These sounds are usually referred to as noise colors and there are three most common types which are white, pink, and brown noise color.

Noise color sounds will help and remove any background noise thanks to the frequency levels used. It will put you to sleep more easily and will make sure you aren’t waking up during the night which is really important.

As you now know that there are three most common color noise sounds. But something you don’t know is how they work.

Also, you don’t need to necessarily sleep to these types of sounds, as they can also help you improve your concentration when needed or just help you relax after a long day of work.

White color noises for sleep

White noise are basically frequencies that are equally flat all the time. It might be hard to understand it, however, after a few examples, you will understand. They are great at removing the background noise which is really helpful during the night.

Waking up in the middle of the night is bad for your sleep since you are stopping the sleeping cycles each time you wake up. For example, a white color noise will help to remove the background noise and help you focus so you can fall asleep more easily while maintaining the sleep.

If your family members are noisy, or your neighbors are slamming their car doors way too early in the morning, white color noise could help you with that. It will remove the background noise and help you stay focused on the white color noise during your good night’s sleep.

• Light sounds of rain
• Hissing steam
• Television static

There are many more examples, and I am sure light sounds of rain is a perfect example to understand the white color noise. Another example which many people will know is the static sound of the television when it’s set on a different frequency than it’s normally used to.

Most likely you get the idea, and you might wonder how does it actually help you to sleep better. Well, some people get sleepy just by listening to the white color noise.

It cancels the surroundings and your brain only focuses on that one particular type of noise. It helps you to concentrate and it will prevent your brain from overthinking things so it will help him relax more easily which leads to better sleep, and also you will be able to fall asleep faster than before.

Pink color noise is similar to the white color noises, however, it works a little bit different. White color noise uses higher frequencies which are equal all the time, while pink color noise uses lower frequencies at higher volumes.

People like to think of pink color noise as a white color noise, just with a bass sound added. It uses lower frequencies, however, it’s usually deeper than white color noise. For everyone who thinks that white color noises are harsh and thin, pink color noise might make them feel better. Pink color uses noises from all the spectrum at lower frequencies which makes the sound deeper and gentler sound.

While white color noise is one of the most known noises for improved sleep, pink color noise has the same benefits. It sounds different, however, it still provides better sleep by helping a person focus. Pink color noise doesn’t need to be used for sleeping purposes. It can be used for focusing on important things during work or studying for example. It also has the ability to alleviate headaches or even sooth babies and young children. Sleep sounds for babies and newborns are proven to help them sleep better.

Sleep sounds for babies and newborns is a common technique practiced by the parents nowadays.

Again, it might be hard to understand the difference between the sounds, and how do they actually work until you learn the examples and listen to them yourself.

• Heavy rain
• Rushing water
• Strong wind through leaves
• Air condition

While they still can cancel the background and benefit your sleep, they can be also used for focusing and relaxing. Heavy rain sounds for sleep and rushing water sounds are great examples, and they provide the difference between white color noises such as light rain sounds for sleep or static television sound.

Also, have you ever noticed how sleepy you get during the car rides on a highway, or train rides? It’s mostly because of the noise car or train produce when driving at the same speed. Although, temperature plays the big part as well. But a car or train consistent sound can be a good example of pink, or even maybe a brown color noise which I will mention later in this post.

Brown noise is the third color from the most common noise colors. It’s also the least researched one

Many people rely on the white or pink color noise, while brown color noise has a lot to offer as well. An interesting fact would be that the brown name doesn’t derive from a color name, yet from a person named Robert Brown. He discovered the Brownian motion that generates brown noise.

Brown color noise is similar to the pink color noise. However, it uses the low-frequency sounds but it takes them even further in order to create a noisy pattern.

It’s might be the reason why not many people like the brown color noise, however, there are still benefits for people who do like it.

Benefits of brown color noise would be better relaxation and meditation, improved focus, increased reading comprehension, and like other color noises, it benefits and improves sleep.

• Rushing water (like waterfalls or ocean waves)
• Low Roar
• Deep Hum
• Clothes Dryer
• Train Passing

You must have heard at least one of the examples, and it might not make sense right now such as how can the train passing be relaxing sounds for sleep, however, you would have to try it out and see for yourself the great benefits.

Usually, the deeper qualities of the noise are, the better they are for relaxation and sleeping purpose.

It’s up to you which type of sound you prefer more, and there isn’t the best or the worst color noise. It’s a matter of the personal preference, and there haven’t been done any studies to prove which type of sound is the most effective simply because of that reason.

Ocean sounds for sleep are a great example of brown color noise.

Sleep machine is a device which produces mostly one or more types of the color noise.

It’s a white noise that people have found it’s the best color noise for improved sleeping. White color noise has the ability to reduce and remove the background noise which benefits and allows people to have a quality good night’s sleep.

Usually, when you’re woken up by a noise in the middle of a night, it’s due to the inconsistency in the same noise. That’s why white noise is good for sleep since it blocks out other inconsistent noises by providing quality consistent background noise which will help you fall asleep faster as well.

Sleep machines are made to produce quality consistent white noise for a better sleep. Although, as I have mentioned sleep machines are mostly made to produce white color noise, however, you will be able to find sleep machines that can produce other types of noise such as pink or brown.

It’s very simple to use a sleep machine as it has only a options to adjust the noise for your personal preference. There is usually a power button with timer included, volume button, and some sleep machines have the option to choose between a fan sound or white color noise.

