly with distance from transmitter ie the device to the sensor ie the brain and ears. |
This discussion is priceless. Everyone is entitled to their opinion. If you think it makes your system sound better, then it does. Foreign governments tortured hotel guest with inaudible sound waves that got headaches and got physically sick not knowing why. Perhaps this has the opposite effect as people are reporting. Maybe try drinking a glass of champagne before listening. Bet it makes the stereo sound better..... |
LOL You sound like me, I asked a lot of questions. too.. I use 2, I'm not droolin' any worse than before.. Orange hair count for anything? :-) My rabbits ears (Junior) lay down when they are on.. is that saying something?. Yup his ears lay down, he is a funny bunny, likes USA blues too, BIG BB King fan. junior the rabbit.. Dog not so much.. She just like to dance, around the hat... Regards |
Just saying. I know you are too open minded to be close minded- Zeppo Marx.Thanks very much for your patience and kindness... Ok if you read my argument it is this: An INCREMENTALLY set of additions in a series of experiments cannot be ONLY placebos... Adding one schumann generator after another one cannot be entirely illusory... In some acoustically uncontrolled room some people could hear no difference, BECAUSE their room and system is too noisy...Like i said i dont recommend S.G. for first step in embeddings controls... It work for me first because my room is very heavily acoustically treated and under controls... Believe me or not i could distinguish between the difference of adding a single straw or not, to one of the main Helmholtz tube for example...Read about Helmholtz bottles you will know why... It is no bat hearing it is acoustic science... Then modifying the Schumann generators by connecting all of them or not, by adding shungite+copper or not on them , by adding herkimer diamonds or not on them ; all these additions are different experiments... Reducing them to placebos effects is preposterous completely... A incremental set of experiments is not a piece of sugar in medecine... |
thecarpathian2,007 posts02-24-2021 12:24pmSerious question for anyone- If it's the Earth’s natural frequency, then that frequency is already in the room. Why would you need to generate it? <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<>>>>>>>>>>>>>>>>>>>>> 7.83 Hz. This is the frequency that the earth/atmosphere system “rings” at when the Earth IS STRUCK BY LIGNTNING. it does not ring at 7.83 MOST of the time...Not some MOST of the time. It is also a common frequency your brain “ticks” at. NOT THE ONLY ONE and NOT all the time.. We are leaving out a lot here folks.. Regards |
