Neuro-Acoustic Deep Sleep & 90-Min Circadian Engine
Evidence-based acoustic entrainment and sleep timing calculator to maximize Slow Wave Sleep (SWS) and glymphatic brain waste clearance.
Equal energy per octave, mirroring natural rain and atmospheric rustle.
🔬 Northwestern University trials demonstrated that 1/f acoustic stimulation enhances slow-wave sleep amplitude (N3) and boosts overnight memory retention.
Deep sub-harmonic resonance resembling a gentle waterfall or aircraft cabin.
🔬 Dampens hyperactive Default Mode Network (DMN) firing, halting racing bedtime thoughts and masking sudden ambient auditory spikes.
175 Hz left ear vs 177.5 Hz right ear with warm acoustic ambient backdrop.
🔬 Leverages the superior olivary complex to induce cortical brainwave synchronization into deep Delta rhythm (0.5 – 4 Hz).
Gentle, 8-second cyclical surf waves matching coherent breathing cadences.
🔬 Stimulates vagal afferents, lowering resting heart rate and assisting peripheral vasodilation for core body temperature drop.
