What is Brown Noise vs White noise vs Pink Noise: Best Key Differences (2021)

Many of us have trouble while sleeping or studying or working in noisy environments and have tried many options such as: Soundproof a room or using earplugs, but very few have tried noise. Do you know what is Brown Noise or White noise or pink noise is?

How can such a sound help you to cope with ambient noise and sleep without problems?

If not, this guide will provide you with complete information on the difference between brown noise vs pink noise vs white noise, which is effective in a noisy environment.

I had a big problem with this during my college days due to loud roommates and I didn't encourage the using earplugs. I'm looking for a way to how to sleep without earplugs.

During this research, I learned a lot about the types of noise, especially brown noise, white noise, and pink noise, and after using them the results were amazing.

If you're really having the same problem, you should learn all about noise types. I think you already know https://www.soundproofplan.com/does-soundproofing-really-works.hml.

What is Brown, White and Pink Noise?

Did you know that the reason you can't focus is not because of the noise itself, but because of a change in noise, the person sleeping next to you when you purr, or the dog barking on the nearby street, the best examples for that whether the noise changes?

Therefore, using a different sound can help you cover up all unwanted sounds and make one common noise all the time, which can help you sleep better or focus more on studying or working.

Before continuing, let me clear your mind about light waves and sound waves, as they both travel in the form of waves, but sound waves need a medium to pass through, and light waves can travel in a vacuum.

I also suggest that you pay attention to the octave. The main term in acoustics is band of frequencies where the highest frequency is twice as low frequency.

Noise is of different types, but most people use three types of noise, as described below.

What is white noise? With white Noise Examples

The White noise gets its name from white light because it is a combination or combination of all sound wave frequencies and hence many people use this to mask other sound waves.

You can think of white noise as a lot of things combining and creating their own frequencies. When you put them together, the end result is white noise.

The white noise frequency range between 20 and 20,000 hertz, which is everything the human ear can hear and white light, which is a combination of each wavelength of visible light.

This means that it is a combination of 20,000 different melodies that can be heard or understood by the human ear.

On older televisions or radios that don't broadcast television or radio, you may have heard the sound of pixels moving around the screen like hissing sound. It's a white noise.

While we're going to take some other examples like rain or ocean waves, or the sound of a wind or a fan, they are also very similar to white noise because you hear different combinations of noises.

In the case of white noise, you may have heard that higher frequencies sound louder than lower frequencies, which can be annoying or fun at times.

The scientific reason for higher octaves contains more frequencies than lower ones. So imagine how many frequencies they can maintain at 20,000 Hz, which causes more noise.

In case you didn't know, there are a lot of industries that are dealing with white noise generator because research shows productivity or work efficiency, or the focus increases with the use of white noise.

What is pink noise? With Pink Noise Examples

The Pink noise is part of white noise and also varies its frequency between 20 and 20,000 Hz. Here, however, the main difference lies in the distribution of power between frequencies.

However, if white noise has the same power across all frequencies, it causes louder noise at higher frequencies, but pink noise does not have the same power at all frequencies.

At higher frequencies, power is reduced to Hertz, which results in no additional volume at higher frequencies or high power at low frequencies and low power at high frequencies.

Technically, this power is offset by increasing the frequency by increasing successive octaves which may contain more frequencies and balancing the power with the lower frequency octaves.

Well, in recent days, pink noise has been widely used in business due to its improved performance in masking low frequency noise and increasing productivity.

Pink noise is mainly used for testing speakers and sound equipment to balance frequencies and adjust the brain waves that generally contribute to help for positive sleep.

What is the brown noise?

The Brown noise is deeper than pink and white noise and is a combination of white noise, pink noise and blue noise, and is somewhere near white noise.

It is actually named after the 19th century botanist Robert Brown and is also called as Brownian Noise because sound signal change from one to another at any given moment.

White noise power remains the same over an octave, and pink noise power decreases with increasing frequency, but brown noise differs slightly, or vice versa, with power decreasing significantly with increasing frequency.

