∿
Frequency 7.83 Hz
Your brain naturally produces alpha waves in the 8–12 Hz range — very close to Earth's resonance. During meditation, your brainwaves may entrain to this frequency.
⚡
High Amplitude Today
When SR amplitude spikes, it often correlates with increased lightning activity worldwide. Some practitioners report heightened sensitivity during these periods.
🧭
Geomagnetic Quiet (Kp 2.0)
Low geomagnetic activity means a stable ionosphere and cleaner SR signal. Ideal conditions for meditation and consciousness work tied to Earth frequencies.

What you are seeing
The science of the hum.
The Schumann resonance is the planet's base electromagnetic frequency — a global standing wave set up by lightning in the cavity between the Earth's surface and the ionosphere.
Predicted by physicist Winfried Otto Schumann in 1952 and first detected in the 1960s, its fundamental mode resonates near 7.83 Hz. The cavity's geometry fixes the pitch; storms, the Sun and the turning day shape its loudness.
Reading the data
- Frequency — the pitch of each mode. Extraordinarily stable for SR1 (~7.83 Hz).
- Amplitude (pT) — how loud each mode is. Spikes with global lightning.
- Quality factor Q — peak sharpness. Higher Q means a cleaner, longer-ringing resonance.
- Kp index — planetary geomagnetic disturbance, 0 (quiet) to 9 (storm).
- Phase angle — timing relationship between lightning excitation and cavity response.
- Signal quality — signal-to-noise ratio at the Tomsk receiver station.
Where the signal comes from
The spectrogram is the raw electromagnetic record of the Tomsk Space Observing System — vertical axis is frequency (0–40 Hz), horizontal is UTC time, colour is power.
Earth-Ionosphere cavity
The resonant cavity between Earth's surface (a good electrical conductor) and the ionosphere (a plasma layer at ~60–1000 km altitude) acts as a giant waveguide. Lightning discharges (~44 per second globally) continuously excite this cavity. The fundamental wavelength equals Earth's circumference (~40,000 km), giving the 7.83 Hz resonance. The ionosphere's height determines the harmonic spacing.
Questions
Frequently asked.
What is the Schumann resonance?
A set of global electromagnetic resonances excited by lightning in the cavity formed by Earth's surface and the ionosphere. The base frequency is 7.83 Hz.
What are the five harmonics?
SR1 (7.83 Hz), SR2 (14.3 Hz), SR3 (20.8 Hz), SR4 (27.3 Hz) and SR5 (33.8 Hz). Each has its own amplitude and quality factor, shown in the harmonics grid.
What is the quality factor (Q)?
Q measures how sharp each resonance peak is. The Schumann fundamental typically has Q ≈ 5–6, decreasing for higher modes.
Can I really hear it?
The true 7.83 Hz is below human hearing. Schumann Resonance Live pitches the fundamental and its harmonics up by octaves so the chord of the planet becomes audible.
Where does the live data come from?
The spectrogram is sourced from the Tomsk Space Observing System. Frequency, amplitude and harmonic values refresh continuously.
What is the phase angle?
The phase angle represents the timing relationship between lightning excitation and the resonant cavity's electromagnetic response. It varies with ionospheric conditions and cavity geometry.
How is signal quality calculated?
Signal quality reflects the signal-to-noise ratio at the Tomsk receiver, accounting for atmospheric noise, electromagnetic interference, and station conditions. Higher percentages indicate cleaner measurements.
What causes amplitude spikes?
Amplitude spikes are primarily caused by increased global lightning activity, particularly from major thunderstorm systems in the tropics and subtropics. Solar events and geomagnetic storms can also influence amplitude patterns.
Does the Schumann resonance affect human biology?
Research is ongoing. The 7.83 Hz fundamental overlaps with human alpha brainwave frequencies (8–12 Hz), and some studies suggest possible entrainment effects. However, more research is needed to establish definitive biological connections.
