Many people are facing noise in the plan office or private room. But they don’t know there is a possible way to stay free from noise in the office or private room where you stay.
According to science, of course, it is possible to soundproof a room by following some steps. Now, you should know which colored noise is best for sleeping, studying, and concentration.
Here I am discussing different types of noise that you should know for proper sleep in your room. Among different types of color noises (colors of sounds), some are white, pink, brown noise, etc. They also have some differences according to scientific theory.
You are very excited to know that these types of frequencies (noise cancellation sound) can help you to hide other bad noise pollution. If you are interested in quality sleep and study, then you should continue reading…
You can increase hours of sleep with the help of noise-canceling white noise. This is the reason why it is important to know the types of frequency for your better life.
You don’t know which sound wave is useful in which condition if you will not use them properly. You are struggling with earplugs and someone will disturb you or make fun with the loud sound of music.
Then this time you are searching on how to survive from this unwanted sound without earplugs or ear headphones.
Sometimes you also find ways on how to sleep and block noise without using any kind of earplugs, when there is a dense population in the surrounding area. Many people face this type of problem like you.
After learning these topics, I get a better result by using useful noise. If you also want to get better results, then know the ways more and more.
These useful noise-canceling sound waves are used in our society. When I study, then I learn about topics like white, brown, and pink noise.
So let’s start to know what the differences are among them and I want to tell you that they have audible frequencies.
What Colored Noise is Best for Studying, Sleeping, etc.
First, you should know the meaning of bad noise. According to Wikipedia, it is an unpleasant frequency to hear. It may be loud as a situation.
Some different sound levels are not harmful to us if you can use them properly. Besides, useful noise can help you to hide unpleasant noise and give you better comfort.
White noise helps to sleep for all types of people with babies. It also helps to study work and other activities where concentration is needed. Pink noise is used for concentration and study. Brown noise is used for relaxation. Sometimes it is used for sleep too.
So to know more details about colored noise, you should continue reading. So don’t skip it.
Sound waves transfer from one place to another by a medium.
This medium can be air, metal, and water. But any wave cannot transfer through a vacuum medium.
Here, you should also know that light waves can transfer through a vacuum medium. This is the difference between sound waves and light waves.
What is the Actual Difference Between Pink and White Noise
Now, I am telling you what the definition of these colored noises is (Pink Noise vs White Noise). After reading the definition, you can easily understand the actual noise that is used in our social life.
White Noise Machine
Basically, for the white colors of light, the name is given white noise. Do you know that there are different types of sound waves?
It is a mix of all sound waves (constant sound or noise) and also human hearing sound. You also know that many unpleasant frequencies have a bad impact on your brain and body.
This is the reason why many suffering people use this wave to mask harmful sounds in a specific way. There are such good noise-producing sleep machines available for people to keep silent in the office, coffee shop, and study room.
You can also use it for sleep aid with you and your baby in the room. This machine has many other activities too. The name of this machine is the white noise machine.
There is almost the same energy level (energy per frequency) in the frequency band of white noise (groups of all frequency bands are called octaves). It is calculated energy per octave.
This is the reason why this sound may help in sleep apnea, acute insomnia, maintenance insomnia, behavioral insomnia, and chronic insomnia of people who take sleep medicine.
You should know this frequency which has its specific sound waves. It masks other harmful waves and combines them and finally generates specific waves. This wave helps people in their lifestyle activities.
Specification of White Noise
You should know that our human ear can be able to hear between 20 to 20000 hertz (human hearing range). That means any sound that we cannot hear. Only the sound which we can hear has the range between 20 to 20000 hertz.
Here, the frequency range of the white noise is 20 to 20000 hertz too. So It includes all sounds that we can hear. Here is also an example that I will give you from scientific theory.
Do you know that the combination of all colors looks white? According to science, this is true. On the other hand, all sounds in the range 20 to 20000 hertz indicate white noise where there are all sound waves in a specific combination.
I think, now, you have understood that concept.
Examples of White Noise
If I give you an example of this frequency, then you will understand it easily. In the old model television, when there is showing a disconnected channel then it produces a kind of sound spectrum like hiss or environmental sounds.
Here are also other examples too. The sound of the ocean waves, fan, wind, rainfall, nature sound, etc are the best examples of this wave.
These examples are called white noise because they have all combinations of sound waves that you can hear.
Think about what nature sounds like? It’s like hiss sound because in nature sound there also have all combination sounds of waves in a specific mixture.
Pink Noise
There are other frequencies that you may hear from others. Yes, now I am telling you about pink noise. Do read the specification with concentration.
If you don’t read this, then you cannot understand the difference between white and pink noise. Pink noise also has the same frequency that is 20 to 20000 hertz.
