What Is A White Noise Machine?

A white noise machine is a machine that produces white noise. Okay let me elaborate a bit on it. Any machine that produces white noise can be Light specrumcalled a white noise machine. Before I can fully answer your question on what is a white noise machine, you need to understand what white noise is.

What is white noise?

There is no exact definition for it, but let me explain it in this way. I am going to use light in the following example. Lets say you take a white light such as that from the sun and let it pass through a prism, you will see a spectrum of different colours being projected through the other end. 

The same can be said for a rainbow. After it has rained and the sun shines its white light through the clouds you will notice a rainbow. The reason for this is that the white sun rays are refracted by the water drops which act as a prism to give the different colours you see on the rainbow. An explanation for this is that white light consists of all the different colours you see on the rainbow.

And NO, there is not a pot of gold at the end of the rainbow and you will not change into the opposite sex if you stand under one 🙂


What the heck does this have to do with white noise??

Well, noise have nothing to do with the colours you see, but the principle stays the same. If you sit in a room filled with people and one person talks you will hear him/her very clearly. It will still be the same if two or three people starts to talk at the same time. It will be less clear, but you can still make out most of the conversation.

Now lets say you hear ten people speak at the same time, you will not hear a thing. It will then sound like a buzz in your ear that you cannot make something off. Now this buzz is called white noise.

White noise sounds consists of different sounds that is being played all together so that you hear something, but you do not concentrate on it. The sounds can be that of rainfall, waterfall, wind, forest or any kind of mixed sounds.

What is the use of a white noise machine?

If you have a problem with a barking dog, snoring partner, noisy neighbor or anything of this sort, a white noise machine can be very helpful. It will not cancel 100% of the sound, but it will at least take away most of it. What it does is, it manipulate your brain in hearing just the white noise and takes your focus off the other noises that you don’t want to hear.

If you have any problems regarding sleep such as insomnia or study because of noises that are making it difficult to concentrate or to fall asleep, you might want to look into a white noise machine.

Some of you might say:” OK we now know that white noise can eliminate other noises, but what if the white noise keeps me awake or takes your concentration off my work”. It is a good question, but let me explain further:

Because white noise have so many different noises playing at the same time, it will act as a background noise. When you listen to it for a while, you will not even notice it anymore. It is like breathing. You know you do it only when you think about it and you don’t take notice of it every second of your life.

White noise machines was also used by the secret service to make it difficult for other people to hear a discussion in a room on something important that is private. Mostly people use it to improve their sleeping conditions for a good nights rest.

Where can I find a white noise machine?

When I wanted one I went to my local store and could not find anything on white noise machines so I used an online store named Amazon. If you are not interested in buying one you can use your fan which can give a similar effect or you can go to my Best White Noise Machine Reviews page where I go into more depth of the machines available with all the features and different price ranges.

I wish you the best of luck and if you have any desire to ask a question you can leave me a comment below 🙂 .

    Thanks allot Kevin. For some people the white noise does not work. Especially if they focus on it for too long. The solution to this is to take your concentration somewhere else.
