Sleep sounds

Up to 30 minutes

For a nap or for drifting off: short sounds that fade out gently at the end.

Rain and water

Regular drops and waves form a broadband cover; the ones with thunder are softened too.

Night and nature

Crickets, distant thunder, the crackle of a fire: a sparse but continuously living background.

Hum and travel

Train, ferry, washing machine and tumble dryer: familiar mechanical sounds with a slow rhythm.

Soft noise

Brown, pink and grey noise, fan and air conditioner: the flattest cover. Treble is softened, so it can play all night.

Melody and tone

A slow melody or a deep tone; the ones with beats need headphones, as their card says.

Journeys

• Dream GateA four-stage night-and-morning route over days: pre-sleep sounds and dream writing, 14 stops. There is no promise of lucid dreams; the aim is to pay attention to your dreams.

Evidence

This page has no evidence level of its own; each sound's level is on its card. A summary of the related claims:

• ◆ B

  Broadband noise and masking

  Continuous noise probably makes surrounding sounds less noticeable.

  Evidence level B: Moderate evidenceModerate evidenceReviewed 09/10/2026

  What don't we know? It is not clear that masking translates into protected sleep: in a 25-person lab study, adding pink noise to intermittent environmental noise worsened sleep structure further, and earplugs worked better.

  Findings and sources
• ▲ C

  Sleeping with white, pink or brown noise

  Evidence on sleep is low quality and mixed; in one study pink noise reduced REM sleep. Keep the volume low.

  Evidence level C: Preliminary/mixed evidencePreliminary/mixed evidenceReviewed 07/10/2026

  What don't we know? A systematic review of 38 studies rated the evidence 'very low' quality and warned that continuous noise may harm sleep and hearing.

  Findings and sources
• ◆ B

  Music before bed and sleep

  A slow, calm melody accompanies your bedtime routine; listening to music before bed probably improves subjective sleep quality.

  Evidence level B: Moderate evidenceModerate evidenceReviewed 09/10/2026

  What don't we know? No improvement in objective sleep measures was shown.

  Findings and sources
• ▲ C

  Binaural beats and sleep

  Research on sleep is at an early stage; there are small pilot studies.

  Evidence level C: Preliminary/mixed evidencePreliminary/mixed evidenceReviewed 07/10/2026

  What don't we know? Comparison conditions are weak (no control or a silent night) and samples are very small.
