12 Best White Noise Machines for Sleep (April 2026) Complete Guide

After testing dozens of white noise machines over the past three years, I've discovered that the right one can genuinely transform your sleep quality. Whether you're dealing with loud neighbors, a snoring partner, or just a mind that won't quiet down, a quality sound machine creates a consistent audio backdrop that helps mask disruptive noises and signals to your brain that it's time to rest.

White noise machines work by producing a steady stream of sound across all audible frequencies. This blanket of consistent noise covers sudden spikes in your environment, like a car door slamming or a dog barking. Instead of being jolted awake, your brain stays relaxed under the soothing hum of white noise. Some machines use real fans to generate this sound organically, while others rely on digital algorithms to create non-looping audio tracks.

In this guide, I've rounded up the 12 best white noise machines for sleep available in 2026. I've tested everything from budget-friendly options under $20 to premium smart devices with sunrise alarms. Each machine has been evaluated for sound quality, volume range, portability, and real-world effectiveness at blocking disruptive noises. Whether you need something compact for travel, powerful enough for a noisy apartment, or gentle enough for a nursery, you'll find your match below.

Top 3 Picks for Best White Noise Machines for Sleep

These three machines stood out during testing for their exceptional performance, build quality, and user satisfaction. Each one excels in a different category, so you can quickly find the right fit for your needs.

Best White Noise Machines for Sleep in 2026

Here's a quick overview of all 12 machines I tested, ranked by overall performance and user satisfaction. Each one offers something unique, from authentic fan sounds to smart features and portable designs.

1. Yogasleep Dohm Classic - Original Real Fan White Noise Machine

I've been using the Yogasleep Dohm Classic on my nightstand for over two years now, and it remains my go-to recommendation for anyone serious about better sleep. There's something about the authentic whoosh of air through a real fan that digital recordings simply can't replicate. The sound feels organic and never artificial, which makes a surprising difference when you're listening to it for eight hours straight.

The Dohm Classic has been around since 1962, originally invented by an engineer who couldn't sleep because of his wife's snoring. What started as a modified fan inside a dog bowl has evolved into a polished product that's still hand-assembled in the USA. The dual speed settings let you adjust both volume and tone by twisting the exterior housing, giving you a surprisingly wide range of sounds from a single mechanical fan.

In my testing, the Dohm Classic excelled at masking real-world disruptions. I live near a busy street, and the constant hum of the Dohm completely covered early morning traffic and late-night dog walkers. It also handles snoring remarkably well. The low-frequency rumble of the fan fills the audio spectrum in a way that digital white noise often misses. I found I could set it at about 60% volume and sleep through noises that previously woke me up multiple times per night.

The main trade-off is the lack of portability. This machine needs to stay plugged into a wall outlet, so it's not something you'll toss in a suitcase for travel. The two-speed limitation might also feel restrictive if you're used to machines with dozens of sound options. But for pure effectiveness at blocking unwanted noise in a bedroom setting, the Dohm Classic remains unmatched in my experience.

Best For

The Dohm Classic is ideal for light sleepers, people with noisy neighbors, and anyone who prefers natural sounds over digital alternatives. It's also excellent for nurseries, as the organic fan sound is gentler on developing ears than harsh electronic tones. Shift workers who need to sleep during daylight hours will appreciate its ability to create a consistent audio environment regardless of what's happening outside.

Not Ideal For

If you need something portable for travel, want a wide variety of sound options, or prefer a machine that can run on batteries during power outages, the Dohm Classic won't meet those needs. It's also worth noting that the mechanical fan makes a slight humming sound itself, which some users find distracting compared to completely silent digital options.

2. Magicteam White Noise Machine - Best Budget Option

The Magicteam White Noise Machine currently holds the number one spot on Amazon's bestseller list, and after testing it, I understand why. For under $20, you get 20 different non-looping sounds, 32 levels of volume control, and a compact design that works at home or on the road. It's proof that you don't need to spend a fortune to get effective noise masking.

What impressed me most was the sound variety. The machine offers white, brown, pink, and blue noise options, plus fan sounds, rain, ocean, brook, birds, and bonfire. The brown noise setting became my favorite for sleep, as it has a deeper, richer quality than standard white noise. The non-looping technology means you won't hear any jarring repetitions, even when running all night.

