Every day, we hear many different sounds that can affect our thoughts and
feelings. Among these sounds, white, pink, and brown noises have long been seen
as powerful tools for sleep, relaxation, focus, and creativity. They have many
uses in different situations.

Researchers study color noises with different frequencies in fields like
neuroscience, psychology, and sound engineering. Here is a brief exploration of
what gives these sounds their properties or what is some of the most studied
applications.


HOW DID COLORED NOISES BECOME POPULAR & IMPORTANT?

White, pink, and brown noise history explores how sound affects human perception
and thinking. These sounds have existed in nature for a long time. We have only
just begun to study how they impact the brain.


WHITE NOISE

Harold Stephen Black, an American engineer and physicist, created white noise in
the early 20th century. He became known for his significant advancements in
electronic engineering.

Black revolutionized the way electrical signals were amplified and processed by
inventing the negative feedback amplifier in 1928. This new idea allowed for the
creation and study of white noise. White noise has equal energy at all audible
frequencies.

White noise has all frequencies the human ear can hear, playing at the same
intensity. This makes energy evenly distributed in white noise. White noise is a
steady sound that can block out other noises. It is helpful for sound masking,
aiding in sleep, and testing audio.


PINK NOISE

The field of acoustics and signal processing attributed the discovery and
application of pink noise. In the 1950s, scientists and researchers explored
ways to improve sound quality and reduce distortions in audio systems. They
found that pink noise, which has equal energy per octave, sounds more balanced
and natural compared to white noise.

Equal energy per octave indicates that the sound evenly distributes its energy
across different frequencies. Pink noise has lower frequencies with more power,
making them stand out and creating a deeper, balanced sound.

Many people describe pink noise as soothing and natural to the human ear. It
sounds like rain or rustling leaves in nature. In practice, people use it in
various applications, from audio testing to sound therapy.


BROWN NOISE

Brown noise, often referred to as Brownian noise and red noise, has its origins
in the field of physics or mathematics. Robert Brown, a Scottish botanist in the
1800s, created the term “Brownian motion.”

He noticed pollen particles moving randomly in a liquid. Scientists call this
random movement Brownian motion. The audio version of this is named “brown
noise.”

The frequency spectrum of brown noise follows a inverse square law, mean that
the power decreases with they square of the frequency. Moving higher in the
frequency spectrum results in a significant decrease in energy.

This makes the noise sound “reddish” and emphasizes lower frequencies. This
creates a deep, rumbling sound. Brown noise has a smooth quality due to its
focus on lower frequencies. People use it for relaxation and as a sleep aid.


MECHANISM OF ACTION

The concept of using “color” noises to alter brain activity has been around
since the late 1800s. This is when researchers first discovered binaural beats.

Researchers found that when the brain hears two different sound frequencies in
each ear, it makes a new frequency. This new frequency is equal to the
difference between the two original frequencies. In 1839, scientist Heinrich
Wilhelm Dove found binaural beats, where two sounds make a new sound.

Finding that binaural beats impact brainwaves and mental states led to more
research in neurology and psychology. As technology got better, scientists began
studying white, pink, and brown noises. Researchers found that these noises have
benefits for relaxation, sleep, cognitive function, and stress reduction.
Research with people has helped us understand how certain sounds affect our
brains and mental state.


TYPICAL APPLICATIONS OF WHITE, PINK, BROWN, AND OTHER “COLOR” NOISES

Experts in neuroscience, psychology, and sound engineering have studied various
types of “color” noises. These include white, pink, brown, and others. All these
different sound frequencies work by influencing brainwave activity and neural
oscillations, promoting specific mind states such relaxation, focus, and
improved cognitive performance. Here is a summary of the most commonly observed
applications:


SLEEP IMPROVEMENT WITH WHITE & PINK NOISE

Research shows that white noise can help improve sleep quality, especially in
noisy environments. White noise helps cover up sudden noises, creating a
peaceful environment for better sleep.

Research has shown that white noise can improve sleep by reducing nighttime
awakenings and aiding in falling asleep quicker. Researchers have found that
white noise benefits sleep quality. It can help individuals stay asleep longer
and fall asleep more easily.

Pink noise has also demonstrated positive effects on sleep. A study in the
Journal of Theoretical Biology discovered that pink noise can enhance sleep
quality and cognitive performance. Synchronize brain waves during sleep to
achieve this. The study showed that pink noise can help create more stable and
synchronized brainwave patterns while sleeping.

Pink Noise for Cognitive Performance

Researchers have associated pink noise with improved cognitive performance and
memory consolidation. A study at Northwestern University found that listening to
pink noise can improve memory during tasks. This type of noise was more
effective than other noises or silence.

The study showed that people were able to remember things better while listening
to pink noise.

Researchers observed that this background noise had a positive impact on memory
retention. Researchers found that pink noise, a calming sound, can improve
memory and learning by helping with information processing. It’s a useful tool
for studying.

Relaxation and Stress Reduction: Brown, pink and white noise

Researchers have found that brown noise, along with white and pink noise,
induces a state of relaxation and reduces stress levels. Brown noise can help
calm the nervous system, promoting relaxation and reducing tension with its deep
and soothing sound.

Pink noise and white noise can help relax the brain and reduce tension by
matching its natural rhythms. Scientists are still studying these sounds. Using
them in sound therapy and relaxation techniques is becoming more popular. This
is because of their potential to improve mental well-being.


WHITE NOISE FOR FOCUS AND CONCENTRATION

White noise can help improve focus and concentration, but its impact may differ
based on the task and noise level. A recent study in Nature found that listening
to white noise at 45 dB can have several benefits. These benefits include
improved attention, accuracy, performance speed, creativity, and reduced stress.

Similarly, researchers found that white noise at 65 dB enhanced working memory
but also increased stress levels. These findings show that the best amount of
white noise for improving thinking skills may vary depending on the task. This
could lead to using white noise in workplaces and schools to help people perform
better.


INDIVIDUAL VARIABILITY:

Scientific research shows that different “color” noises have benefits, but
people may react differently to them. It’s important to recognize individual
responses may vary. Researchers have observed that individual preferences and
sensitivities play a significant role in the efficacy of different color noises.
Some people may find white noise more conducive to relaxation or focus, while
others may respond better to pink and brown noise.

Personal preferences, how individuals use them, and individual
neurophysiological responses can vary the effectiveness of “color” noises.
Experimenting with various types of noise can help you determine what works best
for you. Pay close attention to how each type of noise affects you. This can
assist you in finding the most effective noise for your needs.


ENOPHONES HELP YOU GET THE MOST OUT OF COLOR NOISES

Enophones can enhance the effectiveness of “color” noises by reading and
analyzing brain activity in real-time. Enophones use sensors to monitor
brainwaves and determine how close someone is to their desired mental state.
They use the information to change the sound levels, making the experience more
personalized and accurate for the user.

Enophones can adjust the sound of pink noise to help someone relax more deeply.
This customization is based on their specific needs. For instance, if the
person’s brain indicates they are still somewhat alert while using pink noise to
relax. This adaptive approach creates a more effective and immersive listening
experience so you can maximize the benefits of white, pink and brown noises. Get
