While white noise is the most well-known and studied sound for improving sleep quality, some people find the 'hiss' of white noise unpleasant or distracting. Green noise, a lesser-known alternative, is a more natural and soothing sound that may help people fall asleep faster. It is generally a mix of nature-inspired sounds, such as rain, wind, and streams, and is often used to enhance focus, promote relaxation, and improve sleep quality. Research suggests that green noise may be especially beneficial for people who have racing thoughts and anxiety at night. However, there is limited data on the effectiveness of green noise, and the best noise for sleep depends on individual preferences.

What You'll Learn
Green noise is more natural and soothing than white noise
Green noise is a relatively new concept and is not as popular as white, pink, and brown noise. However, it is increasing in popularity and is considered more natural and soothing than white noise.
Green noise is a particular variant of white noise that is generally around a frequency of 500 Hz. It is associated with the soothing sounds of nature, such as the wind, rain, waves, or a stream. It is a mix of different nature-inspired sounds, which can make for a soothing listening experience. The natural sounds of green noise can help activate the rest-digest response, allowing our brains to rest.
White noise, on the other hand, contains all sound frequencies across the spectrum in equal measure. It tends to sound more mechanical, like static or a fan. While it can be effective in improving sleep quality and is often recommended for insomnia, some people may find the 'hiss' of white noise unpleasant or distracting.
Green noise is perfect for relaxation and can be especially effective in promoting better sleep. It can help to mask annoying sounds and provide a gentle background hum to drown out distractions. Research has found that listening to nature sounds (green noise) improved overall sleep quality for patients in hospital settings, where environmental noise and other distractions commonly disrupt sleep.
While there is limited data on the impact of green noise, some evidence suggests that it may help with sleep onset and improve sleep quality. Green noise might be particularly beneficial for people who have racing thoughts and anxiety at night. It may also be a good alternative for those who dislike the sound of white noise.

Green noise is better for blocking out environmental sounds
Green noise is a relatively new concept and is not as popular as white, pink, and brown noise. However, it is increasing in popularity. Green noise is a particular variant of white noise, generally at or around a frequency of 500 Hz. It is associated with the more soothing sounds of nature, such as leaves rustling in a gentle breeze, distant streams babbling, and the soft ocean waves, waterfalls, and rivers. It reminds people of nature more than other frequencies.
Green noise is perfect for relaxation and can be a great companion throughout the day. It can provide a gentle background hum to drown out distractions and help you relax. It is an ambient sound with a frequency range nestled between the more commonly known white and pink noise. It is generally a mix of different nature-inspired sounds, which can make for a soothing listening experience.
Green noise is especially good at blocking out environmental sounds and other distractions, like harsh lighting, that commonly disrupt sleep. It can be very effective in promoting better sleep. For example, one study found that listening to nature sounds (aka green noise) helped to improve overall sleep quality for patients in hospital settings. Green noise might also be beneficial for people who have racing thoughts and anxiety at night. It helps activate the rest-digest response (opposite to the more widely known fight-or-flight response), allowing our brains to rest.
While white noise is the most studied sound for sleep, some find the ‘hiss’ unpleasant or distracting. For those who dislike the sound of white noise, green noise might be a better fit to help you fall asleep. The best noise for sleep depends on your preferences, but if you find yourself tossing and turning, try tuning into some green noise.

White noise may be better for those with insomnia or ADHD
White noise is often recommended for insomnia, especially in noisier areas with a higher risk of noise pollution during sleep. This type of pollution could be from loud cars on a highway, a snoring partner, or loud neighbours. White noise can improve sleep quality, suppress background noise, and increase relaxation. Research has found that adults may fall asleep faster when they listen to white noise at bedtime.
White noise may also improve cognitive symptoms in people with attention-deficit/hyperactivity disorder (ADHD). Studies have shown that white noise can be therapeutic for children with ADHD. Additionally, white noise can enhance productivity, making it easier to tune out other noises in the office and an excellent tool for workplaces and study spaces.
While white noise is the most studied sound for sleep, some people may find the '"hiss"' unpleasant or distracting. For those who dislike the sound of white noise, green noise might be a better alternative. Green noise is a relatively new concept and is not as popular as white, pink, and brown noise. It is a particular variant of white noise, generally at or around a frequency of 500 Hz. It is associated with the more soothing sounds of nature, such as the wind, rain, or waves.
The best noise for sleep depends on individual preferences, and it may take some trial and error to find the perfect sound.

Pink noise may improve memory and sleep quality
While white noise is the most studied sound for sleep, some people find the ''hiss' it produces unpleasant or distracting. Green noise, a lesser-known sound for sleep, is a more natural alternative that may be more soothing for some people. However, there is limited data on the impact of green noise on sleep.
Pink noise, on the other hand, has been linked to improved memory and sleep quality, particularly in older adults. A study found that participants exposed to pink noise during sleep enhanced their memory recall abilities compared to those who slept without any noise. These participants also reported a significant improvement in their sleep quality. This suggests that pink noise may support memory function and play a crucial role in fostering restorative sleep.
Like green noise, pink noise is a filtered version of white noise, with some of the higher frequencies reduced. As a result, pink noise tends to be a softer, less harsh sound at lower frequencies. It is also centred on creating a consistent experience, like the steady fall of rain.
While the best noise for sleep depends on individual preferences, pink noise may be a good option for those seeking to improve their memory and sleep quality.

Brown noise may help with concentration and sleep maintenance
While white noise is the most studied sound for improving sleep, some people find the ''hiss' of white noise unpleasant or distracting. Green noise, which is associated with the soothing sounds of nature, may be a better alternative for those who dislike white noise. However, there is limited data on the benefits of green noise for sleepers.
Brown noise is an ambient sound that boosts the intensity of lower-frequency sounds, resulting in a deeper rumble than pink or white noise, which some may find more pleasant and soothing. It is similar to the sound of rushing water or rainfall, and it may help to reduce racing thoughts and improve sleep quality. Brown noise may also help with concentration, especially for people with ADHD, as it can stimulate the brain and reduce auditory distractions.
Brown noise has been reported to have a calming effect on the brain, helping to reduce anxiety, stop overthinking, and improve sleep. It can also mask annoying sounds, promoting relaxation and enhancing focus. While there is limited research on the benefits of brown noise, anecdotal evidence suggests that it may improve sleep quality and help with concentration.
Some people use brown noise to fall asleep and report that it helps them stay asleep throughout the night, preventing them from waking up suddenly due to tiny noises. It is also said to help with tinnitus, and some businesses use it in their wellness programs.
Overall, while the effectiveness of green noise and brown noise may vary depending on individual preferences, brown noise may offer potential benefits for both concentration and sleep maintenance.
