Generate natural-sounding pink noise for better sleep, relaxation, and professional audio work. Pink noise's balanced frequency spectrum makes it more pleasant than white noise for extended listening.
What is Pink Noise?
Pink noise, also known as 1/f noise or flicker noise, has equal energy per octave rather than per frequency. This means lower frequencies have more power, creating a deeper, more natural sound. Pink noise is named because its spectrum is shifted toward red (lower frequencies) compared to white noise.

Frequently Asked Questions
What is pink noise?
Pink noise (also called 1/f noise) has equal energy per octave, meaning lower frequencies have more power than higher ones. This creates a deeper, more natural sound often compared to rainfall or wind.
Why is pink noise better for sleep than white noise?
Many people find pink noise more soothing because its frequency balance resembles natural sounds like rain or waterfalls. The reduced high frequencies are less harsh on the ears.
Why is pink noise used in audio testing?
Pink noise is used for speaker calibration because it represents how we perceive sound across the frequency spectrum. Equal energy per octave matches human hearing perception.
What is the difference between pink and brown noise?
Brown noise has even more low-frequency energy than pink noise, creating a deeper rumbling sound similar to thunder or a strong wind.
