Pink Noise Machine FAQ

What Does Pink Noise Do?

Both white and pink noise are members of an entire color family of sound, including brown and black noise. Sounds are assigned these colors based on how energy is distributed over several frequencies.

For example, white noise is composed of energy that is equally distributed across audible frequencies. But brown noise, on the other hand, also known as red noise consists of higher energies at lower frequencies such as deep, roaring sounds and thunder.

Pink noise is deeper than white noise energy in that it includes all audible frequencies, but energy is not distributed equally among them.

The energy of pink noise is greater at lower frequencies and decreases as the frequency rises. Therefore it has a distinct sound that is much deeper than white noise.

So if you prefer listening to ocean sounds at bedtime, then you actually prefer pink noise.

Many sleepers believe that white noise does the best job of masking any form of noise pollution, such as a garbage truck lumbering up at 6 AM or a neighbor’s barking dog at midnight, the fact is white noise is evenly distributed across the frequencies effectively blocking out sounds that may disrupt your sleep.

However, studies have shown that these low-frequency sounds, such as pink noise soothe the brain by actually reducing brain waves, which helps to induce a superior quality of sleep.

So, according to experts who published a 2012 study on pink noise, it has been concluded that pink noise reduces brain wave complexity and induces more stable sleep time, therefore, improving the quality of sleep.

Which Color Noise Is Best For Sleep?

Using White Noise Machine

It’s highly likely that you’ve heard of white noise. It’s often associated with a common static-like sound pattern added to alarm clocks and sleep aids in the market known as white noise machines. However, there are more colors of noise to the spectrum.

So ultimately, white noise is made up of random and equal amounts of frequencies from the entire sound spectrum. This is why it’s effective in masking just about every external sound.

It works because research has discovered that the human ear can only process a given number of frequencies at the same time.

Therefore white noise machines are designed to create some patterns utilizing all available frequencies. So some of the common benefits of white noise are that it improves concentration and promotes sleep.

Some listeners do, however, find that white noise is too high pitched. And they may prefer pink noise, which is like noise however operates on a lower frequency and creates a deeper and more gentle sound.

So ultimately, pink noise can be compared to the sounds of rushing water, strong wind moving through dry leaves, and heavy rain.

The sound is more subdued, deeper, and offers the same benefits of white noise because it also eliminates background sounds.

So ultimately, pink noise improves focus, gives you relief from headaches, soothes babies, and offers better sleep for the entire family.

Ultimately, lots of people have been noting that brown noise is probably the best for inducing sleep.

Brown noise also known as red noise takes the low-frequency emphasis of pink noise a step further by creating a noise pattern that is closer to a buzzing or humming rather than hissing.

Brown noise is often compared to rushing water and has a hum similar to a clothes dryer or a passing train.

The deeper qualities of the sound are great for relaxing and inducing sleep.

Ultimately, brown noise has been known to be extremely effective in relaxation and meditation, improving focus, increasing the reading comprehension, and giving you overall better quality of sleep.

What Is An Example Of Pink Noise?

Sound Wave Of Pink Noise

Pink noise is a variation of white noise. However, with pink noise, there’s power in the low-frequency bands, so there is a lot of bass added to it.

Pink noise sounds a lot like humming or soft static. So try to imagine waves crashing, a train chugging along, or rain falling and you’ve got pink noise.

Aside from the pink noise that can be found online, there are physical devices that you can use to listen to while you sleep.

However, the type of pink noise used in lab settings or studies are administered in a specific type of way. So the pink noise you come across online may not be exactly the same thing.

Can All White Noise Machines Produce Pink Noises?

White noise has been soothing people off to sleep for ages. It basically encompasses all of the frequencies any person can possibly hear and has the potential to drown out outside sounds.

Ultimately, the consistency of white noise creates a true masking effect which ultimately helps people fall asleep faster.

White noise has been so effective in helping people to sleep over the years that it has led to the development of sound machines. These sound machines are capable of playing white noises to help you focus, relax and fall to sleep.

Lately, though, pink noise has become the darling of all sleep sounds. This is probably because research has suggested an increase in time spent in deep sleep and enhanced memory when listening to pink noise.

Pink noise is a mix of high and low frequencies like the sound of gentle ocean waves or falling rain, so it is very soft and calming. Most sound machines these days have the ability to play both white and pink noise.


So ultimately the truth is no one really knows which sound is the best for inducing sleep and relaxation.

The truth is, while white noise, pink noise and brown noise are all proven to be effective in helping people to get rest and relaxation, ultimately it’s hard to tell which is the best.

For some people, white noise has consistently helped them to fall asleep and stay asleep for years.

Others are firm believers that pink noise is more calming and soothing while there are those that are firm supporters of brown noise.

So basically once you find a sound that you like and has consistently helped you fall asleep, consider buying a sound machine that offers various types of sounds to choose from.

These machines are recommended since they offer far higher definition sound and are able to play louder volumes than a phone.
