How this page is funded: we earn a commission if you buy through the links below, at no extra cost to you. As an Amazon Associate we earn from qualifying purchases. It does not change which products we pick or the order they appear in. Full disclosure.
How these picks were made: by comparing published specifications and clearly-credited public reporting. We do not run a laboratory, we have not measured these products, and we do not claim to have slept with them. Here is exactly how we choose.
Footsteps above at midnight. A television through the wall. A bass line you can feel more than hear. Somebody’s front door at 2am. You cannot control any of it, which is what makes it so infuriating - but you can control a surprising amount of what reaches you.
How loud is actually too loud
Useful for calibration, and useful if you ever have to raise this with a landlord. The World Health Organization recommends keeping annual average night-time outdoor noise below 40 dB to prevent adverse health effects, and its community-noise guidance suggests under about 30 dB inside bedrooms for good-quality sleep. The threshold associated with waking is around 42 dB.
A published international guideline is a considerably more persuasive thing to cite in a complaint than “it is too loud”.
Try this tonight, for free, in this order
- Move the bed off the shared wall. The single most effective free change available. Even a couple of feet helps, and moving your head to the far side of the room helps a great deal.
- Put mass against that wall. A full bookcase, a loaded wardrobe. Mass is what blocks sound, and a heavy piece of furniture against a shared wall does more than any acoustic foam sold for the purpose - foam absorbs reflections within a room, it does not stop sound passing through a wall.
- Add soft furnishing. A rug, heavy curtains, a fabric headboard. Hard, empty rooms reflect sound and make everything sound closer and sharper.
- Seal the gaps. Sound leaks like water, and the gap under a bedroom door often carries more noise than the door itself. A draft excluder costs a few dollars.
- Talk to them. Once, politely. Genuinely worth doing. Most people have no idea their floor transmits, and most respond well the first time they are told.
The layered setup that works
For a genuinely bad situation, this combination costs less than one premium sound machine and beats it comfortably:
- Bed moved, mass against the wall - free
- Brown noise from a digital machine, placed between you and the wall rather than on the far side of the bed, so the mask arrives from the same direction as the noise. Why brown rather than white.
- Foam earplugs for the nights the first two are not enough - which to buy and how to insert them.
- A light or vibrating alarm, so the earplugs do not cost you the morning - the options.
The bass problem, honestly
Low frequencies are the hardest case and it is worth saying plainly that gear mostly loses here. Bass travels through the structure of a building rather than through the air, which means it arrives through the floor and the walls and you feel it as much as you hear it. Nothing masks a vibration, and foam earplugs block high frequencies far better than low ones.
What helps a little: mass against the transmitting surface, distance, brown noise rather than white, and active noise cancellation in sleep earbuds - which works best at exactly the low frequencies everything else struggles with. The sleep earbud roundup.
What does not help: acoustic foam panels, egg boxes, or any of the internet’s favorite cheap soundproofing. Those treat reflections inside a room, which is not your problem.
If none of it is enough
At some point this stops being a gear problem. If the noise is genuinely persistent and unreasonable, the route is the building manager, the landlord or the local authority, and the WHO figures above are worth citing. A pair of earplugs is a coping strategy, not a remedy, and there is a limit to how long anyone should treat somebody else’s noise as their own equipment problem.

Our top pick · Maximum blocking for the least money
1. Mack's Ultra Soft Foam Earplugs
The highest-rated foam plug in common retail, at a price where losing one in the sheets does not matter.
- Rating:
- NRR 33 dB (manufacturer figure)
- Material:
- Slow-recovery polyurethane foam
- Reuse:
- A few nights each, then discard
- Sold as:
- Bulk packs
What it gets right
- Nothing in common retail blocks more
- Cheap enough to replace constantly, which is also more hygienic
- The soft compound is tolerable for side sleepers once compressed correctly
Where it falls short
- Only works if you roll and insert them properly - most complaints are fit, not product
- Disposable, so there is an ongoing cost and ongoing waste
- At 33 dB you will very likely sleep through a standard alarm
Skip it if: You have to hear an alarm, a child, or a smoke detector. This is the wrong tool for that night.
Pick 2 · Digital variety without the loop artifact
2. LectroFan EVO
The digital machine that solved the loop problem: 22 sounds generated rather than played back, so there is no seam to notice.
- Type:
- Digital, non-looping synthesis
- Sounds:
- 22, including white, pink and brown noise plus fan sounds
- Volume:
- Precise stepped control across a wide range
- Moving parts:
- None
What it gets right
- Gives you brown and pink noise, which a mechanical fan cannot
- No motor means no mechanical hum and nothing to wear out
- Compact enough to pack
Where it falls short
- Digital sound is still digital - some people hear it as flatter than moving air
- No app or alarm features
- More expensive than budget machines with far longer preset lists
Skip it if: You specifically want the texture of real moving air. Get the Dohm instead.
Pick 3 · A snoring partner, specifically
3. Soundcore Sleep A30
The first sleep earbud with active noise cancellation, tuned for the low-frequency rumble that passive isolation cannot touch.
- Noise reduction:
- Active noise cancellation plus passive isolation
- Snore masking:
- Adaptive - responds to detected snoring
- Profile:
- Low-profile, side-sleeper oriented
- App:
- Yes, with sleep tracking
What it gets right
- ANC targets the low frequencies foam plugs and passive buds both struggle with
- Adaptive masking means the volume is not held constant all night
- Undercuts the premium sleep-bud competition on price
Where it falls short
- Most expensive option in this category by a wide margin
- ANC draws power, so battery life is shorter than the A20
- Feature depth you will never use if all you want is quiet
Skip it if: Your noise is high-frequency - traffic, chatter, a TV next door. Passive blocking handles that for far less.
Questions people actually ask
How do I block out noise from neighbors when sleeping?
Move the bed off the shared wall and put mass against it - a full bookcase or loaded wardrobe. Add soft furnishing to the room and seal the gap under the door. Then a sound machine playing brown noise between you and the wall, with earplugs for the worst nights.
Does acoustic foam block noise from neighbors?
No. Acoustic foam absorbs reflections within a room, which is a different problem from sound passing through a wall. Mass blocks sound transmission - a loaded bookcase against the shared wall does far more than any foam panel.
Why can I still hear bass through earplugs?
Bass travels through the structure of a building rather than through the air, so you feel it as much as hear it, and earplugs block high frequencies far better than low ones. Mass against the transmitting surface, distance, and active noise cancellation in sleep earbuds are the things that help.
How loud is too loud for a bedroom at night?
WHO guidance recommends keeping annual average night-time outdoor noise below 40 dB, and suggests under about 30 dB inside bedrooms for good-quality sleep, with the waking threshold around 42 dB. Those figures are useful to cite if you need to raise it with a landlord.
Should I talk to my noisy neighbor?
Once, politely, and it is genuinely worth doing. Most people have no idea how much their floor transmits, and most respond well the first time they are told. If it continues, the route is the building manager or the local authority rather than more gear.
