The importance of sleep cannot be overstated. Yet, more often than not, we do know of someone with sleep issues (and it might even be ourselves). While many factors can be attributed to sleeplessness, one thing is clear; the more sleep-deprived a person becomes, the more physical and mental problems start to crop up.

Putting aside internal factors, for now, we'll be concentrating on minimizing and eliminating the external factors that might just be the sole reason for your sleepless nights. Depending on your location, time, and the activities of others in your vicinity, it can be tough to find (and maintain) the peace and quiet you need for a good rest.

This is where a portable white noise machine comes in handy. It's usually sounds at random frequencies and intensities that disrupt our sleep. Instead of resorting to earplugs or covering your head with a pillow (which is an uncomfortable and unhealthy way to sleep), a white noise machine works by continually emitting sounds at the same intensity to mask other external disruptions.

Other than helping us sleep soundly, a portable white noise machine is also a great addition when studying, working in the office, or while holding a private meeting. Since it helps to “smooth” out the noises in your environment, it acts as a natural and effective sound barrier.  

Your Guide to Choosing the Best Portable White Noise Machine

Just like most things you’ll end up purchasing, your choice for a portable white noise machine should not fall under a one-size-fits-all approach. Over the years, many brands and innovative designs have entered the market, so you have plenty of choices at your disposal. The key to choosing the right portable sound machine for yourself rests in understanding the features provided and your needs.

Important Key Features

  • Variety of fan sounds and white noises - Some portable white noise machines only come with fan sounds (like Marpac’s Dohm Classic), while others offer a choice of other white noises such as rain and ocean sounds and even soothing lullabies for your little ones.
  • Speaker placement and volume range - Depending on the space you intend to cover, the location of your portable white noise machine's speaker plays a paramount role in ensuring adequate coverage. When it comes to volume range, some devices allow for finer adjustments with a knob, while others only provide two to three sound volumes to choose from. 
  • Type of power source required - If you think it's pretty annoying to travel around with a portable white noise machine that requires an AC socket to work, you should consider battery or chargeable options instead. For those intending to travel to other countries or locations without a power socket, this could be a deciding factor. 
  • Auto-off timer - Like other types of electronic equipment, some portable white noise machines come with an auto-off timer. This is especially useful if you only intend to use it for a shorter period and to save power (or electricity). However, if you intend to use it for a longer, fixed duration, this feature might not be necessary at all.  
  • Light availability - Not all portable white noise machines come with a light. However, it can be a handy feature if you intend to place it in a nursery (as a soothing lighted source) or if you'll like to save space by eliminating other placed sources of light.  
Now that you’ve gotten a better idea of just how you should go about selecting the best portable white noise machine for yourself, let’s take a look at some recommended portable white noise machines:

This powerful white noise machine does a great job of masking disturbing external sounds and providing uniformly relaxing sounds. Due to its compact size (measuring 4.4 x 4.4 x 2.2 inches), it’s also a fantastic option if you intend to bring it along on your travels or even for moving about from one location to another.

As you can see, there are only three split buttons available at the front of the machine, thus reducing the headache of fiddling around with it in the dark. Its speakers are placed facing upwards towards the ceiling, allowing for a clearer projection of high fidelity sounds.

Other than regular white noise options, the LectroFan Classic also provides deeper-sounding colors (such as pink and brown noise). These options are essentially white noise, but with reduced higher frequencies that can help to improve your sleeping quality further.

It's an excellent solution for any household or commercial environment and can be powered by either the AC adapter or USB cable it comes with. If you're looking for a portable white noise machine with an auto-off timer, you'll want to consider this one as it offers a timer that can be set for increasing 60-minute intervals with each tap.

Overall, with 10 fan sounds and 10 white noise variations to choose from as well as a decent volume range that can go as high as 85 dB, this travel-friendly white noise machine is a great buy for those looking for a user-friendly, yet comprehensive option.

When it comes to delivering high-quality white noises, you can't go wrong with the super affordable HoMedics Sound Spa. As the official sound conditioner for the National Sleep Foundation, this fantastic portable white noise machine has everything you could want in a budget appliance.

