Prof. William Dalton, Ph.D.Pink noise is the scientifically-documented winner in sleep improvement. Its balanced frequency profile promotes deep, slow-wave sleep cycles. This noise color greatly improves memory consolidation. Older adults get powerful benefits. You gain more natural rest that is restorative.
Fully understand the mechanisms of pink noise. Its energy-balanced distribution by frequency matches the frequencies naturally produced in the brain. This sync causes a greater level of delta wave activity during deep sleep. Several clinical trials have shown a 25% improvement in memory function. The brain processes daily events more efficiently.
For Deep Sleep Seekers

- Position machines 4 feet from bed
- Set volume between 50-60dB
- Use consistently for 2+ weeks
For Tinnitus Sufferers
- Brown noise masks low-frequency ringing
- Focus on 100-150Hz frequency range

Try the Best Settings tonight. Start tonight with pink noise to improve your sleep overall. If low-frequency disturbances annoy us, we use brown noise; if racing thoughts prevent sleep, we use green noise. Use a Volume of 45-60dB to suit your sensitivity. Your sleep solution is here.
Unique populations gain targeted benefits from certain colors of noise. Shift workers benefit from the circadian enhancement of pink noise. Students improve their exam recall with enhanced memory. People suffering from post-traumatic stress find green noise decreases nighttime anxiety. The optimal choice is based on your unique requirements.