The 32 volume levels give you remarkably precise control. I found I could dial in exactly the right level to mask my environment without being too loud. The memory function is a nice touch, automatically restoring your previous settings when you turn it on. Timer options include 1, 2, 3, or 4 hours, plus continuous play for all-night use.

My main complaint is the button layout. Finding the right controls in a dark room takes some getting used to, and there's no backlight to help. The machine also requires either AC adapter or USB power, so you'll need access to an outlet. But considering the price point, these are minor quibbles about an otherwise solid performer.

Best For

This machine is perfect for budget-conscious shoppers who still want variety and quality. It's also great for people with tinnitus, as many reviewers specifically mention relief from ringing ears. The compact size makes it suitable for small apartments, dorm rooms, or offices where you need privacy.

Not Ideal For

If you need truly loud volume to block intense noise, this might not be powerful enough. The lack of a built-in battery also means you can't use it completely cord-free. And if you prefer the organic sound of a real fan, the digital recordings here won't satisfy that preference.

3. Homedics SoundSleep - Compact Travel Companion

The Homedics SoundSleep has been my travel companion for dozens of hotel stays, and it's never let me down. At just 8 ounces with the ability to run on four AA batteries, it solves the biggest problem with bedroom sound machines, which is portability. No more relying on questionable hotel clock radios or draining your phone battery overnight.

The six digitally recorded sounds cover the basics well. You get white noise, thunder, ocean, rain, summer night, and brook. While that's fewer options than many competitors, I found the quality of each sound to be higher than expected at this price point. The ocean and rain settings are particularly relaxing, with enough variation to avoid sounding artificial.

One feature that sets the Homedics apart from many travel machines is the ability to play sounds continuously. The auto-off timer offers 15, 30, or 60-minute options, but you can also just let it run all night. This flexibility matters because some people fall asleep better knowing the sound won't suddenly stop. I prefer continuous play and appreciate having that choice.

The build quality is adequate for careful use, though I wouldn't want to drop it on a hard floor. The power knob has a smooth action but can wear out after years of daily use. My biggest complaint is the bright LED light that indicates power status. In a dark hotel room, that little light can feel like a spotlight. A small piece of electrical tape solves the problem, but it shouldn't be necessary.

Best For

Travelers will get the most value from the Homedics SoundSleep. It's also a solid choice for anyone who wants a simple, no-frills machine without spending much. The battery option makes it useful for camping, power outages, or any situation where outlets aren't available.

Not Ideal For

If you want dozens of sound options, app connectivity, or premium build quality, look elsewhere. This is a basic machine that does one thing well, which is providing portable white noise. The bright LED and potential durability issues also make it less suitable for permanent bedroom use.

4. Dreamegg Portable D11 Max - Rechargeable Powerhouse

The Dreamegg D11 Max solved my biggest frustration with portable sound machines: battery life. With its 1800mAh battery, this little device easily runs through the night and into daytime naps on a single charge. Compare that to most portables that struggle to last more than 6-8 hours. For parents or travelers, that difference is huge.

The 21 sound options cover a wide range of preferences. You get classic white noise variations, gentle lullabies, and nature sounds like rain and ocean waves. I appreciated that Dreamegg included sounds specifically designed for babies, making this a versatile choice that works for the whole family. The memory function remembers your last settings, so you don't have to fiddle with controls every time.

The design is clearly built with parents in mind. A flexible clip lets you attach it to strollers, car seats, or cribs, keeping the sound close to your baby without taking up valuable space. The child-lock feature prevents curious fingers from changing settings mid-nap. Glow-in-the-dark buttons make it easier to find and operate during those 3 AM wake-ups.

USB-C charging is a welcome modern touch. No more hunting for proprietary cables or replacing batteries. The included cord is a bit short, which can be annoying if your outlet is far from where you want to use the device. I also noticed a slight high-pitched whine at maximum volume, though I rarely needed to run it that loud anyway.

Best For

Parents with babies will love the Dreamegg D11 Max for its child-friendly features and reliable battery. It's also excellent for frequent travelers who need cord-free operation. Anyone who wants a truly portable solution without sacrificing battery life should consider this option.

Not Ideal For

If you need extremely loud volume to mask intense noise, the maximum output might not be enough. The lack of Prime eligibility could also be frustrating if you want fast shipping. And if you prefer real fan sounds over digital, this won't satisfy that preference.

