A white noise system is a mix of sounds of different frequencies. Because of the range of frequencies, the noise is able to mask different types of noise. White noise has flat spectral density, and it has the same intensity throughout the frequency range.
White noise is derived from white light which is also a combination of different wavelengths of light. There are other types of noises such as blue noise, pink noise, brown noise and more.
A white noise system is quite harsh because its sounds high-pitched to the human ear. White noise alters background noise; there are no features in the sound quality so that it passes through the mind without alerting it, that is why we find it relaxing and soothing.
White noise is quite harsh to human hearing, so many white noise recordings or white noise system use other types of sound which work just as well as white noise to mask background sounds.
The most common one that we hear is pink noise; pink noise is essentially filtered white noise, it is filtered in a way that reduces the harshness and intensity and increases the frequency. It sounds more than pleasant than white noise and often mimics nature sounds like the rush of waterfalls, wind rustling through trees, the roar of waves.
White noise can also take other forms such as the hum of an air conditioner, the whir of a fan, crowd noise, or crackling fire.
If you suffer from lack of sleep and you are told to use a white noise system to lull you to sleep, it may seem unreasonable as noise usually keeps people awake and alert.
However, the way white noise works is that it blends annoying background sounds like a car honking outside your window, a dog barking, or music blaring into a seamless noise that does not register solidly in your mind.
White noise masks these sounds with the frequencies of its signal instead of drowning them out it reduce the effect of tinnitus, an annoying buzzing in the ear and it masks other distracting sounds.
A white noise system can even help babies fall asleep; It is well known that babies have a hard time falling asleep as their body clocks are yet to be regulated.
They respond quickly to sudden movements, and it makes them jumpy.
There are ways to calm them down, but if the ways you know don’t work, you can try a white noise system, it lulls them to sleep and produces a calming effect which helps them to stay asleep. A white noise system specially designed for babies are available for sale.
Adults have as much need for white noise machines as babies, maybe even more. A lot of people have problems falling asleep, and some have insomnia. Some people are unable to sleep in a room that is entirely silent; their minds are alert to every little sound that they hear. A white noise system blends these noises and makes a pleasant noise that is soothing and helps you sleep.
It is not the machine that makes you fall asleep; it is the soothing and peaceful environment it creates that helps you to sleep.
