For years, White Noise has been all the rage when it comes to sound machines and sleep aids. But as more research continues to come out, the tides are quickly changing.
White Noise functions by blocking out outside sound because it encompasses all of the frequencies a person can possibly hear (about 20 Hertz to 20,000 Hertz). The consistency of White Noise creates ‘masking' effect, which sometimes helps people fall asleep faster by drowning out outside noise distractions.
Pink Noise, on the other hand, is a balanced mix of high and low frequencies, like the sound of falling rain or gentle ocean waves, making it soft and calming. It is much more balanced and soothing than White Noise. It also has more power in the lower frequency bands than White Noise does, and those strong bass tones make it sound less harsh to the human ear.
So Why Pink Noise for Sleep?
Pink Noise has recently become the darling of all sleep sounds, due to the fact that the research has shown Pink Noise increases time spent in deep sleep while improving memory. A study published in Frontiers in Human Neuroscience suggests that one easy way to get deeper, more quality sleep is to listen to Pink Noise.
What is special about the Pink Noise in Baby Dream Machine?
The Pink Noise in Baby Dream Machine has been sound-engineered and tuned to the right frequency bands to help children sleep. Not all Pink Noise is made equal and we worked with professional sound engineers to develop the highest-quality Pink Noise, while making sure it operates at safe volume levels for little ears.