Also, this sound is a brunch of white noise. But there is a difference between white and pink frequency.
There is no extra loud sound at high frequency in the pink noise. On the other hand, there is a high loud sound at high frequency in white sound.
Besides, deep noise is available at low frequency in pink noise. In this sound, they need to be balanced to get a deeper sound at minimum frequency.
This is why, in the sound lab, sound engineers decrease volume to get high frequency or deeper sound. In recent days, pink frequency is becoming popular day by day to mask low harm sound frequency.
So this frequency is used for business purposes. Normally, pink frequency is used in sound equipment. It also creates such a frequency that helps people to sleep more deeply.
This pink frequency corresponds to the heating curve of humans.
Is Pink Noise Helpful?
The research is continuing for how pink frequency works better. There is also research for how well It works for a deeper sleep for boosting memory. So there cannot be said that it helps us to live our social life better.
In the research, it is found that pink frequency may decrease brain activity and proceed more deep sleep. This is the reason why there needs to be more research on this frequency.
However, you can try the best pink noise machines or apps for sleep and other specific needs. Also, take medical advice from the doctor before using this pink frequency and other frequencies.
When Pink Noise does not Work
In a special condition, pink frequency does not work. Most of the case, this special condition is available to many people. This special condition is the habit of poor sleep.
Among us, some people maintain a routine time of sleep quantity (sleep schedule) with their stable sleep habits. So this frequency does not work for those who maintain sleep in a routine-wise hourly time.
Difference Between Noise and White noise
Now, can you tell me if noise and white noise are the same or not? They are different for some conditions. Here, I am now telling that diffidence so don’t worry. Normally, any sound that creates a human’s disturbance is called noise.
It creates such a frequency that our brain cannot tolerate it. On the other hand, white frequency creates such a sound that feels better. It creates a specific frequency and our brain can tolerate it easily. The volume of normal frequency can be high or low.
The volume of this wave may be high and low but not as normal frequency. It is like a natural sound that helps us to keep fresh.
Why White Noise is Useful
I have already said that this frequency includes all types of frequency and creates a specific level of sound. This sound masking wave masks all other unwanted harmful sounds of our surrounding pollution like the sound of air conditioners or generators.
So it can be used for many activities. When you use this white frequency in any situation, of course, there needs to be a sound level of white noise. Now you can ask me how I can manage it as my requirement. Well, the answer is easy.
When you collect the right machine, you can maintain the setting that is already given in that machine. They also have a switching system to control white frequency. Now I am telling you where you can apply this wave in our surroundings.
What Noise Helps to Sleep from Blocking Disturbing Sound
If you go to bed early and you are suddenly woken up by any unexpected sound at midnight, then what will be your feeling! Then you feel unhappy and upset.
If there is white frequency around your sleeping room, then it absorbs unexpected sounds and makes you feel better. It is helpful when you face the traffic sound in your car.
White frequency from a white noise machine can mask that traffic sound in that situation. Now you have a question about how does white frequency works in the human brain scientifically?
No problem, I will tell you how it works. You should know that our brain loves smooth stimulation.
If any unwanted frequency tries to reach your brain waves when you are sleeping, then this white frequency absorbs that unexpected frequency and converts the smooth frequency that you need to sleep deep.
Thus this wave will be able to satisfy your brain.
It will be better if you concentrate on the door soundproofing and window noise proofing.
White Noise is Best for Concentration
When you are bored by doing a lot of work, there is no concentration to complete that work in that situation. The white frequency can help you to concentrate back and feel better.
Then again you can get started with your work with concentration. On the other hand, if you cannot concentrate on doing any work for outside sounds like traffic noise, then white waves also can help you to stay in that noisy place.
By doing this, most people also find it an effective way. It is used in manufacturing areas or noisy areas for giving more concentration to workers.
But keep in mind that excessive hearing this frequency all day can have a bad impact on you or your family. My recommendation is, use this wave when it is required.
Then you can get the advantage of using this wave.
Researchers Have Found about White Noise
There are many studies about the facility of this frequency. In a case study, white noise helps patients in the care unit. (source)
For knowing more, you can learn more from the internet. From another case study, we can know the positive result for more sleep of the patient of heart surgery in using this frequency. (source)
So here you can understand that this wave is becoming more and more popular, especially in health units. The sound waves of this frequency are easily absorbed by any patient’s brain. Normally, any human brain feels better, when it hears a sound that is good for health.
Sleep Expert Comment
There is a positive sign that is, white noise is favorable in the sleep expert area. In the sleep expert section, positive reviews are found in using it.
There is said in the national sleep foundation that useful waves can help to mask other unwanted frequencies. When anyone gets to a light sleep stage, they can better help from this frequency.
