Frequently asked questions
What is the difference between pink and white noise?
White noise gives the same energy to each frequency, so the high frequencies dominate to the ear. Pink noise gives the same energy to each octave, which sounds more balanced.
When should I use pink noise?
For long work sessions or to fall asleep, when white noise feels too harsh.
How loud should it be?
Just loud enough to cover the noise around you. Keep a moderate volume, especially with headphones or near a sleeping baby, and place the device at a distance.
