The Sound of Sleep: Noise Types to Help You Rest Better

White noise encompasses all audible frequencies played at equal intensity, producing a consistent "shh" sound similar to a humming fan or static television. This uniformity helps mask sudden environmental noises, such as traffic or a snoring partner, preventing disruptions during sleep. By providing a constant auditory backdrop, white noise can facilitate a smoother transition into sleep and reduce nighttime awakenings.

Pink noise is characterized by a balanced distribution of sound energy, with more emphasis on lower frequencies, resulting in a deeper, more soothing sound akin to gentle rainfall or rustling leaves. Studies suggest that pink noise can enhance deep sleep stages and improve memory retention by promoting stable brainwave activity. Integrating pink noise into your sleep environment may lead to more restorative rest and increased relaxation.

Brown noise, also known as red noise, further amplifies lower frequencies, creating a richer, deeper sound reminiscent of distant thunder or a powerful waterfall. This type of noise can be particularly beneficial for individuals with heightened sensitivity to sound, such as those with ADHD, as it provides a "blanket" of sound that aids concentration and relaxation. Incorporating brown noise into your nightly routine can help quiet a racing mind and facilitate a smoother onset of sleep.