Fan sound is more likely to be a pink color noise, however, some people can’t fall asleep without the sound of a fan, so that’s why most of the sleep machines come with that option. It’s also a great way to have a sleep machine which is able to produce white and pink color noise.

Overlooked tip – cover the basics with a good  blankie

You can experiement with relaxing sounds for sleeep, but that only covers after you’ve made sure you hav ethe basics covered.

One of the basic is temperature under the blanket – you need to be warm but still allow for breatheability for bodytemperature regulation. If you think this might be a problem for you, you should probably take a look at our guide on best warm winter blankets here.

Active noise canceling headphones or earbuds can do everything passive ones can, however, they have improved structure barriers that block the high-frequency sound waves.

There is a microphone placed inside the earcup which listens to the sounds that can’t be blocked passively, and then it has a little speaker which produces sound waves to block the external sounds. Thanks to the little speaker which produces sound waves, external sound waves can’t disturb our ears.

Although there is a little bit more technology involved in making the active noise canceling headphones, they’re still necessary for people who are battling with high-frequency noises on daily basis.

Also, if you are a regular flier, you might have come to conclusion by yourself that you should probably invest in a good pair of active noise canceling headphones.

Passive canceling headphones are mostly used by the workers who work with machines that produce high-frequency noises, especially inside the room. They use passive canceling headphones not to completely remove the external noise, but mostly to protect their ears from the noise.

Noise canceling earbuds are a great solution if you can’t fall asleep because of the different noises such bed creeks, or birds outside the window.

If you don’t like listening to any kind of noise such as fan sound during your sleep, you could probably help yourself with a good pair of passive earbuds.

Either if you decide to go for active or passive noise canceling headphones or earbuds, investing in one pair is really worth it and can help you sleep better with no noise, and they will also protect your ears from the high-frequency noise.

No matter what’s the reason you can’t sleep – sleep pillow sounds might help you and fix your problems.

Sleep Pillow is an app available on both Android and iOS smartphones, which comes with a lot of sounds specially designed to help you fall asleep faster and sleep better.

Serious sleep disorders might not be solved with the Sound Pillow app, however, if you are simply stressed or can’t sleep in the silence – relaxing sounds of this app will be perfect for you.

There are a lot of different sounds to help you sleep, and you will be able to set the timer as well to stop playing the chosen sound after some period of time. Sounds are expressed through photos, and for example, water sounds will be expressed with a photo of ocean or rain.

It’s mostly about the personal preference, and that’s why the Sleep Pillow is a great app for practicing and experimenting.

In my opinion, ocean sounds for sleep which can be found inside this app, are really great soothing sounds to get a good night’s sleep. However, on the other hand, many people prefer storm and thunderstorm sounds as their soothing sounds.

Before you move on, let Andy explain what to look for

Top Pick Overall – Bose QuietComfort 35 Wireless

A clear picture about the difference

The point rating system we use, translated to star rating would probably paint a better picture. A difference of 20 points is a half a star – more importantly, these ratings include the category of “value for money” so don’t exactly speak about the absolute quality.

No real competition in raw quality

If you take two factors that are subjective out of the equation (user satisfaction & value for money) you get a more accurate picture of just how much better the experience with the Bose products is compared to any other model.

Ratings comparison – Bose QC35 vs. Paww 3:

Best noise cancelling headphones under 100 dollars – Paww WaveSound 3

Fact sheet of the Paww WaveSound 3 Bluetooth Wireless

• Dimensions – 7×3.1×7.9 “
• Weight – approximately 2 lbs
• Includes an adapter for travel (airplane) and a secondary cable – this allows you to hook the headphones to the airplane system and listen to the sound through the headphones without the interruption of the outside noise
• Comes with a carry case – the sturdy carry-case is a nice plus for travel
• Foldable – this is mainly why the pair is so highly rated in the design category. They fold to a small package that’s easy to pack away in a carry-on.
• Micro-USB charging – the pair comes with both re-chargeable batteries and a micro-USB charging port, meaning that you’ll never have to buy batteries for it
• Sturdy construction – the body is solid metal, from what we’ve seen it’s practically indestructible in normal use. This means that if you get this Paww unit, the reason for replacing it in the future is not likely to be any structural defect like it might be with a plastic body.

Main PROs & CONs of the PAWW 3:

PAWW 3 compared to the top set overall

Best noise cancelling headphones under 200 dollars – Audio Technica ANC9 QuietPoint

Sound quality – nothing to write home about

Like with most active noise-cancelling units, the quality of the sound is not stellar…from the balance and depth of the bass to the treble, it’s all sub-par compared to the Bose we mentioned above.

The bottom line is that this Audio Technica pair will be the choice of those who put the noise cancellation above the quality of the sound.

With that side, the ANC9 are still the best affordable noise cancelling headphones under 200 dollars.

Main PROs & CONs of the ANC9:

Honorary mention – CozyPhones Sleep headband with speakers

The CozyPhones feature two thin speakers wrapped in a comfortable, lycra-based headband. We’re stressing the fact lycra here because the main issue with sleep headband speakers is the heat developing underneath the band.

Lycra makes all the difference

With lycra, the issue of heat is a moot point because it breathes much better than materials used in similar headbands, like the SleepPhones.

Talking about the sound is also moot because it’s nothing to write home about, nor are the people that will be interested in a headband concerned with it.
