- Schumann wave itself does not make any sound, it is not directly acting on the sound or video products to improve the quality of sound or vision. It's working on the space environment, make the people's physical and mental get relaxed, improve the body's perception of sound and images, improve the human body health and working efficiency, it also has a good effect on insomnia, mental strain and so on. For more information please Google "Schumann Resonance".
- For audio-visual space - to enhance the sound field and audio-visual effects
For the bedroom - to help sleep soothe the nerves, treatment of insomnia
For the office - relax and improve work efficiency

The FM 783 Schumann wave generator is an auxiliary device that acts on the human body at a relatively weak frequency, and Schumann wave will fail in the following cases: the surrounding environment is too noisy, all kinds of waveform more far than the Schumann wave generator radiation intensity. the body is excited, excited state. each type of continuity under the big volume of DJ music.
Suggested that the goods placed a height of 1.5 meters, a single product should be in the area of not more than 18 square meters, more than one, please purchase more than one. It is recommended to use a matching linear power supply.
① HIFI Application Principle：
Drive off the clutter + clean listening environment + enhance the body perception = system upgrade.
a. HIFI speaker system applications:
18 square meters of kiss environment, Will schumann wave level placed in the middle of the two speakers, after a little, when the conditions allowed to place a height of 1.2-1.5 m, Schumann wave to avoid vibration or anti-vibration treatment can enhance More than 18 square meters of listening environment, it is recommended to buy two, Can be schumann wave put on top of the box or around, Other requirements are the same as above
b. Hifi application system:
Because only the use of headphones to listen, in the effect, only the remaining "to enhance the human body perception", although the effect of a sudden drop, but still exist.
② Film direction application:
The required number of Schumann wave and placement and HIFI application of the same, for more than 40 square use of the environment HIFI players, Suggested use 4 pieces of Schumann wave generator.
③ Help sleep direction:
Because each person has a different perception and there are individual differences, some people first application of the middle of the night sleep quality is not too high, after several days to adapt, to achieve deep sleep.
④ Creative direction:
Often used in calligraphy and painting, designers, can meditate.
⑤ Other direction:
Meditation, Martial arts practice, Taoist culture research, biology, medicine and other direction
Schumann wave applied to HIFI, the performance in the details of the players require a certain appreciation of the ability, we made a small proposal to the domestic players trial reference:
has many years of experience in HIFI, can appreciate the advantages and disadvantages of different combinations of equipment capacity.
their own HIFI equipment level can not be too low
can be heard, the difference between the different systems on the same line to bring the tone changes (focus).
Advertised as a 7.83 Hz Schumann resonance generator with room-scale coverage — my testing did not support either claim.
I bought this unit because it is advertised as producing a 7.83 Hz Schumann resonance signal, and the instructions state that it is intended for use in an area of up to 18 square meters, or about 194 square feet.
I decided to test the unit rather than judge it by whether I could hear or “feel” anything. I used the three-axis magnetometer in my phone with FFT spectrum analysis and repeated controlled measurements with the unit ON and OFF. I increased the FFT window to 4096 samples at approximately 100 Hz sampling, which gave roughly 0.024 Hz frequency resolution. I also repeated the measurements in different sequences, kept the phone and device stationary during comparisons, and tested the signal at multiple distances.
The results were consistent enough to raise serious concerns.
At extremely close range — roughly 0.5 to 1 cm from the device — I repeatedly measured a strong narrow magnetic-spectrum peak around 8.2 to 8.24 Hz.
That is not the advertised 7.83 Hz.
In one direct ON/OFF comparison at essentially the same position, the ~8.24 Hz component measured approximately 175 spectral units with the device ON and approximately 8 units with it OFF, a drop of more than 20×. Repeating the ON measurement reproduced the same ~8.2–8.24 Hz feature.
The range was also disappointing.
At approximately 1 foot away, the ~8.24 Hz signal dropped from roughly 175 units at near-contact distance to around 11 units, which was close to the surrounding background level.
At approximately 3 feet away, the ~8.24 Hz component was no longer clearly distinguishable from background magnetic noise.
In plain English:
The device appears to generate a measurable low-frequency magnetic field, but in my testing the strongest signal was around 8.24 Hz rather than 7.83 Hz, and the measurable signal was only strong when the sensor was essentially touching the unit. By about 1 foot away it had already fallen near the noise floor, and by 3 feet it was effectively indistinguishable from background.
That is very difficult to reconcile with instructions suggesting useful operation over an area of up to 18 m² / 194 ft².
I understand that a smartphone magnetometer is not a several-hundred-dollar calibrated ELF laboratory meter, so I am not claiming laboratory certification of the absolute field strength or exact frequency. However, this was not a single casual phone reading. I performed repeated ON/OFF controls, replicated the same close-range peak, reversed test order, increased spectral resolution, kept orientation consistent, and tested distance dependence.
The device clearly produced a repeatable close-range effect. The problem is that the effect I could actually measure was centered around ~8.24 Hz, not 7.83 Hz, and it dropped off extremely quickly with distance.
I have contacted the company asking for:
* the expected frequency tolerance of the unit,
* expected field strength at different distances,
* the manufacturer’s test procedure,
* any available independent laboratory data,
* and a properly tested/calibrated replacement.
I also have the screen recordings and exported measurement data available if their technical staff want to review it.
At this price, customers should not have to purchase hundreds of dollars of specialized test equipment just to verify that a product advertised as a 7.83 Hz generator is actually producing 7.83 Hz at a practically useful distance.
I will update this review if the company provides a satisfactory technical explanation, replacement, or other resolution.
Thank the Schumann-REsonator, my Audiosystem brings more finesse, resolution, and contrast. Top !
I didn't have high expectations, but my sleep has improved beyond belief.
Makes no sound, but I don't think it is supposed to, so that's okay. Is it really working? Maybe, no way to verify if it is generating anything. I don't perceive any difference in my sleep or other. I will still let it run, just in case. I do like that the wood does not have any offensive smells or glue smells, thank you!
Purchased this to help with sleep in conjunction with a good grounding mat I've had for several months. It might be helping but too many other variables, right now.
