If you're struggling to sleep due to noisy neighbours, a snoring partner, or loud traffic, white noise or brown noise might be able to help. Both types of noise can help to mask disruptive sounds, but which one is better for improving your sleep quality? White noise is commonly recommended for blocking out background noise, but brown noise is growing in popularity, too. Some people find pink noise—which sits somewhere in the middle of the two—to be the most soothing. Ultimately, the best type of noise for sleep depends on personal preference.
| Characteristics | Values |
|---|---|

White noise can help to drown out distracting, unpleasant background sounds
White noise can be effective in drowning out distracting, unpleasant sounds in the background of your environment and promote better sleep. It can help mask disruptive sounds, such as a neighbour's TV or banging noises, allowing you to fall asleep and stay asleep.
Some people find the sound of a running fan or air conditioning soothing, which is a form of white noise. Other forms of white noise include the sound of gentle rain or a soft breeze rustling through trees. White noise machines can also be used to create these sounds and help you fall asleep.
However, it's important to be mindful of the volume when listening to white noise. Constantly listening at high volumes can harm your hearing and disrupt your sleep. It's recommended to keep the volume at 50 decibels or lower and to use a timer so that the noise doesn't play all night.
If you find that white noise isn't helping you sleep, you can try experimenting with other types of noise, such as brown noise or pink noise, which may be more soothing for some individuals.

Brown noise is deeper and more natural-sounding, which may be easier on the ears
Brown noise is a popular option for those seeking a good night's rest. It is known for its deeper and more natural sound compared to white noise, which some may find easier on the ears. Brown noise emphasizes lower frequencies while minimizing higher frequencies, resulting in a rumbling sound akin to a roaring river, heavy rainfall, or distant rumbling thunder. This distinct quality makes it particularly effective in masking external noises, such as neighbour's banging or TV noise, that can disrupt your sleep.
The preference for brown noise over white noise is often a matter of personal taste. Some individuals find the lower and more balanced frequencies of brown noise soothing and gentler on their ears, especially if they are sensitive to sound. It is worth noting that brown noise has gained popularity on social media platforms like TikTok, where users have praised its benefits, including improved focus and sleep quality.
While the scientific community is yet to reach a definitive conclusion on the effectiveness of brown noise, anecdotal evidence suggests it holds promise. Some users have reported that brown noise helps them fall asleep faster and improves their overall sleep quality. Additionally, brown noise has been advocated for individuals with attention-deficit/hyperactivity disorder (ADHD), with claims that it aids in enhancing focus and attention.
When it comes to optimizing your sleep, it is essential to experiment with different sounds and volumes to determine what works best for you. You can explore various options, such as sound machines, noise generators, or smartphone apps, to find the right combination of sounds and volumes that promote a restful night's sleep. Ultimately, the key to unlocking deeper and more restful nights may lie in discovering the specific noise colours and settings that resonate with your senses.

Some people find pink noise more soothing than white noise
White noise is a popular sleep aid, often recommended for people with sleeping difficulties and sleep disorders like insomnia. It works by masking background noise and tuning it out, helping to drown out distracting, unpleasant sounds. However, some people find the grainy static sound of white noise grating.
Pink noise is a sonic hue, or colour noise, that’s deeper than white noise. It uses a consistent frequency, or pitch, to create a more even, flat sound, like a steady rain, wind rustling through trees, or waves on a beach. Its added depth and lower waves filter out higher sounds, so you hear more relaxing, lower-frequency sounds.
However, there isn't a lot of scientific research on pink noise, and it's important to note that good sleep habits, like following a schedule and limiting naps, are still important. If changing your sleep habits doesn’t work, it’s best to talk with your doctor to determine the best approach for getting quality sleep.

There is limited research on the effects of pink noise, but it may help with memory
There is a growing body of research that suggests that pink noise may be beneficial for sleep. Pink noise is a sound that contains a random assortment of all audible frequencies, with more power in the lower frequencies. It has a lower pitch than white noise and uses a consistent frequency to create a more even, flat sound, like a steady rain, wind rustling through trees, or waves on a beach.
Pink noise may help people fall asleep faster and obtain better deep sleep. It does not appear to cause any strong side effects when played at a reasonable volume. One study found that playing steady pink noise at 60 decibels helped participants fall asleep faster. Another study found that people who used it slept more deeply and felt more rested when they woke up.
There is limited research on the effects of pink noise on memory, but it may help with memory consolidation and creation. Deep sleep is critical for maintaining a robust memory, but both decline with age. In one study, researchers found that older adults who received pink noise sound therapy during sleep had improved sleep quality and performed better on memory tests the next day. Another study found that younger adults who listened to pink noise during an afternoon nap performed better on verbal memory tests.
While these preliminary studies are promising, they have typically involved a small number of participants, so the results are not yet conclusive. More research is needed to determine how pink noise affects sleep, focus, and memory. However, it is safe and has no known downsides, so individuals may want to try it to see if it helps with sleep and memory.

Brown noise is being touted as a treatment for improving focus and attention for people with ADHD
Brown noise is a low-frequency background sound that has gained popularity, especially among people with ADHD. It is said to help adults with ADHD improve their focus and productivity by stimulating their brains and drowning out distracting background sounds. Some people with ADHD have described their brain as a “noisy" head with chaotic thoughts competing for attention, and brown noise is believed to help harness the neurons and quiet these noisy thoughts.
While there is limited scientific evidence supporting the benefits of brown noise for ADHD, some studies have indicated that listening to white or pink noise may benefit people with difficulties concentrating. A 2021 study found that beta waves, or frequencies between 12.5 and 30 Hz, improved focus among people with ADHD. Another study from 2007 reported that white and pink noise benefited cognitive function in people with ADHD and attentional difficulties.
However, the 2007 study did not examine the differences between white and brown noise. Considering that white noise has a balance of all frequencies, while brown noise primarily uses lower frequencies, it is possible that brown noise may be equally or even more beneficial. This is because brown noise has a deeper, bass-like tone that may be more soothing and effective at masking distracting noises.
Some people with ADHD have anecdotally reported improvements in focus and a calming effect when using brown noise. One individual described it as feeling like their "brain is being hugged." While the exact mechanism behind these improvements is still up for debate, experts suggest that brown noise may work similarly to white noise in enhancing cognitive function and concentration in people with ADHD.
In conclusion, while more research is needed to definitively prove the benefits of brown noise for ADHD, it is being touted as a potential tool to improve focus and attention for people with this condition. It may be worth experimenting with brown noise, in conjunction with other treatments, to determine its effectiveness for individuals with ADHD.
