Trouble falling asleep, night-time awakenings: sound can become a valuable ally for restoring quality sleep — if you choose it well.
Why sound helps sleep
A stable, predictable background masks disruptive noises (traffic, neighbours) that fragment sleep. It also occupies the mind just enough to stop it ruminating, while triggering the nervous system’s relaxation response.
Which sounds to favour?
- Brown or pink noise: lower than white noise, often perceived as softer and more enveloping
- Nature sounds: rain, waves, wind — soothing for many sleepers
- Slow music: tempo around 60 bpm, no lyrics or abrupt variations
The right settings
Keep the volume low, just above silence. Set a timer if you worry about being disturbed mid-night, or leave a continuous ambience if night awakenings are your main issue. Consistency matters: using the same sound ritual each evening helps the brain associate this signal with sleep.
What to avoid
Tracks with lyrics, rising intensity or marked rhythms can instead keep you awake. Likewise, falling asleep in front of a video brings screens and blue light — prefer sound alone.
In the Sound Doctor app, sleep sessions combine low frequencies and slow tempo to gently support falling asleep. Try different ambiences to find the one that suits you.