This means that at lower frequencies it will have a higher power, which is somewhat similar to red noise due to lower frequencies.

To feel the brown noise, you can hear the sound of a waterfall. Playing brown noise is not easy because sound technicians have to use each sample to create the next one by adding randomness.

What is Blue, Violet and Gray : Noises?

Good. For the most part, we only hear or talk about brown noise, pink, and white noise, but there are a few others that also play an important role in masking ambient noise.

What is blue Noise?

Blue noise is the opposite of pink noise, where the power or signal energy increases with increasing noise frequency.

This means that you will feel stronger at the highest frequencies. In terms of the proportion of increased energy, each subsequent octave is 3 decibels.

As a result, each octave has as much energy as two octaves under it combined, with an example of blue noise becoming a sizzling jet of water.

Blue noise is like blue light in the higher frequency spectrum of light and is mainly used to minimize distortion when mixing audio to audio.

What is Violet Noise?

Violet noise is like blue noise whose performance increases with increasing noise frequency.

Compared to blue noise, its energy increases sequentially by octaves to 6 decibels, which means its lower end is slightly higher than blue noise.

What is Gray Noise?

Gray noise is comfortable to listen to and is calibrated in the same way so that noise remains the same as pink noise.

It is close to white noise, but specifically tuned to the human ear, so this is specifically used in studies examining how certain people who hear, react and differ from others.

The lower end of the frequency spectrum is stronger than the middle or upper end and allows the higher frequencies to maintain the same performance, which makes it more comfortable to hear with the human ear.

Granted, there isn't a direct example to explain the gray noise, but somewhere you can hear it like a distant thunderstorm.

Do you use all The colors of noise?

Well, we've studied almost all of the best noise types and how to use them, but do you really know how all of these noises work and what colors of noise work best when studying or working?

Imagine that you are sitting in a room and communicating with someone. Then you can easily hear the noise. When others join you later, you can easily tell who said what.

But what if you were in a group chat with more than 100 people when the conversation turned into a roar and when someone new joined you, you wouldn't feel the difference because our brains couldn't tell the difference.

Our brains are constantly feeling voice changes, even if they are small, but what if you could make a constant noise?

The same goes for using a white, pink, brown, Violet, Gray or other Noise generation machine(Amazon) as it makes a constant noise that matches the brain waves.

If anything changes to outside noise, it doesn't affect the noise your brain begins to feel while you sleep.

Here are the best examples of noise that you can use in your everyday life.

Help you to sleep in Noisy environment

White noise is a great choice while sleeping at night. Make sure louder noise have white noise as they can mask any noise that occurs while you sleep.

During a night's sleep, there are times when you wake up with a sudden loud noise of the external noise and watch over it while you sleep with a white noise.

If you are interested in purchasing such a white noise source, there are a few that are worth checking out for the Best White Noise Generation machines (Amazon.com).

Focus while Studying

This works especially for students living in noisy areas and unable to focus on studying and looking for what color noise is best for studying.

In most cases, it is advisable to use white noise as it better mask the noise that occurs during studying.

It also depends on the noise level you are studying and you can increase or decrease the white noise level depending on your environment.

When writing

If your job is to write consistently, it's a good idea to use pink noise, as research has shown that it reduces distraction when you pause while writing or speaking.

Hearing loss Checks

This is when you can use the gray noise because it has the ability to calibrate according to normal hearing and it is very easy to spot someone's hearing disability.

This way noise is used repeatedly and you can experience your own noise by adapting to your environment.

My Opinion on Brown Vs Pink Vs White Noise

Our human brain reacts to the noise, even hearing from any source at night when water droplets falling from the tap can disrupt your sleep because the noise level changes slightly.

When you have all these sources of noise, you can't take your mind off what it's doing.

It is observed that in many industrial spaces, productivity or creativity has increased due to the introduction of this noise generator machine.

On a small scale, you can use a temporary voice solution with a free mobile app. If not, you can take a look at the noise generator offered in the same manual.

I think you have a detailed description of what brown noise, white noise, pink noise, and a few other noise are and how they are used.
