How to Block Out Noise at Night

If a sound is keeping you up — traffic, a neighbor, a snoring partner, a hallway door — the tip you need depends on what kind of noise problem you actually have. A closed gap under a door helps with a different kind of noise than a white-noise machine does, and neither one helps at all with a genuinely medical issue like a partner’s sleep apnea. This guide is organized around that decision, not around a generic list of tips: figure out what’s happening, reduce it where you can, block or absorb what’s left, mask what can’t be removed, and know when the honest answer is that an article can’t fix it.

Start Here: What Kind of Noise Is This?

For context, World Health Organization community-noise guidance recommends less than 30 dB(A) in bedrooms at night for good-quality sleep. That is a population-level guideline, not a precise pass-or-fail test for an individual bedroom, and identifying the type and source of the noise is usually more useful than focusing on one number. A few quick questions narrow down which sections below actually apply to you:

• Is it continuous or intermittent? A steady hum (traffic, an HVAC system, a fan) is often easier to mask than a sound that starts and stops unpredictably (a slamming door, a barking dog, a passing siren) — unpredictable noise is more likely to wake you specifically because it’s unpredictable.
• Is it coming from outside the room, or from inside it? Exterior noise (traffic, neighbors, aircraft) usually needs a blocking or masking response. Interior noise (a snoring partner, a pet, your own household) is often more about the source itself — a conversation, a schedule change, a medical conversation — than about the room’s construction.
• Is the source something you can change at all? A rattling window latch or a too-loud TV are fixable at the source. Airport flight paths and a neighbor’s schedule generally aren’t — those need blocking, masking, or a different kind of response covered in “Special Situations” below.

If you’re not sure, start with Reduce the Source below regardless — it’s free, and it’s worth ruling out before spending money or effort on anything else.

Reduce the Source First

The cheapest, most effective fix for any noise problem is one where the noise itself gets quieter or goes away — before it ever has to be blocked or masked. A few places this is realistic:

• Something in your own home. A rattling appliance, a device left on, a TV or speaker at a louder volume than necessary, a door that slams instead of closing quietly — these are often the easiest wins available, because you control them directly.
• A household member’s routine. A later bedtime for someone else in the home, headphones instead of a speaker after a certain hour, or simply asking doesn’t fix everything, but it’s worth trying before assuming nothing can change.
• A neighbor or shared space. A brief, non-confrontational conversation resolves more of these situations than people expect — many people genuinely don’t realize how much sound carries through a shared wall, floor, or hallway. See “Neighbors and Shared Walls” below for how to approach this if a conversation doesn’t help.
• Moving to a quieter room, if one’s available. Not realistic for everyone, but worth considering if one room in your home is reliably quieter than another.

Source reduction won’t apply to every situation — you can’t quiet a highway or change an aircraft flight path — but it’s worth ruling out first specifically because it’s free and, when it works, it solves the actual problem instead of working around it.

Close the Easiest Sound Paths

Sound, like air, moves through gaps — the same seals that stop a draft under a door or around a window frame do real work against sound for the same physical reason. This is a low-cost step worth trying before anything more elaborate:

• Weatherstripping around a door or window frame closes an obvious, direct path for sound (and air) to travel through. It’s inexpensive, generally renter-safe, and reversible.
• A door sweep (a strip that seals the gap between a door’s bottom edge and the floor) closes what’s often one of the largest sound leaks in a room, for the same reason a door left slightly open lets in noticeably more noise than one that’s fully sealed.
• Heavy curtains or blackout curtains can take the edge off some sound, especially higher- pitched noise like traffic or voices — they’re more limited against low, rumbling sound like heavy trucks or bass. They help, but they don’t come close to soundproofing a room, whatever a product listing might imply.

None of this makes a loud room silent. It reduces how much sound actually reaches the room in the first place, which is a meaningfully different (and generally more effective) job than trying to cover the sound up once it’s already inside.

Adjust the Room and Bed Location

Two related but genuinely different things happen here, and it’s worth keeping them separate:

Moving the bed matters more than most people expect. Sound generally gets weaker with distance from its source, so moving the bed away from the wall or window closest to the noise — even by a few feet, even within the same room — can make a real difference. This is one of the few genuinely free changes on this list.