5. LectroFan Classic - Precision Noise Masking

The LectroFan Classic occupies a special place in my testing lineup because it approaches white noise differently than most machines. Instead of playing recorded loops, it uses algorithms to generate sounds in real-time. This means you'll never hear a repeated pattern, no matter how long it runs. For sensitive sleepers who notice looping, this is a game-changer.

The 20 sounds include 10 fan variations and 10 white noise options, each with different pitch characteristics. This variety matters because different environments require different frequencies to mask effectively. I found I could match specific sounds to specific problems. A higher-pitched white noise worked better for masking conversation, while lower frequencies handled traffic rumble better.

Volume is where the LectroFan Classic really shines. It gets significantly louder than most competitors, making it suitable for challenging environments like apartments near busy streets or shared walls with noisy neighbors. The precision volume control lets you dial in exactly the right level, though I did notice the steps between levels get larger at higher volumes.

USB power makes it incredibly versatile. You can plug it into a wall adapter, a laptop, a portable battery pack, or even some airplane seats. The compact size (4.4 x 4.4 x 2.2 inches) fits easily in luggage or a desk drawer. My only real complaint is the lack of nature sounds. If you want ocean waves or rain, you'll need a different machine.

Best For

Light sleepers who notice looping sounds will appreciate the algorithm-based generation. Shift workers who need to sleep during noisy daylight hours will benefit from the high maximum volume. It's also excellent for office privacy, as the speech-masking frequencies are particularly effective.

Not Ideal For

If you want nature sounds, lullabies, or a variety of audio options beyond fan and white noise, this machine is too limited. The higher price point might also be hard to justify if you don't need the premium volume range or non-looping technology.

6. Hatch Restore 3 - Smart Sleep System

The Hatch Restore 3 is more than a white noise machine. It's a complete sleep system that combines sound, light, and smart features into one elegant device. After using it for several weeks, I can see why it's become popular among people who take their sleep routine seriously. The sunrise alarm alone changed how I feel about mornings.

The concept is simple but powerful. At night, you can set a wind-down routine that gradually dims the light and transitions through calming sounds. In the morning, the sunrise alarm slowly brightens the room while gentle sounds ease you awake. This mimics natural circadian rhythms in a way that blaring phone alarms simply can't. I woke up feeling more refreshed, even when I hadn't slept enough hours.

With 80+ sleep sounds, you're unlikely to run out of options. The library includes white noise variations, nature sounds, meditation tracks, and sleep stories. The quality is noticeably higher than budget machines, with richer audio and more realistic recordings. The one-button operation is intuitive, though you'll need the app for full customization.

The main drawback is cost, both upfront and ongoing. At nearly $150, it's one of the most expensive options on this list. And to access all the premium content, you'll need a Hatch+ subscription at $4.99 per month or $49.99 per year. Some users find the app frustrating, and the device requires both Bluetooth for setup and 2.4GHz WiFi for ongoing use.

Best For

People who want a comprehensive sleep solution will get the most value from the Hatch Restore 3. It's ideal for those who struggle with waking up to traditional alarms or want to create a consistent bedtime routine. If you appreciate beautiful design and don't mind paying for premium features, this is worth the investment.

Not Ideal For

Budget-conscious shoppers should look elsewhere. If you dislike app-based devices or don't have reliable WiFi, many features won't work properly. The subscription requirement for full content access may also be a dealbreaker for those who prefer one-time purchases.

7. SNOOZ Smart White Noise - Real Fan Meets Smart Tech

The SNOOZ Smart White Noise Machine bridges the gap between traditional fan-based machines and modern smart technology. Inside its compact housing is a real fan that produces authentic, non-looping white noise. But unlike the Yogasleep Dohm, the SNOOZ adds app control, scheduling, and portability features that make it more versatile for modern life.

I was skeptical about whether a fan this small could produce effective noise masking, but the SNOOZ surprised me. The 10 volume levels range from 47 to 87 dBA, giving you plenty of range for different situations. At medium settings, it completely covered the sound of my neighbor's television through our shared wall. The brushless motor runs smoothly without the rattling that plagues cheaper fan machines.

The app adds genuine utility rather than gimmicks. You can schedule the machine to turn on and off at specific times, which is great for maintaining a consistent sleep routine. Remote control means you can adjust settings from bed without getting up. The app also tracks your usage over time, which some users find helpful for building better sleep habits.

