Nothing is better than waking up feeling revitalised and prepared to take on the day. Sadly, many folks suffer from insomnia or struggle getting a peaceful nights sleep. Well, what you have been missing is a white noise machine, fan or hair dryer!

A possible explanation for poor sleep is the difficulty in establishing the conditions for a good night’s sleep (i.e., a room that is cold, quiet, dark, and devoid of distractions).

At the very least, these electronic devices can help with this. The constant, soothing sound they emit drowns out all surrounding sounds, be they sirens, dogs barking, or your housemate’s television.

Find out how this simple piece of sleep technology works. Continue reading for more!

What is White Noise? 

Audible to the human ear, white noise is a mixture of noises across a wide range of frequencies. It often has the hissing or “SHHHH” sound of static on the radio or TV.

Fun fact: A doctor or therapist’s office is one place you might have encountered these devices. These settings aid in maintaining confidentiality during sessions.

According to researchers, the use of white noise has been shown to aid in both falling asleep and maintaining a restful slumber.

According to Yogasleep’s community manager, “white noise is more than just recordings of ocean waves and rain noises.” Defined sonically, is “a collection of noises that has the same strength throughout the hearing range, generating a homogeneous sound excellent for disguising loud interruptions.”

This masking technique helps drown out ambient noise so you can get some distraction-free shut-eye.

How Does It Work?

The purpose is to serve as a masking sound for other potentially distracting sounds. If you’re attempting to sleep, you hear a lot of commotion outside your window; white noise can mask that so that you can get some sleep.

These frequencies span the whole audible spectrum, in order to mask other sounds. This makes it more challenging for the brain to identify individual sounds outside, which helps filter out distractions and induce a meditative state.

Although this type of noise may help with sleeping, focusing, and relaxing, you can also use it to mask out other distracting sounds like tinnitus (ringing in the ears). These devices, including noise machines, fans, and even hair dryers, can create this calming ambience.

How Do These Devices Help With Sleep?

The devices can aid sleep by masking other sounds in the surroundings by delivering a constant, low-level background noise. People with difficulty sleeping in quiet settings or hypersensitive to noise may benefit greatly from this.

Using these machines to get to sleep is based on the premise that it can provide a more stable and regular acoustic environment, which can be comforting and relaxing. This may help the mind wind down and get some shut-eye.

It could aid in sleeping patterns because it creates a comforting, familiar environment while simultaneously obscuring external noises. If you’ve always relied on a fan or machine to help you drift off, your brain may learn to link that sound with going to sleep, which in turn may aid in activating the body’s relaxation response.

But that is not all it is is good for. These devices might provide a welcome familiarity and comfort for those who have problems sleeping in new places.

Can White Noise Help Babies Sleep?

Babies may find it easier to go off to sleep if a constant, low-level background noise is present to cover any other sounds. This can be especially helpful for infants who have trouble falling asleep in quiet settings because they are susceptible to noise.

However, it’s important to remember that no two babies are exactly alike, so what works for one may not work for another. White noise may be helpful in putting your baby to sleep, but before using it, you should check with your baby’s paediatrician to ensure it’s safe and appropriate. One should use it with care, and it’s crucial to adhere to any rules or directions offered by the manufacturer.

Different Types of White Noise

Two varieties of white noise exist, each with its own set of benefits for things like sleeping, relaxing, and focusing. The following are examples:

  • Natural: Waterfalls, ocean waves, and rain are all examples of natural white noise. It’s typically used to help people unwind and drift off to sleep because of its calming properties.
  • Electronic: White noise generators, fans, and even hair dryers all contribute to what is known as “electronic white noise.” Its frequency and strength can be changed to fit the user’s specific requirements.

It’s worth noting that different people will respond differently, so trying out a few different varieties may be worthwhile to see which one works best for you.

White noise machine

Machines that generate a constant, low-level background noise are known as white noise machines. They are widely available in portable devices, speakers, and applications and are frequently used for sleeping, relaxing, and focusing.

Lets take a look at some pros and cons.


  • It can act as a noise canceler, making the surrounding area more consistent and peaceful
  • It has the potential to induce calm and relaxation, improving the quality of sleep and time spent winding down.
  • It can make one feel at ease and comfortable
  • Modifiable in terms of frequency and strength to accommodate a wide range of users and situations
  • Apps and devices that can be taken with you wherever are portable.


  • Possibly not everyone’s cup of tea
  • There are people who find white noise to be distracting or annoying.
  • Intense or prolonged exposure to it may be harmful to hearing.
  • It’s possible that a white noise machine will cost more than a fan or a hair dryer.
  • It is crucial to remember to switch off white noise machines when they are no longer needed, as specific models may not include a timer or automated shut-off mechanism.

While these machines might be helpful for some people they aren’t the only option for producing a soothing atmosphere. When considering using a machine, it’s wise to learn about your alternatives and weigh the benefits against any downsides.

White noise fan

White noise fans are extremely similar to the aforementioned machines. When activated, these fans reliably emit a barely audible noise in the background.

The purpose of these fans is to produce a more stable and predictable sound environment that can be comforting and pleasant by masking other sounds surrounding the room. In addition to helping you fall asleep, the fan’s hum can lull you into a sense of comfort and familiarity, which is especially useful for travellers who have problems falling asleep in strange beds.

Fans that produce a white noise effect are a great alternative to electronic devices, and they can be especially helpful for those who find the sound of a fan relaxing. They don’t use power, are inexpensive, and can help you relax without using a particular machine.

Depending on your individual needs and tastes, you may create a soothing and peaceful atmosphere with either a white noise machine or a fan. 

White noise hair dryer

Lastly, white noise hair dryers use a motor to create the sound of rushing air. Usually, dials or buttons on the hair dryer let you alter the buzzing sound’s decibel level and overall volume. Depending on the model, a hair dryer may also include a timer or an automated shut-off feature.

These hair dryers may not be as good as machines or fans at masking other sounds, and some people may find the sound of a hair dryer distracting. But, they have a similar effect to the other two electronic devices.


A good night’s sleep may be at your fingertips if you invest in a white noise machine to drown out any distracting sounds from the outside world.

These aids can facilitate falling asleep and maintaining restful sleep, and they may also assist in retraining your brain to recognise the need for sleep.

Adding one of these devices to your bedroom is a quick and easy method to set the stage for a restful night’s sleep. Happy snoozing!