Oftentimes, it's not so much that we're unable to fall asleep or focus on what we're doing, but the annoying distractions that we can't control. Instead of going completely bananas, you can now choose from six digitally recorded ambient sounds: White Noise, Rain, Brook, Thunder, Ocean, and Summer Night. Since you can't stop or control your external environment, you can at least do something on your end.

The Sound Spa is also really lightweight and compact, making it the perfect choice for travel. Another plus point here is that it works perfectly well with the provided adapter or with four AA batteries. Who wants the headache of finding somewhere suitable to plug in their portable white noise machine when they’re traveling, right?

Not only is this white noise machine suitable for adults, but it's a great buy for toddlers and children as well. Whether you're looking for a solution to fall asleep, concentrate on your work or studies, or even meditate, you're bound to find this machine a charm.

With its auto-off timer options for 15, 30, and 60 minutes, you can easily set how long you want your portable white noise machine to run for. This helps to conserve energy and also ensures that it's not in use when it's not needed. Overall, this is a white noise machine you should consider purchasing for your needs.

  • Effectively masks background noise
  • Provides 6 digitally-recorded sounds
  • Compact size (great for traveling and smaller spaces) and lightweight

Also known as the Sleep-Mate, Marpac's Dohm Classic has been around for the longest time (since 1962!), and it's still one of the most reliable and easy-to-use portable white noise machines in the market.

Compared with the LectroFan Classic, this Marpac model is a little larger (at 5.8 x 5.8 x 3.2 inches), but it's still a good compact size that's suitable for all kinds of spaces. In fact, the reason why it's still a popular buy even until today is mainly due to its simple design and functions.

Unlike other portable white noise machines that deliver digitally recorded sounds, the Dohm Classic produces pink noise straight from an internally rotating fan. If you're sensitive to looping sounds, this is a great solution since you'll get to enjoy a natural ambient sound without getting disturbed by actual moving air.

Although the obvious downside to having only two volume options (High or Low) would be that you’ll have to stick to whichever suits your preference best, there’s an almost infinite amount of tones for you to choose from. Simply twist the upper section of your Dohm Classic to fine-tune the tone, and let your body and senses soak into its relaxing sound.
  • Effectively masks background noise
  • Contains less high-frequency sounds (in comparison with other white noise machines in the market)
  • No distracting digital looping
  • User-friendly and straightforward design (just twist to adjust)
  • 101 trial nights
  • 6 ft AC adapter plug (comfortable length)
  • Compact size (great for traveling and smaller spaces)
  • Available in many colors (white, black, gray, camo, tan, and pink) 

  • Users need to use an AC power socket for it to work
  • Only provides two volume options

The Hatch Baby Rest is more than just a portable white noise machine. Other than providing soothing sounds, this sleek and modern machine also doubles as a night light and has a time-to-rise function.

Unlike a majority of other white noise machines out there, this fantastic machine comes with an adult-friendly app. This means that you'll be able to adjust and preset the sounds, volume, light color and intensity, and time-to-rise for your child. The best part about it is that you'll be in complete control of the Rest without having to worry about your child changing its settings.

It’s been scientifically proven that certain light colors contribute to healthy circadian rhythms (for anyone) and the production of melatonin (which helps prepare our bodies for sleep). Coupled with the choice of nine ambient white noises and three lullaby selections, you can rest assured that your child will soon fall fast asleep.

Once your child gets a little older, it’s time to utilize the time-to-rise alert function. Instead of going to your child’s room to wake them up every single day, the Rest can easily let them know when to wake up. This promotes your child’s independence and frees up your time to attend to other matters.

The Rest is one of the best portable white noise machines in the market for babies and younger children. For those looking for additional features, there is a more advanced version available (Rest+), but that also comes with a heftier price tag.

