Do you also get woken by car horns in the wee hours? Data from the World Health Organization shows that 25% of urban residents are bothered by ambient noise. But there's a special kind of noise that's becoming a sleep savior: white noise.
What is white noise?
Just as white light is a mixture of all colors, white noise encompasses all audible frequencies (20 to 20,000 Hz), forming a uniform, stable sound wave. Common everyday sounds like the hum of fans, air conditioners, and even the sound of television noise are all examples of natural white noise.
How to choose the 3 most popular "color" noises?
• White noise : Like the sound of an untuned radio, suitable for blocking high-frequency noise (such as speech)
• Pink noise : Similar to drizzle or ocean waves, with more prominent low frequencies. 80% of users report that it helps with sleep.
• Brown noise : Like distant thunder, with deep vibration, suitable for those with severe insomnia
3 major benefits of scientific evidence
Fall asleep 38% faster : New York University research shows that white noise can shorten the time it takes to fall asleep, especially suitable for street-level residents
Improved focus : Office background noise can reduce distractions among people with ADHD and increase learning efficiency by 22%.
Newborn soothing : 80% of babies fall asleep within 5 minutes in a white noise environment (simulating the womb environment)
⚠️ Safe Use Guidelines
• Volume ≤ 50 decibels (about the sound of an air conditioner running at low speed)
• Keep the bed at least 30cm away and avoid playing all night
• Recommended APP: Tide/Noisli (including natural scene mixing function)
Try it tonight: Use rain noise and set it to 1 hour to block out distractions and help you fall into deep sleep! What's your favorite sleep-inducing sound? Share it in the comments section.
