Forget white noise! BROWN NOISE is the latest trend to take over TikTok

If you’re struggling with sleep, you’ve probably tried listening to white noise to help you doze off.

White noise refers to sound that contains all frequencies equally, such as static from an untuned radio or TV.

While white noise has been used as a therapy for years, many TikTokers swear by another form of noise – brown noise.

Brown noise is a sound that contains all frequencies, but with higher energy at lower frequencies, such as a violent waterfall or thunder.

In recent weeks, videos have been posted on TikTok acclaiming the benefits of brown noise, with users claiming it can slow down your thoughts, help you focus and improve sleep.

MailOnline has delved into the science of brown noise, including what it is and why it has taken over TikTok.

One user posted a video and wrote: “Where did the thoughts go?!”

In recent weeks, a series of videos have been posted on TikTok acclaiming the benefits of brown noise, with users claiming it can slow down thoughts, help you focus and improve sleep.

Noise colors

There are three main “colors” of noise:

White noise

  • All frequencies audible to the human ear
  • The energy is evenly distributed over these frequencies.
  • Sounds include fan, TV noise, radiator hiss, air conditioner hum.

pink noise

  • All frequencies audible to the human ear
  • Energy is more intense at lower frequencies
  • Sounds include rain, wind, rustling leaves, heartbeat

brown noise

  • All frequencies audible to the human ear
  • Energy even higher at lower frequencies
  • Sounds include strong waterfalls, rumbling thunder, low roar

What is brown noise?

While you may not be familiar with the term “brown noise”, chances are you’ve heard it without even knowing it has a special name.

There are three main “colors” of noise – white, pink, and brown (also often referred to as red).

All three forms of noise are made up of all frequencies audible to the human ear, but the key difference is how the energy is distributed across those frequencies.

In white noise, the energy is evenly distributed, resulting in a consistent humming sound.

Examples of white noise include the hiss of a radiator, the hum of an air conditioner, or TV noise.

In pink noise, the energy is unevenly distributed across frequencies, and is instead more intense at lower frequencies.

This results in a slightly deeper sound such as wind, rain and heartbeat.

Finally, brown noise has even more energy at lower frequencies, resulting in deeper and stronger sounds such as strong waterfalls, low roars, and quiet thunder.

“Like pink noise, brown noise contains sounds from every octave of the audio spectrum, but the frequency power decreases with each octave,” the study says. Sleep Foundation explains on his website.

“This reduction is twice that of pink noise, causing people to perceive the sound as deeper than white or pink noise.”

Why did he take over TikTok?

A quick TikTok search for “brown noise” brings up thousands of videos from people who love the sound.

TikToker @natalyabubb posted a video of her first brown noise listening experience, writing “What. This is true? Where did the thoughts go?!

Another user, @fleet.wood.mak, said listening to brown noise was “the quietest thing my brain has ever had.”

Meanwhile user @bentelereski joked, “The girls weren’t kidding when they said brown noise was the key to success.

“I put on my headphones, turn on a brown noise Spotify playlist, and I’m immediately unstoppable.”

WHAT IS TINNITUS?

Tinnitus is the name given to auditory noises such as ringing, buzzing or hissing that are not caused by an external source. NHS.

This is due to damage to the cochlear hair cells in the inner ear, which expand and contract in response to sound vibrations.

Very loud sounds—in a nightclub or through headphones—can overload these cells, causing them to be temporarily or permanently damaged.

The damage causes other parts of the ear to overload to compensate for the loss of function, leading to tinnitus and eventually chronic hearing loss.

According to the charity Action On Hearing Loss, tinnitus affects one in ten British adults.

Treatment focuses on counseling and therapy to help people find ways to manage their condition and reduce any anxiety it causes.

Tinnitus Retraining Therapy uses sound therapy to retrain the brain to switch off and become less aware of ringing and buzzing.

Deep breathing, yoga, and participation in support groups can also help.

Does it really work?

While TikTokers claims that brown noise is a game-changer for sleep, its impact has yet to be widely studied.

However, previous research has shown that brown noise may be useful in some other conditions.

AT 2017Researchers at the University of Milan tested the effects of brown noise on people with tinnitus, a condition that causes ringing in the ears.

The researchers tested the effect of different colors of noise on 20 patients who suffered from tinnitus.

Their results indicated that the preferred sound was white noise, followed by brown (referred to as “red” in the study) noise.