Furniture and soft materials mostly change the room’s echo, not how much outside sound gets in. A rug can soften footstep noise and reduce reflection inside the room; a foam panel absorbs sound bouncing around inside the room, which is a real and useful thing for making a room feel less “live” or echoey. But absorbing sound inside a room is a different property from blocking sound from entering the room — foam panels and rugs do very little of the second one, no matter how the products marketing them may be worded. If your problem is specifically noise coming from outside the room, closing gaps (above) and moving your bed away from the source generally do more than adding soft furnishings will.

Mask What You Can’t Remove

Once you’ve reduced what you can and blocked what’s practical, some noise is often still going to get through — that’s where masking comes in. Masking means adding a new, steady sound so the noise you can’t control is less noticeable against it, not eliminating the noise itself.

The evidence for masking sounds — white, pink, brown, or otherwise — is genuinely mixed, not a settled fact. Some studies find real benefits, including one finding people fell asleep noticeably faster with white noise playing. But researchers reviewing the overall evidence describe it as inconsistent and not yet strong enough to broadly recommend any specific sound as a proven sleep aid — several of the more encouraging studies were done with hospital patients trying to sleep through a loud clinical environment, which isn’t automatically the same as an ordinary bedroom.

No “color” of noise has been shown to be reliably better than another for sleep, whatever you may have seen claimed online:

• White noise is broadband sound with roughly equal energy across the audible frequency range — closer to television static than to any natural sound.
• Pink noise reduces higher frequencies, giving it a lower, steadier quality, sometimes compared to a waterfall. Some small research in older adults specifically has found a benefit for deep sleep in that group — a limited, specific finding, not a general “pink beats white” result.
• Brown noise reduces high frequencies further still, for an even deeper, lower sound. It has some research behind it for other uses, but its effect on sleep specifically hasn’t been well studied — the popular claim that it’s especially calming or medically beneficial for sleep isn’t something the current evidence actually supports.

A practical, defensible approach: use a steady sound you personally find comfortable, at the lowest volume that actually helps. A fan is one of the simplest, cheapest ways to do this, and many people already own one. A dedicated sound machine or app works the same way. What matters more than which specific sound you choose is keeping the volume reasonable — see the hearing- safety note below.

Use Earplugs and Personal Audio Carefully

Earplugs and sleep earbuds are a legitimate personal layer of protection — but they deserve more care than “just get some,” and both carry real risks worth knowing.

Earplugs:

• Fit matters more than maximum noise reduction. A plug that’s too large won’t seal properly and will be uncomfortable; one that’s too small won’t reduce sound enough and may fall out. Foam, premolded (silicone/plastic), and wax earplugs each fit and feel different — it’s worth trying more than one type.
• Hygiene matters. Wash your hands before inserting earplugs. Disposable foam plugs have an open, porous structure that can harbor bacteria if reused too long — replace them regularly rather than stretching one pair for weeks.
• Earplugs can be useful when other changes aren’t enough, but they may cause irritation, wax buildup, discomfort, or infection for some people. The two most common issues: earwax pushed inward and compacted against the eardrum (which can be genuinely painful and may need a clinician to remove), and a warm, sealed ear canal that’s more hospitable to bacterial or fungal growth, which can lead to an outer-ear infection. Clean hands, a proper fit, and cleaning or replacing earplugs appropriately for their material all reduce the risk — and it’s worth stopping and checking in with a clinician if you notice pain, itching, or drainage.
• Skip earplugs, or check with a clinician first, if you have a perforated eardrum, an active ear infection, recent ear surgery, or ear pain, drainage, sudden hearing changes, or persistent ringing (tinnitus). Inserting anything into a compromised ear canal can make an existing problem worse.
• Earplugs reduce your ability to hear alarms, a child, or an emergency, including smoke and carbon-monoxide alarms — a real, practical safety tradeoff worth thinking through, especially if you’re the only adult who’d hear an alert, or if anyone in your home has any degree of hearing loss. A visual alert device (a strobe smoke alarm, a bed-shaker alarm) is a reasonable backup for someone who relies on earplugs nightly.

