The human ear perceives the result as a pleasant, even sound-comparable in tone to the relaxing sounds found in nature. Because it has equal power at each octave level, (whether halving or doubling in frequency,) pink noise carries an equal amount of noise energy. This means we hear the lower frequencies in pink noise louder and more clearly than the higher frequencies. Whereas white noise has equal power per hertz throughout all frequencies. The power per hertz, in pink noise, decreases as the frequency increases. How does it differ from White noise? Pink Tones Some say it is called Pink due to a pink appearance in the visible light of the power spectrum. In the case of “Pink” noise, it is the lower frequencies we hear more intensely. These “colored” noises contain a wide audible spectrum-but each hue has a greater intensity in a narrow band of frequencies. Why is it called “Pink?” Just as different light frequencies are assigned color names (blue, violet, white…) sonic hues are assigned color names based on their mixture of sound frequency. Simply stated, Pink Noise for Sleep offers a gentler auditory experience-which helps you relax and settle into a peaceful slumber. While similar to the more familiar White Noise, Pink Noise uses deeper tones which produce a more soothing sound. Pink noise is a steady, even sound that filters out distracting or obtrusive noises. It’s also being used to treat brain-based conditions such as anxiety and depression-which can ultimately contribute to poor sleep health. This explains why experts in psychology, and Neuro-Field specialists, are finding Pink Noise effective in treating sleep disorders like Insomnia. Thus, falling asleep faster, sleeping deeper longer-and waking up less often, are all benefits of using pink noise for sleep. Listening to pink noise appears to amplify the strength of these brain waves during deep sleep. These slower brain waves make it possible for our bodies, and brains, to achieve rejuvenating rest. Our brains produce slower brain waves during sleep. Let’s look at what that means, and how Pink Noise goes beyond helping us achieve better sleep, to ultimately promoting better brain health. Speaking of brains, the effectiveness of pink noise in improving our ability to sleep, has everything to do with how this sound interacts with the brain. This makes using pink noise for sleep a no-brainer! Is there any better way to fall asleep than to the sound of waves crashing on the nearby shore? Pink noise helps us relax and fall asleep because it emulates the soothing sounds we hear in nature-like the sound of ocean waves, rain falling, or leaves rustling in the wind. Pink Noise helps us relax because it reminds us of soothing pleasant sounds we love in nature.
