Green Noise for Deep Sleep
Mid-Range Spectral Sound Tuned to Nature's Frequency Profile

Green noise occupies the mid-range of the sound spectrum — centred around 500 Hz — producing a balanced, nature-like tonality that many listeners find more comfortable than the harsher high frequencies of white noise or the deep rumble of brown noise. The frequency profile closely matches the acoustic signature of natural environments: wind through grassland, flowing water, rustling leaves.
This makes green noise feel instinctively familiar and calming, even though it contains no actual nature recordings. The effect is a smooth, consistent sound blanket that masks disruptive noises without the fatigue that can come from extended white noise exposure.
Green noise has gained significant attention in sleep research and wellness communities as the optimal middle ground between stimulating and sedating coloured noise variants. This recording provides continuous, uninterrupted green noise for all-night use — no loops, no gaps, no variation. Just steady, natural-spectrum sound designed to carry you from wakefulness through to morning.
