Snoring is the single most common reason couples end up sleeping apart, and most of the advice for the person lying awake next to it comes down to "buy a white noise machine." That advice is half right. A masking sound does help, but plain white noise is a poor match for the specific sound it is trying to cover, and the way most people use it (quietly, on a timer) removes it before the snoring is at its worst.
The short answer: play a low-frequency sound such as brown or pink noise, all night, at a steady level around 50 to 60 decibels at your pillow. If the snoring is loud enough to punch through that, add well-fitted foam earplugs, because the two cover different parts of the problem. And if the snoring comes with gasping or pauses in breathing, the most effective fix is not in your ears at all. Below is why each piece works, with the research behind it.
What is the best way to block out snoring?
The best way to block out snoring is to layer two tools: a continuous low-frequency masking sound, such as brown or pink noise, played all night at a moderate level, plus foam earplugs if the snoring is loud. Masking hides the sudden start of each snore, and earplugs lower its peak. Neither one alone covers both.
The reason for the layering is that snoring disturbs sleep in two ways at once. It is loud in absolute terms, and it is intermittent, with each snore arriving out of relative silence. Earplugs attack the first problem by lowering everything that reaches your eardrum. A masking sound attacks the second by filling the silence between snores, so each one arrives as a smaller change. You want both effects, and each tool is weak at the other's job.
Why is a partner's snoring so hard to sleep through?
A partner's snoring is hard to sleep through because it is low-pitched, rhythmic, and intermittent. Most snoring energy sits between roughly 20 and 300 Hz, a range that travels through pillows and earplugs easily, and each snore starts abruptly out of quiet. The sleeping brain reacts to that sudden change, not just to the loudness.
The cost is measurable. In a 1999 study published in Mayo Clinic Proceedings, researchers ran simultaneous overnight sleep studies on 10 married couples in which the husband was being evaluated for sleep apnea. Midway through the night, the husbands were put on CPAP to stop the snoring. About 43% of the wives' arousals were linked to their husbands' snores, arousals dropped by 39% once the snoring stopped, and the wives' sleep efficiency rose from 74% to 87% of the night. That works out to more than an extra hour of sleep.
Loudness alone does not explain it, either. A 2012 study in Sleep and Breathing by Blumen and colleagues recorded 13 couples simultaneously and found that breathing noise intensity was comparable just before a partner's arousal and at other times. The partner was not simply woken by the loudest snore. Arousals track the size of the jump from background to peak. We covered that mechanism in detail in whether white noise should play all night or stop on a timer.
Does white noise block out snoring?
White noise partially blocks out snoring. It masks moderate snoring well enough to stop it waking you, but it is not the best match, because white noise puts most of its perceived energy in higher frequencies while snoring lives in the low bass range. Brown or pink noise covers that low range more efficiently at the same volume.
The detail that matters is how the energy is distributed. White noise has equal power at every frequency, which sounds balanced on paper. But hearing works in octaves, and each octave up contains twice as many frequencies as the one below it. So white noise gains about 3 dB per octave as you go up, which is why it sounds like a hiss. The octave from 5,000 to 10,000 Hz holds as much white noise energy as everything below 5,000 Hz put together.
Snoring sits at the other end. Acoustic studies of snorers report fundamental frequencies mostly between about 20 and 300 Hz, with palatal snoring (the soft palate vibrating) producing explosive low peaks under roughly 100 Hz. To cover that range with white noise, you have to turn it up until the hiss on top becomes the loudest thing in the room.
| Sound | Energy shape | Fit for snoring |
|---|---|---|
| White noise | Equal per Hz, rises 3 dB per octave, bright hiss | Works for moderate snoring, needs more volume to cover the bass |
| Pink noise | Equal per octave, balanced, like steady rain | Good all-rounder, covers low and mid snoring at a comfortable level |
| Brown noise | Falls 6 dB per octave, deep rumble | Best overlap with the 20 to 300 Hz snoring range |
| Fan or air conditioner | Mostly low and mid, uneven | Helps, but often has tonal hum and no volume control |
White noise still raises the floor and blunts each snore's onset; it is just the least efficient choice per decibel for this job. Our full comparison of brown, white, and pink noise covers the sound character of each.
Is brown noise better than white noise for snoring?
Brown noise is usually better than white noise for snoring because its energy is concentrated in the same low frequencies as the snore itself. It can cover snoring at a lower overall volume, and many people find its deep rumble easier to sleep to than a bright hiss. Pink noise is the middle option.
Masking works best when the masker overlaps the target in frequency: a sound centered at 2,000 Hz does little to hide a 120 Hz rumble. That is why brown noise feels so effective against snoring, traffic, and footsteps overhead.
The catch is that some snoring is not purely low. Snoring from the tongue base or with partial obstruction carries more energy in higher bands, and research on sleep apnea patients has found peak intensities above 1,000 Hz in some cases. If brown noise leaves a nasal or rattly edge audible, move to pink noise, or layer a little rain on top of the brown. Rain covers a broad band and is one of the most forgiving masking sounds, as we covered in the science of rain sounds for sleep.
Do earplugs work for snoring?
Earplugs work for snoring, but less well than the number on the package suggests. Foam earplugs are rated up to NRR 33, yet real-world protection is often half that, and all earplugs block low frequencies less effectively than high ones. Snoring is low-frequency, so it leaks through. Pairing earplugs with a masking sound closes the gap.
The Noise Reduction Rating is measured in a lab with trained fitters. Occupational safety bodies routinely discount it for real use: OSHA's method subtracts 7 from the NRR and then halves it for some purposes, and NIOSH recommends derating foam earplugs by 50%. An NRR 33 plug might realistically take 15 dB or so off, and less if it is not rolled and inserted deeply.
