Sound masking for better, deeper sleep
Fall asleep faster, stay asleep longer, and wake up refreshed with ambient noise
Try Sleep Sounds NowYour brain doesn't fully shut down during sleep—it continues monitoring for potential threats. Sudden sounds (a car door, a dog barking, a partner snoring) trigger alertness responses that fragment your sleep, even if you don't fully wake up.
Ambient noise creates a consistent sound blanket that masks these disruptions. Instead of silence punctuated by jarring sounds, your brain experiences steady, predictable audio that it learns to ignore.
Consistent sound helps quiet racing thoughts and creates a calming bedtime ritual.
Sound masking reduces awakenings from environmental noise disturbances.
Research suggests pink noise may enhance slow-wave (deep) sleep.
Pink noise has a balanced, natural quality—like steady rainfall or wind through trees. Most people find it the most pleasant for sleep. Research from Northwestern University found that pink noise during sleep improved memory consolidation in older adults.
Best for: Most sleepers, especially those new to sleep sounds
Brown noise has more bass, creating a deep, rumbling sound like a waterfall or distant thunder. Many people find it the most relaxing and "cozy" noise color.
Best for: Those who prefer deeper sounds, light sleepers in noisy environments
White noise contains all frequencies equally, creating a consistent "hiss." It's the most effective at masking a wide range of sounds but some find it too bright for sleeping.
Best for: Very noisy environments, people who already use fans for sleep
