How to block out noise when sleeping
You cannot make the street quieter. You can change how much each sound stands out. These five steps use sound to do it, work with or without earplugs, and cost nothing to try tonight.
1. Raise the floor
A room is never silent, it is quiet with gaps. Interruptions land in the gaps. A steady sound fills them, so the next door or engine has less to stand out against. Brown noise is the usual starting point because it is deep and easy to forget. Press play above.
2. Put the speaker between you and the noise
Masking works on contrast at your ear. If the noise comes through the window, the speaker goes near the window. If it is a snorer, the speaker goes on the bedside table between you. Do not put it behind your head.
3. Keep it steady all night
Most apps and machines offer a timer. Turn it off. The late-night bin truck and the 5 am neighbour arrive after most timers have ended. A seamless loop at a low level, all night, is the setting that actually works.
4. Match the sound to the problem
| The problem | Try | Notes |
|---|---|---|
| Traffic, planes, a hum through the wall | Brown noise | Low and steady, like the problem sound itself. |
| Voices, TV next door, a party | Noise Blanket | Shaped to sit under speech. |
| A snorer, dishes, doors | White noise | Brighter, covers sharp sounds better. Pair with earplugs if loud. |
| Nothing specific, just a scattered mind | Fire & Rain | Close, warm nature bed for evenings. |
5. Give it a week, and turn it down as you go
The first night a new sound is a new event. By the third you stop hearing it. From there, lower the level each week until it is the quietest setting that still covers the problem. Louder is not better. The goal is a floor, not a wall.
Earplugs plus sound
Earplugs cut the level of everything, including the masking. Sound reduces contrast. Used together they handle the loudest situations, like a snorer in the same bed. Foam plugs with a speaker across the room is the combination most people settle on.
What the research says, honestly
- Sleep, broadband noise: a 2021 systematic review of 38 studies (Riedy and colleagues, Sleep Medicine Reviews) found results ranging from improved to disrupted sleep and rated the overall evidence quality as very low. A 2022 review (Capezuti and colleagues, Journal of Clinical Sleep Medicine) found 19 of 34 studies positive and still called the evidence weak. Capezuti 2022
- Masking itself is not in doubt: raising the sound floor reduces how far a sudden sound rises above it. It has been engineered into office ceilings and hospitals since the 1960s, and 310 registered clinical studies involve sound masking. ClinicalTrials.gov
- Attention: a 2024 study in Communications Biology (Northeastern University, NSF-funded) found rapidly modulated sound supported sustained attention, with the largest effect in people with attention difficulties. Reviews of white and pink noise in ADHD report small, individual benefits. Brown-noise-specific trials are still thin. Coverage of the 2024 study
- Deep sleep: a 2017 Northwestern study of 13 older adults timed pink noise pulses to slow waves and reported better overnight memory. Small, promising, early. Papalambros 2017
So: a mechanism that is well understood, outcomes that vary by person, and a lot of active research. That is why NeuroNest asks you to test it for five minutes instead of promising you anything.
When sound is not enough
If you have trouble sleeping most nights for more than a few weeks, see a doctor. Sound can make a noisy room easier to sleep in. It is not a treatment for insomnia, and NeuroNest does not claim to be one.
Questions people ask
How to block out noise when sleeping without earplugs?
Play a steady sound from a speaker placed between you and the noise, at a level you could talk over, all night without a timer. Brown noise for low rumbles, white noise for sharp sounds.
What is the best noise to block out snoring?
White noise or a brighter bed, placed between you and the snorer. For loud snoring, add foam earplugs. Masking works best on steady sounds and less well on irregular loud ones.
Can I use my phone speaker?
Yes to start. A small Bluetooth speaker is better for all-night use because it can sit where the noise comes from and does not need your phone beside your head.
Is NeuroNest free?
Yes. The sounds on this page play in your browser with no sign-up. The free app has the full-length versions.
