## Key facts
- White noise = equal energy at every frequency (bright hiss); pink noise = balanced, softer (like rain); brown noise = deep, low rumble with the highs rolled off.
- Brown and pink noise are the most popular for sleep; white noise is best for masking sudden sounds.
- Grey and violet noise are commonly used for tinnitus masking.
- The sleep timer fades the sound out gently before stopping.
- It is a free relaxation tool, not a medical treatment. A systematic review of 38 studies (Riedy et al., Sleep Medicine Reviews) rated the evidence that continuous noise improves sleep as limited.
- All 16 sounds are synthesized in-house (no licensed recordings) and loop without a gap.
- For babies: keep the volume low and the speaker about 2 metres from the crib (Hugh et al., Pediatrics 2014).

## Sound catalogue
- Brown Noise: Deep, low and grounding — A deep, rumbling noise with the high frequencies rolled off. Brown noise feels like distant thunder or a steady waterfall — many people find it the most calming for focus and deep sleep.
- Pink Noise: Soft and balanced — Balanced across the spectrum with gentle, even energy — softer than white noise. Pink noise resembles steady rainfall and is often used to improve deep sleep and mask background sound.
- White Noise: Pure, even masking — Equal energy at every frequency — the classic static hiss. White noise is the most effective at masking sudden sounds like traffic, voices or a snoring partner.
- Green Noise: The hush of nature — Mid-frequency noise centred around the ambient sound of the natural world — like a calm forest or a faraway stream. Soothing without the brightness of white noise.
- Grey Noise: Balanced for the ear — Tuned to how the ear actually hears, so every frequency feels equally present. A soft, even blanket of sound — popular for tinnitus relief and deep focus.
- Blue Noise: Bright and airy — Energy rising toward the high frequencies for a crisp, airy hiss. Blue noise is a favourite for masking ringing in the ears and for a lighter, brighter backdrop.
- Violet Noise: Crisp and high — Energy concentrated in the very high frequencies for a fine, delicate hiss — the mirror image of brown noise. A go-to for masking high-pitched ringing and tinnitus.
- Ocean Waves: Slow rolling surf — Waves swelling and breaking in a slow, endless rhythm. The gentle rise and fall mirrors calm breathing, making it a beautiful companion for winding down.
- Rain: Steady, gentle rainfall — A soft, continuous shower with no thunder to startle you. Steady rain is one of the most loved sounds for sleep, reading and quiet concentration.
- Stream: A bubbling brook — A gentle brook trickling over stones — light, bright and always moving, without the heaviness of a waterfall. Fresh and calming for focus or rest.
- Waterfall: Steady falling water — A constant, powerful cascade of water. Fuller and deeper than rain, it wraps the room in a smooth, even roar that drowns out everything else.
- Wind: Gentle gusts — A soft, gusting wind that rises and falls. The slow movement gives the calm of an open landscape without becoming distracting.
- Fan: Warm, steady airflow — The familiar, even hum of a fan or air conditioner — a low rumble under a smooth layer of airflow. Comforting, consistent and great for masking household noise.
- Airplane Cabin: Deep cabin hum — The steady, enveloping drone of a plane at cruise — a deep rumble beneath a smooth layer of rushing air. One of the most loved sounds for falling asleep anywhere.
- Fireplace: Crackling wood fire — The warm roar and soft crackle of a wood fire. Cosy and grounding — perfect for reading, relaxing or drifting off on a cold night.
- Heartbeat: A calm, resting pulse — A slow, resting heartbeat over the soft hush of the womb — deeply soothing, and a classic for settling babies, and adults, to sleep.