“Two-thirds of the patients preferred white noise, making it the most attractive of the options,” the researchers wrote.

“The rest of the patients cited red (brown) noise as their preferred sound because it reminded them of soothing noises such as showers or rain. No one chose pink noise.”

Other 2020 A study has shown that listening to brown noise can improve work efficiency and memory.

In the study, researchers at Chung Shan Medical University Hospital recruited 22 participants who listened to red, pink, white, or no noise during a task.

The results showed that the participants showed better performance and memory when listening to red, pink and white noise than in quiet environments.

“Noise is now thought to adversely affect hearing and health,” the researchers wrote.

“However, experimental results show that certain noise can increase the comfort of the environment.”

While short bursts of brown noise are likely to do some damage, studies have shown that using noise as a permanent sleep aid can be risky.

Are there any risks?

While short bursts of brown noise are unlikely to cause any damage, studies have shown that continuous use of noise throughout the night can be risky.

In 2020researchers at the University of Pennsylvania analyzed 38 previous studies on the use of noise as a sleep aid.

Their analysis found that there was little evidence that continuous noise helped people fall asleep, while one study even showed that it led to more sleep disturbance.

Speaking with The keeperProfessor Matthias Basner, who led the study, said: “Whenever we are exposed to sounds and noise, the inner ear translates them into nerve signals, which are then interpreted by the brain.”

“This is an active process that produces metabolites, some of which are harmful to the inner ear.

“Perhaps you need a period when the auditory system can calm down, recover and prepare for the next period of wakefulness.”

What other ways can you improve sleep?

If you’re struggling to sleep, Royal College of Psychiatrists Here are some tips to help you fall asleep:

DO

  • Make sure your bed and bedroom are comfortable – not too hot, not too cold, not too noisy.
  • Make sure your mattress supports you properly. If it’s too tight, your hips and shoulders are under pressure. If it’s too soft, your body sags, which is bad for your back. As a general rule, you should change your mattress every 10 years to ensure the best support and comfort.
  • Get some exercise. Don’t overdo it, try swimming or walking regularly. The best time to exercise is during the day, especially in the late afternoon or early evening. This may disturb your sleep later.
  • Take some time to properly relax before bed. Some people find aromatherapy helpful.
  • If something is bothering you and you can’t do anything about it, try writing it down before bed and then tell yourself to do it tomorrow.
  • If you can’t sleep, get up and do something relaxing. Read, watch TV or listen to soothing music. After a while, you will feel tired enough to go back to sleep.

NOT

  • Do not stay without sleep for a long time. Go to bed when you feel tired and stick to the habit of waking up at the same time every day, whether you feel tired or not.
  • Caffeine stays in your body for many hours after you last drank tea or coffee. Nowadays, there are many carbonated drinks and even hard candies that contain a lot of caffeine. Stop drinking tea or coffee in the middle of the day. If you want a hot drink in the evening, try something dairy or herbal (but make sure it’s free of caffeine).
  • Don’t drink a lot of alcohol. This may help you fall asleep, but you will almost certainly wake up during the night.
  • Don’t eat or drink a lot at night. Try to eat dinner early in the evening, not late.
  • If you had a bad night, stay awake the next day – it will be harder for you to fall asleep the next night.
  • Don’t take diet pills – many of them will keep you awake.
  • Avoid street drugs like ecstasy, cocaine, and amphetamines—they are stimulants and, like caffeine, keep you awake.

CAN YOU LEARN WHILE THE TIME IS?

It’s the perfect quick learning tool to play a language tape or re-record at night while you sleep.

But those who desperately hope that the information will reach them while they are taking a nap may be disappointed.

Scientists have previously found that the brain actually perceives what it hears during REM sleep, the time we spend mostly sleeping, usually in the morning before we wake up.

Leaving the tape on at night is probably counterproductive, since information received in deep sleep can be completely lost.

French researchers have found that sound played during certain periods of deep sleep can make it harder to absorb information upon waking than if you had never heard it before.

It is believed that this happens because at this time the brain is busy erasing memories, and new knowledge is thrown away with them.

In a study published by experts from the PSL Research University in Paris in August 2017, researchers tested sleep learning by playing white noise to 20 participants, which contained sound patterns.

Sounds heard during REM sleep (rapid eye movement) were remembered by these people when they woke up.

It was easier for them to identify white noise that contained repetitive sounds because they heard it in their dreams.

But the noise played while people were in deep sleep, which is almost a third of our sleep, was forgotten.