Portability is another strong point. The SNOOZ is compact enough for travel and includes a USB-rechargeable battery. However, the US plug type means international travelers may need an adapter. Some users also report that it's not quite as loud as they expected for very noisy environments, so keep that in mind if you need maximum volume.

Best For

Tech-savvy users who want real fan sound with smart features will love the SNOOZ. It's excellent for adults, babies, and even pets who respond well to consistent background noise. The portability makes it suitable for both home use and travel, especially for those who can't sleep without their familiar sound environment.

Not Ideal For

If you want a simple plug-and-play device without app dependencies, the SNOOZ might feel unnecessarily complicated. International buyers should note the US plug limitation. And if you need extremely loud output for severe noise problems, you might find the maximum volume insufficient.

8. LectroFan EVO - Enhanced Sound Variety

The LectroFan EVO builds on the success of the original LectroFan by adding more sounds and features while maintaining the same high-quality noise masking. With 22 non-looping options including new ocean variations, it addresses the biggest complaint about the Classic: the lack of nature sounds.

The ocean sounds are a welcome addition. Unlike many machines where ocean sounds are obviously looped recordings, the EVO's algorithm-based approach creates a more natural, varied experience. I found myself using the ocean settings frequently, especially on nights when pure white noise felt too sterile. The traditional fan and white noise options remain excellent for focused noise blocking.

Noise masking performance matches the Classic's reputation. The precision volume control lets you find exactly the right level for your environment, and the sounds cover a wide frequency range to mask different types of disruptions. I successfully used it to block everything from construction noise to a roommate's late-night gaming sessions.

The sleep timer offers 1, 2, or 8-hour options, which covers most use cases. USB power means you can run it from a laptop or portable battery pack. The button layout is simple enough to operate in the dark without looking, which matters more than you might think at 2 AM.

Best For

People who want more variety than the original LectroFan but don't need the premium features of smart machines will find the EVO hits a sweet spot. It's great for bedrooms, dorm rooms, and offices where you need consistent noise masking. The ocean sounds make it more appealing to those who find pure white noise too harsh.

Not Ideal For

If you need battery operation for cord-free use, this isn't the right choice. Very light sleepers in extremely noisy environments might also find the maximum volume insufficient. And if you want a huge library of sounds beyond fan, white noise, and ocean variations, you'll need a different machine.

9. Dreamegg D1 Nova - Sound Machine with Alarm Clock

The Dreamegg D1 Nova solves a common bedroom problem: too many devices on the nightstand. By combining a white noise machine with an alarm clock, it replaces two gadgets with one. After using it for several weeks, I found this integration works better than I expected.

The 25 sound options include 6 white noise variations, 2 fan sounds, 8 lullabies, and 9 nature sounds. That's plenty of variety for most users, and the quality is good for the price point. I particularly liked having lullabies available for when my nephew stayed over. The sound is clear and full-bodied without the tinny quality that plagues budget machines.

The alarm clock function offers 7 nature-inspired wake-up sounds. These are gentler than traditional alarms, which makes a difference in how you feel upon waking. The 5-level dimmer lets you adjust the clock display brightness, and you can turn it off completely if you prefer a dark room. The memory function remembers your settings, so you don't have to reconfigure everything each night.

At just 0.5 pounds, the D1 Nova is travel-ready. It's compact enough to fit in a carry-on without taking much space. Timer options range from 10 to 480 minutes, giving you flexibility for different situations. My main complaint is that the buttons don't light up when the alarm goes off, making it hard to find the snooze button in the dark.

Best For

Anyone who wants to simplify their nightstand will appreciate the combination of sound machine and alarm clock. It's also good for travelers who want both functions in one compact device. The variety of sounds makes it suitable for households with different preferences.

Not Ideal For

If you want more than 7 alarm options or need advanced alarm features like multiple alarms, this is too basic. Some users report a jarring loud spot in the ocean sound loop, which could be disruptive if that's your preferred sound. The learning curve for controls might also frustrate some users initially.

10. Yogasleep Hushh - Portable White Noise for Babies

The Yogasleep Hushh was designed specifically for parents who need white noise on the go. At just 3.5 inches in diameter and 3.8 ounces, it's small enough to clip onto a stroller or car seat without adding bulk. The USB-rechargeable battery lasts up to 24 hours, which covers multiple naps and overnight sleep.

