Pink Noise

Pink noise is a type of sound that contains equal energy across all octaves, meaning its power decreases by about 3 decibels per octave as frequency increases. Unlike white noise, which sounds like static and has equal intensity across all frequencies, pink noise emphasizes lower frequencies, creating a more balanced and natural sound resembling rainfall or rustling leaves. It’s often used in audio testing, music production, and relaxation settings because its balanced frequency distribution is soothing and helps improve sound quality or sleep.
