What is Pink Noise?
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 lower frequencies, which creates a deeper sound. Nature is full of pink noise, including rustling leaves, steady rain, and wind to name a few. To the human ear, pink noise sounds even and because it has the same tones in nature that we find relaxing, many people find pink noise very relaxing as well.
The SoundOff Sleep Sound:
SoundOff has developed a proprietary and specially designed sound, The SoundOff Sleep Sound.
The SoundOff sound is a modified, or shaped, pink noise.
It was developed by a renowned PhD in psychoacoustics. Some of the higher tones were decreased and some of the lower tones were increased. This shaped sound masks snoring and other noises at lower volumes.
The SoundOff Sleep sound 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.
Studies on Pink Noise:
A number of academic studies on nocturnal sleep stability zero in on Pink Noise and how it interacts with the brain. Results from one study published by the 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 one without.
They began with the hypothesis that steady pink noise is able to change the complexity of brain activities and could have a significant effect on improving sleep stability.
This study concluded that steady pink noise does in fact have a significant effect on reducing brain wave complexity which induces more stable sleep time—and thereby improves sleep quality.
In her recent blog post “Pink Noise for Better Sleep, Memory, And More,” Harvard & Yale trained psychiatrist, Suruchi Chandra, MD, explains why emerging research on Pink Noise is more promising than White Noise when it comes to brain health:
- It can sound more soothing and be more calming for the nervous system.
- Our brain cells communicate through brain waves that follow a pattern similar to Pink Noise. Because pink noise can match our brain wave patterns, it may be more stabilizing for the brain.
- As our brains age, they produce more white noise and less pink noise. In other words, pink noise may be associated with younger and healthier 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…
Pink noise appears to amplify the power of the slower brain waves during deep sleep. When administered at night, it may help people fall asleep faster and get deeper, less fragmented sleep.” Learn more about Pink Noise and the Brain by visiting Dr. Chandra’s blog (see link below.)
Studies on Pink Noise continue, and show additional promise in its’ ability to promote both relaxation and better focus as well as improved sleep. Meanwhile, we’re seeing a surge in actual therapeutic application across a broad spectrum of medical professionals for all these conditions. We’re also hearing from more SoundOff users who report they find extended benefits to their earbud usage—which includes providing better focus in noisy work and study environments.
A number of psychologists and Neuro-Field specialists, currently use Pink Noise to treat sleep disorders like Insomnia as well as brain-based conditions such as anxiety, depression and brain fog.
Typically, sleep disorders are characterized by slow brainwave deficiency (delta/theta waves) which help you to get to sleep, and stay asleep.
Many Sleep Specialists, such as those at the worldwide Neurofield Treatment Center Network, are finding success by addressing sleep and brain-based conditions with fewer medications and more of the sound and brain stimulation therapies–including pink noise.
The choice to use Pink Noise in our SoundOff earbuds has been rewarded with tremendously positive feedback. Customers frequently mention our Pink Noise specifically when telling us about their SoundOff experience. One in particular, calls it “Lullabye-esque.”
