White noise is a popular sleep aid that has been shown to improve sleep quality and onset. However, some people find that white noise does not help them sleep better. If you are one of those people, you may want to try pink or brown noise. Pink noise has been shown to enhance deep sleep, improve cognitive performance, and decrease sleep onset. Brown noise is similar to pink noise but is deeper and grainier, resembling the sound of a distant thunderstorm or strong wind.

What You'll Learn
Pink noise
Initial studies have found that pink noise may help people fall asleep faster and obtain better deep sleep. One early study found that playing steady pink noise at 60 decibels—more or less the volume of a refrigerator—helped participants fall asleep faster. In a more recent study, researchers programmed a pink noise audio track to decrease in volume as people transitioned into sleep. Not only did this system help participants fall asleep faster, but it also helped them reach deep sleep earlier.
Another study found that participants' brain waves gradually slowed in synchrony with a pink noise soundtrack, helping to stabilize their sleep. Researchers have also succeeded at enhancing deep sleep by playing quiet bursts of pink noise at strategic times during the night. Deep sleep is the most restorative sleep stage.
There is also some evidence that pink noise may boost your memory. A recent study found that older adults who used it at night performed better on memory tests the next day.

Brown noise
If you're looking for an alternative to white noise to improve your sleep quality, brown noise might be the solution. Brown noise, also known as red noise, is a type of sound that contains frequencies from every octave of the sound spectrum. However, unlike white noise, the power behind the frequencies in brown noise decreases with each octave, resulting in a deeper and more bass-heavy sound. Some people describe brown noise as resembling the soothing sound of rainfall or a shower.
To incorporate brown noise into your bedtime routine, you can use a sound machine or play it through your phone or computer. There are numerous apps and websites that offer brown noise tracks or loops, allowing you to customize your sleep environment. You can also find relaxing YouTube videos that combine brown noise with calming visuals, providing both auditory and visual relaxation.
When setting up your brown noise, consider whether you prefer it to play continuously throughout the night or only as you fall asleep. Using a timer can be helpful to ensure the noise turns off at your desired time. It's also important to be mindful of the volume, as prolonged exposure to loud noises can potentially impact your hearing.
While brown noise has shown promising results for many people, it's important to remember that everyone's sleep needs are unique. If you find that white noise isn't improving your sleep, it's worth experimenting with brown noise or other alternatives like pink noise to find what works best for you. A good night's rest is essential for your overall health and well-being, so don't hesitate to explore different options to optimize your sleep quality.
