What is pink noise?
Pink noise has less energy in the high frequencies than white noise. The result is balanced to the ear: a gentle, even sound that many compare to steady rain or wind in the trees.
What people use it for
- Sleep: a middle ground for people who find white noise too sharp and brown noise too muffled.
- Focus: a steady background for reading, studying or working.
- Audio: sound engineers use it to test and tune speakers.
How to use it
Start low and stop turning up when the background noise disappears. Compare it with white and brown noise and keep the one you stop noticing. Mix it with other sounds in the web app.
