The best sounds for sleeping
Finding the right background sound can transform your sleeping experience. This activity engages your Sleep Onset + Sleep Maintenance cognitive systems, which respond best to specific types of ambient sound.
Research says: Pink noise during sleep extends deep sleep (slow-wave sleep) by 25% and improves next-day memory recall. Pink noise matches the brain's own sleep oscillation frequency, reinforcing the slow waves responsible for memory consolidation. A separate ICU study found pink noise reduced time to fall asleep by 40%.

The most universally effective sleep sound. Pink noise spectrum, parasympathetic activation, evolutionary safety signal. ICU studies show 40% faster sleep onset.
Recommended: 40-50 dBpink noise
The strongest scientific evidence: 25% deeper sleep, improved memory consolidation (Northwestern).
Recommended: 35-45 dBbrown noise
The TikTok favourite. Deep, enveloping, warm. Excellent for masking urban noise. Evidence is anecdotal but user reports are overwhelmingly positive.

Conseil pro
Use a timer (45-90 minutes) rather than playing all night. Basner et al. (2025, UPenn) found continuous pink noise at 50 dB reduces REM sleep by ~18 minutes. Let it help you fall asleep, then let silence take over.
Questions fréquentes
Is it safe to listen to sounds all night?
The volume is the key factor. Below 50 dB, there's no hearing risk. However, recent research suggests continuous noise may reduce REM sleep. A timer (45-90 min with gradual fade) gives you the sleep-onset benefits without overnight exposure.
What does research say about sounds for sleeping?
Pink noise during sleep extends deep sleep (slow-wave sleep) by 25% and improves next-day memory recall. Pink noise matches the brain's own sleep oscillation frequency, reinforcing the slow waves responsible for memory consolidation. A separate ICU study found pink noise reduced time to fall asleep by 40%. (Papalambros et al., Northwestern University / Frontiers in Human Neuroscience, 2017)
What volume should I use for sleeping?
For sleeping, set your volume to 40-50 dB. This range is based on acoustic research — loud enough to mask distracting noise, quiet enough to avoid auditory fatigue during extended listening.