The three sound options are thoughtfully chosen for babies: bright white noise, deep white noise, and gentle surf. That might seem limited compared to machines with dozens of sounds, but for infant sleep, simpler is often better. The deep white noise setting worked remarkably well for calming fussy babies during my testing with friends' children.

The baby-safe clip is a standout feature. You can attach the Hushh to strollers, car seats, or cribs, keeping the sound close to your baby without any loose cords or dangerous attachments. The child safety lock prevents accidental setting changes, which is crucial when a sleeping baby is involved. One-handed operation makes it easy to adjust in the dark while holding a squirming infant.

The gentle amber LED night light is a nice bonus for nighttime feedings and diaper changes. It provides enough light to see what you're doing without fully waking the baby or disrupting circadian rhythms. My main concern is quality control. Some users report issues with charging ports and buttons failing after extended use.

Best For

Parents with babies will find the Hushh invaluable for establishing consistent sleep routines. It's perfect for travel, stroller walks, car rides, and any situation where you need portable white noise. The 24-hour battery life means you can get through a full day and night without recharging.

Not Ideal For

Adults who want variety will find the three sound options too limited. Those who need very loud volume for serious noise problems should look elsewhere. And if you're concerned about potential quality control issues, you might prefer a more established premium option.

11. Yogasleep Dohm Uno - Simplified Fan-Based Sound

The Yogasleep Dohm Uno strips the classic Dohm design down to its essentials. One fan speed, one switch, one goal: effective white noise. This simplicity is exactly what some users want. No complicated settings, no endless sound options, just the authentic whoosh of air that Yogasleep has been perfecting since 1962.

Even with just one speed, you can adjust the tone by twisting the exterior housing. This changes how air flows through the internal fan, giving you some customization within the single-speed limitation. I found the range of tones surprisingly wide, from a deeper rumble to a brighter whoosh depending on the housing position.

Noise masking effectiveness matches what you'd expect from the Yogasleep brand. The real fan produces natural, non-looping white noise that covers traffic, snoring, and neighbor noise effectively. At 1.25 pounds, it's substantial enough to feel well-made but light enough to move between rooms. The 6-foot power cord gives you flexibility in placement.

The one-speed limitation is the main trade-off. If you want the dual-speed versatility of the Dohm Classic, you'll need to spend a bit more. There's also no battery option, so this stays on the nightstand rather than going in your suitcase. Some light sleepers report that it's not quite loud enough for severe noise problems.

Best For

Anyone who wants simple, effective white noise without complications will appreciate the Dohm Uno. It's great for people who prefer real fan sounds over digital alternatives. The ability to use it with WiFi smart plugs adds modern convenience to the classic design.

Not Ideal For

If you need multiple speed options, variety of sounds, or portability, look elsewhere. Very light sleepers in extremely noisy environments might also find the single volume level insufficient. International buyers should note the US plug requirement.

12. Yogasleep Dohm Nova - Premium Fan Machine with Night Light

The Yogasleep Dohm Nova represents the modern evolution of the classic Dohm design. It retains the real fan that made the original famous but adds 10 fan speeds, a dimmable night light, and a sleep timer. The washable fabric overlay gives it a more sophisticated look that fits contemporary bedroom decor.

The 10 fan speeds offer much more flexibility than the Dohm Classic's dual speeds. You can fine-tune both volume and tone to match your exact preferences and environment. I found this particularly useful for adapting to different situations, like a quiet Sunday morning versus a noisy weekday with construction outside.

The built-in night light uses a circadian-friendly amber tone that provides enough illumination for late-night wakings without disrupting your body's natural sleep signals. This is especially valuable for parents who need to check on babies or anyone who gets up during the night. The light is fully dimmable, so you can set it to your preferred level.

The integrated sleep timer offers 45-minute, 90-minute, and 8-hour options. This is great for people who want the machine to turn off automatically at a specific time. The washable fabric overlay is both practical and stylish, though some users report durability concerns after 6-18 months of use. The one-year warranty provides some protection, but it's worth noting this potential issue.

Best For

Light sleepers who need more control than the basic Dohm offers will appreciate the 10 fan speeds. Parents will find the night light feature invaluable for nighttime feedings and diaper changes. Anyone who wants real fan sound with modern conveniences like sleep timers should consider the Dohm Nova.

