Our Pink Noise

As with the colors of light, each of the colors in the noise frequency spectrum is distinctly different and lends its unique properties to

specific functions. In the case of sleep, colored noise is often used to tune out background noise (think noisyneighbors or city noise.

It is also used to tune out “not so background” noise such as  a snoring partner or nieghbors that party like it’s New Years Eve every weekend.


With Pink Noise in particular, it is also used to promote deep sleep.Pink Noise is a steady sound that filters out distracting or obtrusive noises. Similar to the more familiar White Noise, Pink Noise employs deeper tones and lower soundwaves which produce a soothing, more relaxing sound than White Noise.


The color of noise is determined by the energy of the sound signal. Specifically, it depends on how energy is distributed over various frequencies - or the speed of sound. White Noise consists of all frequencies we can hear, each at an equal energy level.


Pink Noise also consists of all frequencies we can hear, but the energy isn’t equally distributed across them; it’s more intense at


What is Pink Noise?

Pink Noise in Nature

lower frequencies, which creates a deeper, more pleasant sound. It’s now wonder Pink Noise is all the rage these days. Many, many people have discovered how Pink Noise helps them relax and get the sleep they so desperately need.

Nature is full of Pink Noise, including leaves rustling in trees, steady soft rain or a light breeze, to name just a few.


To the human ear, Pink Noise sounds even, and because it has the same tones in nature that we find pleasant, many people find Pink Noise very relaxing as well.


In fact, customers often tell us they would still use SoundOff’s Pink Noise to fall asleep even if their partner stopped snoring tomorrow. Yes, many people have purchased SoundOff to drown out their partner’s snoring and are now getting the best sleep of their life!

Our Proprietary Pink Noise

SoundOff has developed a proprietary and specially designed Pink Noise. It is a modified, or shaped, Pink Noise, developed by a PhD in psychoacoustics. How did he do it?


Because SoundOff was invented to mask snoring, he went into his sound studio, found a bunch of snoring sounds on YouTube and played them at the same time. While all this snoring was playing he went to work to modify the Pink Noise to mask the snoring more effectively.


Some of the higher tones were decreased and some of the lower tones were increased. This shaped sound masks snoring and other sleep disrupting noises very effectively.

Our Pink Noise with the Comply foam tips make the SoundOff Noise Masking device superior to any other noise masking technology/devices currently available.


With SoundOff you can finally get the comfortable nights’ sleep you need and deserve.

Here’s how listening to Pink Noise helps you fall asleep and stay asleep:

  • Pink Noise has a calming effect on the brain. This helps a person relax and unwind so they can fall asleep.
  • Pink Noise helps mask disruptive background sounds which reduces the likelihood of waking up during the night.
  • Pink Noise aids in stabilizing sleep patterns -- helping one fall asleep and stay asleep -- for more continuous and restorative slumber.
  • The balanced spectrum of Pink Noise has additionally been reported to promote longer periods of slow-wave or deep sleep. This is crucial for consolidation of memory as well as overall cognitive function.


  • In short, the tentle, consistent tones of Pink Noise mask out disruptive environmental sounds. So, you don’t hear your snoring partner, banging hotel doors, barking dogs, or other annoying sounds. With Pink Noise it’s easy to fall asleep faster and stay asleep longer.

Studies on Pink Noise

A number of academic studies conducted on nocturnal sleep stability zero in on the effects of Pink Noise and how it interacts with the brain to promote sleep.

A study published in the Journal of theoretical biology found that steady Pink Noise reduces brain waves which increases stable sleep.


Studies by Northwestern University and Frontiers in Human Neuroscience, both found that exposure to Pink Noise during sleep led to an increase in deep sleep which is associated with physical restoration and memory consolidation.


Results from another study published by the (NIH) National Library of Medicine (Pink noise: effect on complexity synchronization of brain activity and sleep consolidation) yielded a synopsis based on 40 subjects; each observed over two consecutive periods -- one with pink noise exposure, and on without.

The Science Behind Pink Noise for Sleep

The NIH study then concluded that steady pink noise does, in fact, have a significant effect on reducing brain wave complexity which results in more stable sleep time--and by doing so, thereby improves sleep quality.


Subsequent studeis also showed an improvement in sleep quality with Pink Noise.


Researchers reported participants found it easier to fall asleep, slept deeper, and reported feeling more rested upon waking.

In her blog post “Pink Noise for Better Sleep, Memory, and More,” Harvard & Yale trained psychiatrist, Suruchi Chandra, MD, delves deeper into the science behind the extensive benefits of pink noise for sleep, cognition, and overall well-being.


Here, Doctor Chandra explains why emerging research on Pink Noise is more promising than White Noise when it comes to brain health:


  1. It can sound more soothing and be more calming for thenervous system.
  2. Our brain cells communicate through brain waves that follow a pattern similar to Pink Noise. And because pink noise can match our brain wave patterns, it may be more stabilizing for the brain.

3. As our brains age, they produce more white noise and less pink noise. In other words, pink noise may be associated with younger andhealthier brains.


She further states...


  • During sleep, our brains produce slower brain waves that allow the body and brain to enter a state of rest and restoration. There are fewer of the faster brain waves that occur during periods of focus and concentration...

They began with the hypothesis that steady pink noise can change the complexity of brain activities and could have a significant effect on improving sleep stability.
