What is White Noise

Sleep better with a little noise… White Noise

Some people equate white noise to certain ambient sounds, such as a whirring fan or air conditioner, but they are technically not the same. The effect on your ears may be similar, but by definition, white noise must consist of all audible frequencies played randomly at the same amplitude.

What is Sound?

A sound is a form of energy made by vibrations; these movements are also called sound waves. Sound is made up of many different & varying frequencies.

As humans, we can generally hear a range of frequencies from 20 to 20,000 Hz.

What is White Noise?

White noise is what is created when all of the different frequencies of sound are mixed simultaneously.

Hence creating a background noise that masks other sounds.

How Does White Noise Work?

When there are unexpected noise changes, we’re often distracted by the sudden conflict of noise, especially if we are sleeping.

White noise effectively blocks out those changes making it easier to sleep through the night.

For this reason, a lot of people leave a fan, air conditioner, television, or air purifier switched on through the night, which essentially creates ambient noise to help muffle other sounds in the room to promote a night of peaceful sleep.

If you are trying to concentrate in a disturbing environment and there aren’t these filters in place, you could always listen to white noise.

Poor quality of sleep affects us in all areas of our life. Did you know that one in three people have difficulty sleeping?!

Is White Noise Machine the Answer to All of Your Sleep Problems?

Experts have discovered that broken sleep is, in fact, as detrimental to our body and our brain as having no sleep at all.

Lack of sleep affects us both physically and mentally. When we are tired, we experience mood changes; we become more stressed, we have a lower tolerance for things that we ordinarily would be able to deal with easily. We can become irritable and have a reduced level of concentration. We find ourselves having short attention spans, and we become less alert; this can lead to harm because our judgment becomes slow and impeded. Quite simply, without sleep, we do not function well at all.

What is Insomnia?

In a nutshell, it is a lack of or poor sleep. It is known that approximately one-third of us do not get as much sleep as we would like or need!

If you suffer from any of the following, quite simply, you are suffering from poor sleep:

  • Do you often wake up before you are supposed to?
  • Do you find it difficult to get to sleep?
  • Do you find yourself waking up during the night?
  • Do you sometimes not feel refreshed even after a night’s sleep?

While insomnia itself is a medical condition, many people are suffering from poor sleep simply because of the environment they’re living in. Wow! This means you can make a difference; you can make changes to help you achieve a good night’s sleep.

Did you know up to 70% of people are biologically hard-wired not to be able to sleep through distracting sounds at night?

If noise pollution such as barking dogs, garbage trucks, noisy neighbors, or your partner’s snoring keeps you awake at night, it may be time to consider investing in a white noise generator.

What Exactly is White Noise?

White noise is a specially crafted sound byte, which is used to drown out all background noises. It works by restoring a sound equilibrium,  which means that it will help reduce the amount of noise around you that grabs your attention, and steals your sleep! A calming background shhhhhhh masks noises that commonly prevent you from falling asleep or that cause you to wake up in the night. Sounds that commonly annoy us, including tinnitus, disappear from our hearing, resulting in a long, restful sleep.

What is a White Noise Machine?

True white noise can only be created electronically. Devices such as the Dohm Dual Speed have been specially engineered to create the exact frequency needed to normalize external sounds. While other similar sound masking devices are on the market, such as white noise apps, only machines designed to play the ‘shush’ sound on a no-loop, no recording playback will be truly effective for banishing unwanted disturbances.

What Affects Sleep?


Your bedroom should be a relaxing place for you to drift off to sleep. Noise is a big contributing factor when it comes to lack of sleep. Eliminate noise from your bedroom and improve your sleep.

Use earplugs to block out unwanted noise from outside sounds and or snoring partners.


The temperature of your room can create a favorable sleep environment. If your room is either too hot or too cold, it could impact your slumber. Use fresh breezes, a fan, or air conditioning to keep cool on those warmer nights, and make sure you have extra bedding or heating during the colder months.


Managing the light in your bedroom can help with a peaceful night’s sleep. When going to sleep, always ensure that your room is dark. Dim the lights and turn off electronic devices.

Hide your clock! One… it makes for a bright light to wake & disturbs your sleep through the night & two… at times when you wake before you are scheduled to, you may find yourself laying awake longer watching the time or thinking about how long you have until you wake. Digital clocks increase your arousal level; this is not productive for relaxation or sleep at all.

Make sure that you have blackout curtains or blinds. If your room is still not dark, wear a sleep mask!

We have a fantastic range of light, comfortable eye masks that block out light to aid in a great night’s sleep without early morning wake-ups!


Being comfortable is imperative for a peaceful night’s rest. Your bedding, including your mattress, pillow, and linen, should all be fresh, clean, and most of all comfortable. After all, you spend a third of your life in bed! It’s easily worth warranting that you have ticked all the right boxes when it comes to quality bedding!

Who can use a White Noise Machine?

White noise machines can be used by anybody looking to drown out background noise or even silence.

Every week we sell the Marpac White Noise Machines to parents with bubs and small children (I speak from first-hand experience with both of my children raised from a very young age with the Dohm in their rooms – and can not recommend them more highly. We didn’t ever have to worry about tiptoeing around the house. We enjoyed our evening dinner parties, and the boisterous, early waking wild birds were no longer an issue.)

Many tinnituses suffer wonder how they ever functioned without their sound machines. Partners or snorers call them “marriage counselors” 😉

Age is not specific, nor is gender. We receive notes of thanks from men and women, young and old, from shift workers to uni students and the elderly.

We have a large following of customers who love their Dohms for creating a “private” environment for patients and staff. Our sound machines are often used by Doctors, Solicitors, Psychologists, Managers, etc., to ensure conversations of a confidential nature are kept just that!

At the end of the day, the sound machine’s goal is easily achieved by helping to create a peaceful ambient noise allowing people to focus on what they’re doing.

A Natural Sleep Aid?

A 2008 Consumer Report study actually found that white noise machines were virtually as effective for problem sleepers as pharmaceutical sleep aids. This is definitely something, which has propelled them into the limelight in recent years. Therefore the white noise machines are frequently purchased by those wishing not to take anything medicinal or toxic to help them sleep.
