Block out snoring, traffic, and noisy neighbors with consistent, soothing sound. A steady acoustic environment reduces micro-awakenings.
Research shows consistent background noise can significantly reduce sleep onset latency by occupying the brain's auditory cortex so intrusive thoughts have less room.
Consistent sound environments promote longer, uninterrupted sleep cycles — including the restorative deep sleep stages your body needs most.
Scientifically optimized sound profiles designed specifically for falling asleep and staying asleep.
Heavy, rumbling brown noise that's perfect for deep sleep. Low frequencies create a cocoon of sound that blocks out everything else.
Our most popular sleep preset — an optimized pink noise blend specifically tuned for falling asleep faster and staying asleep longer.
Soft, soothing mid-range frequencies that won't overwhelm. Ideal for light sleepers and those sensitive to loud or harsh sounds.
15, 30, 60, 90, or 120 minute options with gentle fade-out — so your phone doesn't play all night.
Keeps playing when your screen is locked, without draining battery excessively.
Quilence generates sound continuously — no loops, no audio glitches that could wake you.
Adjust frequencies from 40 Hz to 16 kHz to build your perfect sleep soundscape.
Our brains don't fully switch off during sleep — the auditory cortex remains active and responsive to sudden sounds. A car horn, a slamming door, or a partner shifting in bed can trigger micro-awakenings that fragment your sleep, even if you don't remember them in the morning. Over time, this adds up to chronic sleep debt.
Background noise works by raising your acoustic "floor" — it fills in the quiet gaps so that sudden sounds no longer stand out as sharply. This process, called auditory masking, reduces the contrast between ambient noise and disruptive sounds, making them less likely to trigger an arousal response.
Brown noise vs. pink noise vs. white noise for sleep: All three can be effective, but they work slightly differently. White noise (flat spectrum) is the broadest masker but can feel harsh. Pink noise attenuates higher frequencies and sounds softer. Brown noise goes even further — heavily emphasizing bass frequencies — which many people describe as the most "immersive" and easiest to sleep through. Quilence's 10-band EQ lets you tune any of these to your exact preference.
Research published in Sleep Medicine Reviews found that continuous background noise can reduce sleep onset latency (the time it takes to fall asleep) and improve sleep efficiency. The effect is particularly pronounced in noisy urban environments and for people who are light sleepers or prone to insomnia.
Yes. Brown noise has deep, low-frequency characteristics that many people find highly soothing. Studies show consistent background noise reduces sleep onset time by masking disruptive sounds and creating a stable acoustic environment.
White noise contains all frequencies equally — often described as a hiss. Brown noise emphasizes lower frequencies and sounds like a waterfall or heavy rain. Most people find brown noise easier to sleep to. With Quilence's 10-band EQ you can blend both to find your personal sweet spot.
A comfortable volume similar to a quiet fan or distant rain is usually most effective — roughly 40–55 dB. Quilence lets you set precise levels, and the sleep timer ensures it fades out after you've drifted off.
Yes. White and pink noise are widely recommended for infant sleep. Quilence's Gentle Mix uses soft, balanced frequencies that help babies stay asleep by masking household sounds. Always keep volume low for infants.
Absolutely. Quilence uses iOS background audio so it plays even with your screen off. You can control it from the Lock Screen and Control Center.
