To understand how white noise machine works, we must keep in mind that our brain can only interpret a certain number of sounds at the same time. That’s why, when it captures the enormous quantity of sounds coming from white noise, it interprets them as if they were something distant.
Since hearing is one of the senses that continues to function while we sleep, to alert us to any potential risks, the sounds that occur around us can affect the quality of our sleep or even wake us up.
In fact, a study conducted at the Metropolitan University of Manchester found that there is a link between nighttime noises and nightmares. Sleep problems have also been linked to the onset of neurodegenerative diseases such as Alzheimer’s, because the brain cannot rest sufficiently.
And if that’s not enough, poor sleep quality has also been linked to cardiovascular problems. A very interesting study conducted at the University of Pennsylvania revealed that, although after some time we get used to certain noises because they produce less changes in brain waves. They continue to influence the heart rate, generating states of excitement.
Of course, not all people respond to noise the same way. Harvard University researchers have discovered that brain rhythms are crucial in the ability to tolerate noise. In a general sense, noise is more likely to wake us up during the second phase of sleep, the light cycle not REM. Children and the elderly are more vulnerable to interruptions caused by noise.
White noise machines for sleeping help to avoid any sudden interruption of the sound coming from the environment and, consequently, reduce the frequent awakenings during the night.

How We Choose These White Noise Machine
In the opinion of the experts consulted, there are factors that a good device must have. But besides the theoretical criteria, we also tried these devices ourselves to see what they are really worth.
For the test, we went through the proposed features and judged how easy they were to use. We then used a sound level meter to measure the decibel range of each machine, from the quietest to the loudest. This was completed by measuring sound levels.
In our measurements, all machines remained below 100 decibels (dB) at their maximum setting. This is the maximum volume threshold for an eight-hour exposure without the risk of long-term hearing damage. We also wanted a machine that promotes precise volume control over a wide range of sound levels, especially at the bottom of the scale.

White noise machines have become fashionable. It is not strange, given that they guarantee a restful sleep, becoming a natural alternative to sleeping pills, even if their functions go far beyond and some types can also be used to practice relaxation or improve concentration. However, before buying a white noise machine it is important to know how to choose the best white noise machine:
Who are you shopping for?
- For the whole family. In this case, invest in a slightly more expensive but versatile and durable model.
- For the parents. You can find entry-level models.
- For babies or children only. There are entry-level and high-end options, but you will need to invest a little more to have many features and leads.
In what context will the machine be used?
If you want to get a white noise machine for home use, you will have access to more inexpensive options. For portable use, there are also, but better increase the budget to gain strength.
White noise machines are devices that appear harmless, but remember: everything that works with electricity must be carefully studied, especially for use near a baby!
If you are interested in a cheap white noise generator, you should know that prices depend on several factors, including the range of sounds it offers and the quality of the sounds produced.
A basic white noise machine can cost between 20 and 40 Dollars. In this price range, you will find features that can be annoying and repetitive.
A white noise machine with digitally produced or recorded sound usually costs between 20 and 50 Dollars.
You can also find white noise generators that produce natural sounds with the use of an internal fan, with an approximate cost of 30 to 50 Dollars.
Dimensions, Weight and Transportability
All of the machines we analyzed turned out to be light and space-saving. It is really difficult to come across a model that you cannot easily carry in a bag or suitcase.
However, they are not all suitable for walks with babies or trips by car with a car seat. Check if there is a clip-on plastic loop: this will allow you to install the device anywhere, including, for example, on a stroller.
Ease of Use
When choosing a white noise machine, try to make it easy to use. Some have buttons on the machine for every sound offered. Others have a digital screen where you can scroll through the different sounds available.
Some configurations may be easy to use for one person but difficult for another, so we advise you to acquire a white noise machine that suits you.
Masking in white noise machines
There are white noise machines designed to provide only background sound. Others mask ambient noise in the immediate vicinity. Decide on the one that best serves you.
Power & Sounds
You can choose between a white noise machine that connects to a power outlet, runs on batteries or has the option to operate in both ways.
Sounds depend on the model of white noise machine you choose, these devices can produce sounds such as rain, birdsong, rainforest, ocean waves, flowing river, among others. Some white noise machines have added extras like FM radio or alarm clock.
There are two very common additional functions equipping almost all of the machines:
- Automatic shutdown, which can usually be programmed after 30, 60 or 90 minutes.
- The memory of the last settings, which saves you from having to reprogram everything each time if you develop habits.
And there are two frequent but rarer functions:
- The night light, especially on baby products, sometimes with the possibility of choosing between several intensities.
- The dedicated USB port for charging a phone or tablet.
Note that the volume is almost always adjustable.
Solidity and guarantees
Most brands offer a warranty of around 1 year, some up to 18 months or even 2 years.
It is very common to be offered, on white noise machines, a reimbursement policy, the duration of which is often between 30 and 60 days.
Robustness is the rule, and unpleasant surprises are quite rare, although we encourage you to consult the opinions before purchase and to avoid prices that are too good to be true.
This is especially important for babies.
Indeed, at first, they may have a little trouble understanding what this machine is, which sometimes makes a big noise.
If it adopts a cute form, such as that of a funny animal, they will be more inclined to see the object as something reassuring and to immediately appreciate the sounds it produces.
Hope this guide will help baby and their parents sleep better, gain peace of mind and focus. We recommend that you chat with other dads and moms on the web: they will be able to advise you on the products that their toddlers particularly liked.
We do our best to offer you a comparison allowing you to choose the best possible white noise machine. If we have missed information or new models, please don’t hesitate to leave a comment below or send us a message.