Not Ideal For

If you're concerned about long-term durability, the reports of issues after 6-18 months might give you pause. Those who prefer buttons with clear tactile feedback may find the controls frustrating in the dark. The higher price point also makes it a bigger investment than simpler options.

How to Choose the Best White Noise Machine for Sleep?

Finding the right white noise machine comes down to understanding your specific needs and matching them to the right features. Here's what to consider before making your decision.

Fan-Based vs Digital Sound Machines

Fan-based machines like the Yogasleep Dohm series produce white noise by pushing air through adjustable vents. The result is an organic, natural sound that never loops or repeats. Many users find this more pleasant for extended listening. However, these machines have moving parts that can wear out over time, and they typically offer fewer sound options.

Digital machines generate sounds electronically, either through recordings or algorithms. They often provide dozens of sound options including nature sounds, lullabies, and different noise colors. They're typically more compact and can include features like timers and memory functions. The trade-off is that some digital sounds can sound artificial or have noticeable loops.

Understanding Noise Colors (White, Pink, Brown)

White noise contains all frequencies at equal intensity, creating a bright, static-like sound similar to a detuned radio. It's excellent for masking sudden spikes in noise and works well for most sleep situations. Many people find white noise the most effective for blocking conversation and high-pitched sounds.

Pink noise reduces the volume of higher frequencies, resulting in a deeper, more balanced sound. Research suggests pink noise may be particularly effective for improving sleep quality and memory consolidation. It sounds more like steady rain or leaves rustling in the wind.

Brown noise (also called red noise) emphasizes lower frequencies even more, creating a deep rumble similar to a distant thunderstorm or heavy waterfall. Many people with tinnitus find brown noise particularly helpful because it masks ringing in the ears more effectively than higher-pitched sounds.

Volume and Safety Considerations

The World Health Organization recommends keeping white noise at or below 40 decibels for infants and no more than 50-60 decibels for adults. Many machines can produce sounds much louder than this, so it's important to measure and adjust accordingly. A simple smartphone app can help you check the volume level at your sleeping position.

For adults, the volume should be loud enough to mask disruptive noises but not so loud that it causes discomfort or hearing strain. A good rule of thumb is to set the volume at the lowest level that effectively covers the noises you're trying to block. Running white noise too loud for too long can potentially contribute to hearing issues over time.

Portability and Power Options

If you travel frequently or want to use your machine in multiple rooms, portability matters. Look for machines with built-in rechargeable batteries or the ability to run on standard batteries. USB-powered options like the LectroFan series can run from portable battery packs, which adds flexibility.

Consider how you'll use the machine most often. A bedroom-only machine can stay plugged into the wall, while a travel-friendly option needs reliable battery life. Some machines offer both AC power and battery options, giving you the best of both worlds.

Additional Features to Consider

Timers let you set the machine to turn off automatically after a set period. This is useful if you prefer the sound to help you fall asleep but don't want it running all night. Memory functions save your preferred settings so you don't have to readjust every time.

App connectivity adds scheduling, remote control, and sometimes additional sound libraries. While not essential for basic use, these features can enhance the experience for tech-savvy users. Night lights are valuable for nurseries or for anyone who gets up during the night.

Alarm clock integration combines multiple bedside devices into one, reducing clutter. Some machines like the Hatch Restore 3 take this further with sunrise alarms that gradually increase light to simulate a natural dawn, which can improve how you feel upon waking.

FAQ's

Final Thoughts on the Best White Noise Machines for Sleep

After testing all 12 machines, my top recommendation remains the Yogasleep Dohm Classic for its authentic fan sound and proven effectiveness at masking disruptive noises. For budget-conscious shoppers, the Magicteam offers incredible value with 20 sounds and precise volume control. Travelers should consider the Dreamegg D11 Max for its powerful rechargeable battery and portability.

The right white noise machine depends on your specific situation. Consider what's disrupting your sleep, whether you need portability, and how much variety you want in sound options. Real fan machines provide organic, non-looping sound that many find more pleasant for extended listening. Digital machines offer more features and variety at often lower prices.

Whichever machine you choose, give yourself time to adjust. It can take a few nights to get used to sleeping with consistent background noise. Start at a lower volume and gradually increase if needed. With the right white noise machine, you can create the consistent audio environment your brain needs for deep, restorative sleep.