On the website of Babysleeppro. Com, dr. Rebecca (sleep specialist) says that parents should use this wave for getting better results.
Some other Noises You Should Know
Brown Noise
There is also another type of frequency that is brown frequency. The name is given by the person’s name Robert Brown who was the first to discover brown motion in the 1800s. So that frequency is also known as Brownian noise.
The brown frequency is deeper than the white and pink frequency. As an example, I can tell you that this frequency is like the sound of a heavy fall of water (waterfall). To produce this frequency is not easy work.
Brown frequency is more complicated to produce than white and pink frequency. The power of this frequency increases when frequency decreases. This is the reason why you find a lot of energy at the stage of low frequency.
You don’t need to reach high frequency to get a high power of brown frequency. Sometimes it is referred to as red noise because, in low frequency, red noise is almost similar to brown sound waves.
In our ear, the brown sound wave is almost the same as the white sound wave. You should know that the brown frequency is created by integrating white frequency.
Benefits of Brown Noise
It is also useful for some specific people who need more facilities. So here, I want to say that the benefits can be achieved by using brown noise like white and pink noise.
For knowing more I am telling you the benefits those are given below.
- For setting up more relaxation, It is used in special conditions. When you are showering, it can be useful to keep more stress-free and good feeling in muscle tension.
- Some people are using this brown frequency in their work environment because they say that brown frequency is useful to improve focus on work activities. In the working environment, there are various types of frequency waves that make a disturbance to workers. Here, the brown frequency can bring a better result, if it is in the workstation.
- Brown frequency merges all other noises of background music (bad noises) and gives a good feeling sound to keep you in the room comfortable. If anyone is shouting around your area, the brown frequency can reduce that frequency and give you peace.
- This frequency helps people to sleep more. A sudden unwanted noise can disturb your sleep. Here these frequencies merge that bad frequency and give a uniform frequency in the environment.
So you can try a brown noise generator as your requirement.
Researcher’s Search
You don’t think that only white, brown, and pink noises are discovered in this world. No, it is not right. There are more noises that I am not telling you about during my busy time.
The other noises may be harmful or not in our daily life. This is the reason why audio engineers and acoustic engineers are studying other noise waves. They are trying to get any facility from other sound waves.
I expect, In the future, there may be more good waves that will have a good impact on our future life. While researching, some researchers got sick from researching bad frequency waves. For this reason, we should respect the researchers.
However, I think you can understand the different noises that I have mentioned above. In the future, robots may be needed to reduce work.
So there need to be more manufacturing factories to produce robots and other functional products. So good sound will be needed in that place.
So it will be better for you to know information about how to utilize good noises spontaneously. I hope you do it better.
Black Noise
It is one kind of sound frequency (absence of sound). Some people use this sound wave to relax while sleeping. It is effective in little noisy areas.
Blue Noise
The function of this sound wave is the opposite character of brown noise. Water spray can be an example of this sound. Azure noise is also another name for blue noise.
Gray Noise
This sound wave is almost like pink noise. But there is a small specific difference between them. The sound of gray noise may differ for every listener who wants to listen to this sound.
My Viewpoint on Colored Noise
From the overall reading of noise types, I think, you can understand what is the difference between brown, white, and pink sound waves. You have also learned that all sound waves are not bad for our life.
The sound wave that our brain accepts as positive, is called good noise. On the other hand, the sound wave that our brain accepts as negative is called bad noises.
But some white frequency waves are not harmful to human life. You should know the proper use of a good sound wave.
Among those sound waves, white sound waves are especially popular for practical use. Most industries increase productivity by using this wave. Besides, there are white noise generating tools in the industry.
It is also called a white noise machine. You can get it from any marketplace because this noise generator is now available. Just you need to collect a proper machine or apps according to your using condition.
Noise reduction sound doesn’t make the room fully silent but it helps to reduce loud noises (ambient music sounds). So you should use the right noise properly.
FAQ: Colored Noise
What Noise Helps Baby to Relax Sleep?
For a healthy life, a baby needs actual sleep for daily life. Sometimes a baby doesn’t want to sleep at night. Besides, when a baby sleeps, a baby wakes up suddenly by hearing any bad frequency.
This is the reason why your baby may suffer from hearing disorders. Normally, sudden noise makes your baby suddenly wake up. So you need to reduce that bad frequency level from the environment of your baby room.
To avoid this situation and make your baby instantly sleep, the white frequency can help to absorb unwanted frequency and create a smooth white frequency for your baby.
What Type of Specific White Noise is Better for Studying?
You can select a specific white sound as your choice. Normally soothing and pouring rain noise is used most of the time. But you should select which type of sound is better for you.
