Soulezy's sound design draws on standard EEG band research, studies of pink/brown noise on sleep and attention, the calming effect of natural soundscapes, and auditory entrainment techniques (binaural beats and isochronic pulses). Effects are gentle and individual — not medical claims.
- Gamma (≈30–100 Hz) — sustained attention↗ Gamma / 40 Hz stimulation & sustained attention (PMC)
- Beta (≈13–30 Hz) — active, alert states↗ Beta oscillations in movement & cognition (PMC review)
- Alpha (≈8–13 Hz) — relaxed wakefulness↗ The alpha rhythm: from physiology to behaviour (PMC review)
- Theta (≈4–8 Hz) — light sleep, reverie↗ Theta rhythm of the hippocampus (Front. Cell. Neurosci. review)
- Delta (≈0.5–4 Hz) — deep sleep↗ Electrophysiological correlates of sleep delta waves (PubMed)
- Schumann resonance (7.83 Hz) — Earth's atmospheric cavity↗ Schumann resonances (Remote Sensing review)
