Noise as a Tool for Sleep Improvement

Last week I went to visit#LosAngelesTimes #LATimes for#SecretsOfSleep panel and got into conversation with #DrMichaelBreus. He mention noise as an #aid for a sleep, so which one exactly?

He saying Pink noise, I'm saying each of them and the White noise as the dominant, someone around saying Brown noise... We all studied it and researched it but still have different opinions, why is that? Please share your experience in the comments.

For those of you who is not following...#WhiteNoise is comprised of random and equal amounts of frequencies from the entire sound spectrum. This is why it is so effective at masking just about every external sound.
#Audiology research has discovered that the human ear can only process a given number of sound frequencies at once. White noise machines create a sound pattern utilizing all available #frequencies. This causes other noises to fade into the background and become less noticeable, preventing them from disturbing your sleep.

Common benefits of white noise include: Sound masking and cancellation, Improved concentration, Sleep promotion
#PinkNoise Some listeners find white noise to be harsh or tinny. One popular alternative is pink noise, which also includes noise from the entire spectrum but emphasizes specific, lower frequencies to create a deeper, gentler sound.

Some users compare pink noise to rushing water, heavy #rain or strong wind through leaves. This subdued, fuller sound offers many of the same benefits as white noise, such as eliminating background sounds, but it's more #relaxing for many listeners.

Common benefits of pink noise include: Improved focus, Alleviated headaches, Soothed babies and young children, Better sleep

#BrownNoise aka #RedNoise, takes thee low-frequency emphasis of pink noise even further to create a noise pattern that is closer to a buzz than a hiss. Often compared to rushing water, a low roar or deep hum, like that of a clothes dryer or train passing. The deeper qualities of the noise are great for relaxing and falling asleep.
Common #benefits of brown noise include: Relaxation or meditation, Improved #focus, Increased reading comprehension, Like the others, #sleep #improvement. #dfad
