Questions
- What is the best sound to sleep to?
- There is no single best one. Most people pick a steady sound with no sudden changes, such as rain, ocean waves or noise, because it hides the sounds around them. Try a few and keep the one you stop noticing.
- Do sleep sounds work?
- Many people say a steady sound helps them drift off, mostly because it hides sudden noises. The research is still thin: a 2021 review of 38 studies rated the evidence for noise as a sleep aid as very low quality. Source: Riedy et al., “Noise as a sleep aid: a systematic review”, Sleep Medicine Reviews, 2021.
- Can I leave it on all night?
- Yes. It plays until you pause it, or set the sleep timer for up to 10 hours. Keep the volume low, just loud enough to soften the noises around you.
- Rain or brown noise: which is better for sleep?
- It is personal. Rain has texture, with drops and patter; brown noise is a smooth, even rumble. This mix uses both, and the two sliders let you lean either way.
- Is it free?
- Yes, for now everything is free, the real recordings included. There is nothing to sign up for, nothing to install and no ads. Later some real recordings may move to a paid option; the sounds made in your browser will stay free.