Two practical points make a large difference:
- Fit beats rating. Roll the foam into a tight thin cylinder, pull the top of your ear up and back to straighten the canal, insert, and hold it for 20 to 30 seconds while it expands. A plug sitting half out does very little against bass.
- Earplugs and masking combine well. Once the plugs shave off the sharper parts of a snore, a quiet brown noise only has to cover what is left, so it can run lower.
If foam irritates your ears, silicone or wax plugs trade some attenuation for comfort.
Do noise-cancelling earbuds help with snoring?
Noise-cancelling earbuds help with snoring less than people expect. Active noise cancellation is strongest against steady, predictable low-frequency sound, like an airplane cabin. Snoring is low-frequency but irregular, starting and stopping with each breath, which is harder to cancel. Sleep earbuds work best as a way to play masking sound close to your ear.
Active cancellation generates an inverted copy of incoming sound, which is easy for a repeating engine drone and harder for a sound that arrives abruptly and changes each time. In practice, the benefit of sleep earbuds for snoring comes mostly from passive blocking (the tips sealing your ear canal) and from delivering a masking sound at a very low volume right next to your ear, which your partner never hears.
That second point is a real advantage when your partner dislikes having a sound machine running. The trade-offs of wearing something in your ears every night (wax buildup, pressure, side-sleeping comfort) are covered in whether it is bad to sleep with earbuds every night.
How loud should a masking sound be for snoring?
A masking sound for snoring should usually sit around 50 to 60 decibels measured at your pillow, and should not exceed about 70. The aim is not to drown the snoring out completely but to raise the room's background level so each snore arrives as a smaller jump. Turn it up gradually until snores blur rather than stand out.
People tend to overshoot here, turning it up until the snoring disappears and landing well past 70 decibels. A better calibration: lie down while your partner is snoring, start low, and raise the level only until the snores stop sounding like distinct events. You will still hear them if you listen for them, and that is fine. Sleep is disrupted by sudden changes, not by sounds you can faintly detect. Our guide to how loud white noise should be for sleep explains how to measure the level at the pillow with a phone.
The other setting that matters is duration. Your own sleep gets lighter later in the night, with more REM and stage 2 sleep, and the snorer may have rolled onto their back, the position where snoring is typically worst. A 30-minute timer protects you during the part of the night you needed least help with. For snoring, play the sound all night.
Masking does not work by making snoring inaudible. It works by making each snore a smaller surprise. Set the level for that goal and you need far less volume than you think.
Should you just sleep in a separate room?
Sleeping in a separate room is a legitimate option, and it is common: 31% of US adults report some form of "sleep divorce" in a 2025 American Academy of Sleep Medicine survey. But one research study found that a single night apart did not substantially improve the partner's objective sleep, so it works best as a planned arrangement rather than an emergency escape.
The AASM survey, run in June 2025 with 2,007 US adults, found adults aged 35 to 44 most likely to sleep apart, at 39%. Snoring is consistently named as the leading reason in surveys of couples who do it.
The evidence on how much it helps is more mixed than the trend pieces suggest. A 2009 study in the European Respiratory Journal ran sleep studies on female partners of male snorers, once while sleeping with the snorer and once alone. Among the 16 women analyzed, the night alone reduced awakenings and light sleep, but total sleep time, sleep efficiency, and deep sleep were not significantly different. One night is a short window, so treat that as a caution against expecting a quick fix.
If you do move rooms and have come to rely on a masking sound, bring it with you. Our piece on not being able to sleep without white noise covers why that association forms.
When is snoring a sign of sleep apnea?
Snoring may be a sign of obstructive sleep apnea when it is loud and frequent, and especially when it comes with gasping, choking, or pauses in breathing, or with heavy daytime sleepiness in the snorer. Those signs warrant a doctor's evaluation. Treating apnea usually stops the snoring too, which helps both people in the bed.
The AASM estimates that around 80% of sleep apnea cases in the US are undiagnosed, and a bed partner is often the only person in a position to notice the warning signs the Sleep Foundation lists: loud, frequent snoring, gasping or snorting, pauses in breathing, and daytime sleepiness.
It is also the most effective fix available for the listener. In the Mayo Clinic study above, the intervention that gave spouses an extra hour of sleep was not earplugs or a sound machine. It was treating the snorer. For simple snoring, positional changes, reduced alcohol before bed, and treating nasal congestion help too. Masking sound is what you do to protect your own sleep tonight while that conversation happens.
What does IOn Sleep do for snoring?
IOn Sleep lets you build the kind of layered, low-frequency mix that masks snoring well. You can combine up to three sounds with independent volume, so you can set brown noise as a deep base, add rain for the higher edges, and run it all night. Playback is fully offline, with no streaming dropouts.
A brown noise base with a little rain on top covers the low snore fundamentals and the rattly upper harmonics without pushing either sound loud. Leave the timer off so the mix runs through the late-night hours, and bundled audio with gapless looping means there is no 3am connection drop that suddenly exposes you to the snoring at full contrast. If you wake in the small hours anyway, why you wake up at 3 AM covers the causes that are not acoustic. IOn Sleep is free on Android, with no account required.
The bottom line
Blocking out a partner's snoring is a matching problem. Snoring is low-pitched and intermittent, so the sound that covers it best is low-pitched and continuous: brown or pink noise, played all night, set just loud enough that each snore stops standing out. Foam earplugs, fitted properly, take the edge off the peaks and let the masking sound run quieter.
If the snoring is loud, nightly, and comes with gasping or pauses, stop treating it as your problem to mask. Treating the snorer is the only intervention with evidence behind it for giving the listener back a full hour of sleep.
