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 wave (NIH — Normal EEG Waveforms)
- Beta (≈13–30 Hz) — active, alert states↗ Beta wave (NIH — Normal EEG Waveforms)
- Alpha (≈8–13 Hz) — relaxed wakefulness↗ Alpha wave (NIH — Normal EEG Waveforms)
- Theta (≈4–8 Hz) — light sleep, reverie↗ Theta wave
- Delta (≈0.5–4 Hz) — deep sleep↗ Delta wave (NIH — Normal EEG Waveforms)
- Schumann resonance (7.83 Hz) — Earth's atmospheric cavity↗ Schumann resonances (overview)
- Pink noise & sleep depth↗ Pink noise & sleep (PMC)
- Low-frequency noise & focus↗ Noise & cognitive performance (PubMed)
- Moderate ambient noise & creativity↗ Ambient noise & creativity (JCR)
- Nature soundscapes & stress recovery↗ Natural sounds & default mode network (Sci Rep)
- Binaural beats — review↗ Binaural beats review (PMC)
