Free Download 1 Hour of Pink Noise in MP3 as a Concentration, Memory, or Sleep Aid
You’ve likely heard of “white noise,” which is produced when the sounds of different frequencies are combined. Pink noise, on the other hand, is a type of sound in which every octave carries the same power.
A slightly more technical definition from Wikipedia:
Pink noise or 1⁄f noise is a signal or process with a frequency spectrum such that the power spectral density (energy or power per Hz) is inversely proportional to the frequency of the signal. In pink noise, each octave (halving/doubling in frequency) carries an equal amount of noise power.According to studies, pink noise, which includes sounds at lower, more consistent frequencies than white noise, seems to help people sleep better. Additionally, it's associated with memory improvement, which may be beneficial especially for those suffering from Alzheimer's disease or other conditions that affect the brain.
