Binaural Beats Explained · What They Actually Do (and What They Don't)

When slightly different tones are presented separately to each ear, some listeners perceive a pulsing beat at the difference between them. That perception does not establish that the brain has entered a particular state. Research findings on wider effects vary.

The five families

• Delta (0.5–4 Hz)a range measured in brain activity, often associated with deep sleep
• Theta (4–8 Hz)a range observed in several states, including drowsiness
• Alpha (8–13 Hz)often observed during relaxed wakefulness
• Beta (13–30 Hz)a range present in many forms of waking activity
• Gamma (30–100 Hz)higher-frequency brain activity; not a promised listening outcome

What the research actually says

Some research has explored binaural beats in relation to relaxation, attention, and mood; findings are mixed and study methods vary. A pleasant listening experience is not evidence of treatment. These recordings should not replace medical care or medication.

Schumann resonance — the planet's own beat

Schumann resonances are electromagnetic phenomena in the Earth–ionosphere cavity. An audio tone is a different physical phenomenon; matching a number does not reproduce that field or establish a wellbeing effect.

Where to begin

Every binaural beat in the Soul in Love Sound Library is a mathematically-generated pure sine wave — no music on top, no third-party artist, no attribution required. Always use headphones (mono speakers cannot produce binaurals). Pick the brainwave that matches what your body is asking for. Notice. Do not push.