Sleep earbuds and headphones raise a few additional, distinct concerns beyond earplugs:

• Ear-canal pressure and irritation from a device sitting directly in the canal, especially for side sleepers, and especially with a poor-fitting pair.
• Trapped moisture, which — like earplugs — can create conditions favorable to bacterial growth.
• Earwax pushed deeper into the canal, the same concern as earplugs, from anything sitting in the ear overnight.
• Volume is worth treating as a habit, not a target number. General hearing-safety guidance from NIDCD describes sound at or below about 70 decibels as generally safe even with long exposure, and repeated exposure at 85 decibels or higher as a real risk for lasting hearing damage — but that’s broad hearing-safety guidance, not a recommendation aimed at overnight headphone use specifically. For overnight listening, Cleveland Clinic’s practical guidance is simpler: keep the volume at around half of the device’s maximum or lower, use a sleep timer so audio doesn’t keep playing at volume all night, and avoid active noise cancellation, since it can make it harder to hear something you need to hear.
• Over-ear sleep headphones (a soft, flat headband style) or a speaker across the room avoid most of the in-ear risks above, and are worth considering as an alternative if you find yourself using earbuds nightly.

Special Situations

A snoring partner. Ordinary, occasional snoring is genuinely just noise, and masking or earplugs are a reasonable personal accommodation for it. But it’s worth knowing the difference: loud, frequent snoring — especially with pauses in breathing, gasping or choking sounds, or your partner’s own daytime sleepiness, morning headaches, or restless sleep — is a recognized warning sign of obstructive sleep apnea, a real, treatable medical condition. That’s a conversation for a healthcare provider, not something to sleep through with a fan running. See Why Do I Wake Up in the Middle of the Night? for more on nighttime breathing-related waking and when it’s worth a medical evaluation.

Neighbors and shared walls. Start with the least confrontational step that’s realistic: a direct, non-accusatory conversation, if it feels safe to have one — many people don’t realize how much sound carries through a shared wall, floor, or ceiling until someone mentions it. If a conversation doesn’t help, document the dates and times and review your lease, building rules, and local government guidance before deciding what to do next — the specifics vary too much by city and building type for a general article to advise on responsibly.

Traffic, aircraft, and trains. These are usually the least fixable at the source for an individual renter or homeowner. The blocking, room-adjustment, and masking sections above are the realistic options; for a genuinely severe, ongoing situation near an airport or major road, some homeowners pursue more substantial soundproofing (specialized window replacement, added wall mass) — a bigger investment than this article’s scope, worth researching separately if the cheaper layers above aren’t enough.

Shift work, travel, and unfamiliar rooms. The noise problem here is often less about a single loud source and more about trying to sleep during hours when your household and neighborhood are naturally louder, or in a room you don’t control (a hotel, a dorm). Portable options — earplugs, a phone-based masking sound, an eye mask for the daylight half of the equation — travel well and don’t require any permanent change to a space you don’t control.

What Common Fixes Can and Can’t Do

When the Problem Needs a Different Kind of Help

Some noise problems genuinely aren’t solvable with a tip list, and it’s worth naming those plainly rather than implying one more product would have fixed it:

• A snoring or breathing-related noise from a partner, especially with the warning signs described above, is a medical conversation, not a masking problem.
• A noise source tied to safety — a smoke alarm you can’t hear because of earplugs, an emergency you need to be able to respond to, a household conflict that’s escalating rather than resolving — needs a direct response, not a workaround.
• A persistent, unresolved conflict with a neighbor or landlord may need documentation, a formal complaint, or in some situations legal guidance specific to your lease and location — beyond what a general sleep-health article can respectfully advise on.
• A housing or community noise problem that genuinely can’t be fixed from inside the unit (a flight path, a highway, an industrial neighbor) is a real, legitimate limitation. It’s not a personal failure to have tried the steps above and still have a noise problem. Some severe noise problems may ultimately require structural improvements, help from property management, or a different sleeping space — options that aren’t always practical or affordable.

This article can’t tell you which category your specific situation falls into. If you’ve tried reducing, blocking, and masking and you’re still consistently losing sleep to noise — or if what’s keeping you up sounds more like a health, safety, or housing issue than an environmental one — that’s a reasonable point to bring in a person, not another tip.