  • Additional night light feature (with customizable colors and brightness levels)
  • Effectively masks background noise
  • Features time-to-rise alert
  • 3 ways to control: manual activation, program to turn on automatically or adjusted remotely with an app
  • Compact size (great for traveling and smaller spaces)
  • Comes with toddler-lock
  • Sleek and modern design
  • Does not get hot (safe for children)
  • Great coverlet designs can be purchased separately

  • Needs to be plugged in to work
  • App needs to be near Hatch Baby as it connects via Bluetooth

One of the perpetual annoyances of most electronic appliances is really their dependence on a wired power source. After all, who wants their space to feel and look cluttered up with various types of wires?

This is where Big Red Rooster’s white noise machine scores a goal. Even though an adapter is provided with your purchase, you have the choice to use 3 AA batteries instead. With this, you won’t have to get an additional international adapter when you travel overseas since you won’t need one. 

Rather than having your portable white noise machine turned on for the entire duration of your sleep, you also have the option of setting your auto-off timer to 15, 30, or 60 minutes instead. This way, your batteries will last a whole lot longer. If you're using the provided adapter, you can also lighten your electricity bill.

Big Red Rooster's machine doesn't provide a ton of white noise choices (just six), but that's enough for most people. There's a dedicated labeled button for each sound, making it perfect for fast and easy selection.

  • 6 ambient sleep sounds to choose from
  • Effectively masks background noise
  • Can be turned on the entire time or set to turn off with a timer
  • 2 power options: adapter or 3 AA batteries
  • Compact size (great for traveling and smaller spaces) and lightweight

  • Turns on at full volume (can be quite disturbing for others who are already asleep or occupied with something)
  • Button sounds are quite loud

Out of all the portable white noise machines reviewed here, Dreamegg's D1 Pro packs the most variety of sounds in its compact, streamlined case. With a total of 29 high fidelity sounds (7 white noise sounds, 7 fan sounds, and 15 natural sounds), there's bound to be something that suits your preferences and needs.

Unlike some other white noise machines, the D1 Pro also provides an auto-off timer. Instead of leaving it on for an unnecessary period, you can now set it to off after 30, 60, or 90 minutes instead.

Designed with parents of young children and babies in mind, the D1 Pro combines the soothing sounds conducive to restful sleep, a calming night light, and also serves as a noisemaker to mask disruptive sounds. Since it comes with an internal rechargeable battery (either by adapter or USB cable), you'll be able to place it anywhere you like without having to worry about having a power socket close by.

In case you think that's all there is to the D1 Pro, just wait. Not only does it pack a whopping 29 types of sounds, but there are also 32 volume levels to choose from. Now that's a lot of options for something so small. Last but not least, this portable white noise machine also remembers your last setting so you won't have to keep fiddling with the buttons in the dark too.

Our last contender in the portable white noise machine series is another Marpac favorite: the Yogasleep Rohm. Weighing in at a mere 3.8 oz, this incredibly lightweight white noise machine is our pick for the most compact and travel-friendly option.

However, don't expect to get a ton of noise options from this portable white noise machine. It comes with 3 soothing sounds: gentle surf, bright white noise, and deep white noise. If you're looking for a basic (and most importantly, compact) white noise machine, this is it.

You can easily fit it into your bag or luggage, and it also comes with a durable lanyard, making it easy to handle or hang just about anywhere. Once fully charged (with a USB cable), you can use the Yogasleep Rohm for an entire night without worries.

For such a small white noise machine, you might think its volume options would be lacking, but since it ranges from 0 to 85 dB, you’re definitely covered on that front. To adjust the volume, just push the button to set it accordingly.

  • Has 3 soothing sounds to choose from
  • Effectively masks background noise
  • Compact size (great for traveling and smaller spaces) and lightweight
  • Can easily be handled and hanged as it comes with a lanyard
  • Operates a whole night on a single full charge
  • Comes with a 1-year limited warranty

  • Does not come with a timer option
  • Has to be charged regularly as battery life is quite short

At the end of the day, you'll want to first determine your reasons for a white noise machine. Some people use it exclusively to sleep, others to mask noises at work or while studying, and even to manage tinnitus. Whatever your reasons are, you can rest assured that there will be something suitable for you.
