Our world is made up of several kinds of noise, and brown noise, also called red noise, is characterized by its frequency and sound level.
What is Brown Noise?
What does brown noise do? To understand its benefits, it’s important to recognize the differences among various types of noise.
Brown noise is a deep, low-frequency sound similar to heavy rainfall or distant thunder. It differs from white noise, which contains all frequencies at the same intensity.
When comparing brown noise vs. white noise, the difference is straightforward: brown noise operates at lower frequencies.
What Does Brown Noise Do to Your Brain?
Brown noise affects your arousal modulation and auditory masking. It changes the way the brain processes internal thoughts and external stimuli.
What does brown noise do to the startle response? We naturally tune into abrupt changes in our environment. A sudden loud noise elicits a “startle response,” which immediately captures our attention.
Brown noise reduces this response by filling the space with a denser layer of sound that masks the sharpness of noises. This keeps the brain in a steady state instead of being constantly overstimulated by ambient sound.
You can see how brown noise for sleep would be so effective because it softens outside noise that can be distracting.
Brown noise effectively masks the high frequencies of white noise so the brain interprets the sound as less threatening, lowering cortisol levels and allowing the prefrontal cortex to remain focused on the task at hand.
Brown Noise Benefits
Brown noise benefits the brain by promoting sleep quality. Its tone is deep and warm, promoting increased focus, deep sleep, and sound masking by reducing the startle response to calm our thoughts.
It also mimics the sounds of the natural world, increasing relaxation, reducing sensory overload, and masking tinnitus. It is a great way to help our bodies prepare for the parasympathetic, rest stage of sleep.
Brown Noise for Sleep
Using brown noise effectively masks external sounds, reduces sudden distractions, and helps promote the right state for sleep. It is very effective at calming the brain and maintaining focus on relaxation.
Brown Noise for Anxiety and Stress
Using brown noise to relieve stress and anxiety is a powerful tool because the deep frequencies are physically soothing. The main benefits:
Parasympathetic activation
The lower frequencies of brown noise make us feel safe and grounded. They stimulate the vagus nerve, which tells our body to slow our heart rate and breathing.
Eliminates hypervigilance in the brain
Anxious brains often rely on the amygdala, our fear center, to constantly scan the environment for threats. Brown noise creates a sound blanket that helps alleviate this response, reducing stress and anxiety.
Repetitive thoughts
Getting stuck in anxious thoughts keeps us awake and restless. Brown noise gives the brain just enough stimulation to maintain mental activity without triggering racing thoughts.
Psychological sense of security
Brown noise provides the same feeling as being in the womb, with a muffled sound that taps into our primal sense of safety, which can be very comforting, especially during a stressful event or panic attack.
Brown Noise vs. White Noise vs. Pink Noise
Is brown noise good for sleep vs pink or white noise? Yes, but it is important to understand how all three work. The difference is about frequency and volume.
White noise is at the top of the sound chart, characterized by a sharp, hissy sound. White noise is like a wall of sound that is most effective at blocking all frequencies. Things like noisy neighbors, sirens, barking dogs, or other loud noises.
White noise is also an effective noise-blocking option for infants because it helps them fall asleep by mimicking the sounds of the womb.
Brown noise drops off much faster at higher frequencies, sharply reducing the high-pitched hissing sounds and leaving only the deep, soothing bass.
Brown noise aids sleep by masking high-pitched and loud sounds. It also helps individuals with ADHD to calm an unsettled mind.
Pink noise, on the other hand, is great for improving memory consolidation. It is also a good alternative if white noise is too jarring, because pink noise balances high and low frequencies in a way that sounds natural to the human ear.
How to Use Brown Noise
Maximizing the benefits of brown noise for sleep, focus, and anxiety depends on how you handle your particular environment. To maximize its benefits, use these tips:
-
Use high-quality speakers or headphones to accurately reproduce the deep rumble of brown noise. The speakers on phones and laptops don’t do justice to its deep tones. Over-ear headphones work well in this situation.
-
Your goal should be masking, not loud, drowning-out sound. Adjust the volume until you can no longer clearly hear the sounds you are trying to eliminate. 60-70 decibels should be your max.
-
If you aren’t using headphones, position the sound source between you and the source of the noise. Allow low frequencies to bounce off walls, creating a calming effect on the nervous system rather than being directed straight at your head.
-
Brown noise is also excellent for shifting from a busy day to the calm of our nighttime routines. Using brown noise for 20 minutes before sleep prepares the brain for rest and focus.
-
You can also use brown noise for meditation and to help the ADHD brain concentrate during high-friction tasks, such as writing and data entry.
