The world is a loud place and it can be hard to focus your thoughts when you’re surrounded by so much noise. Total silence can be a bit much too. If you need some background sound that won’t drag your attention away from your tasks, check out Simply Noise, the white noise generator.

This website does one thing. Generates background noise That’s all. No graphics, no extras, just nondescript sound. Well, it sounds a bit like static but static is pretty nondescript. The noise comes in three flavors, white, pink, and the unfortunately named brown noise.

Each version is slightly different from the other and although the site lists the sounds perfect uses, it also recommends listener choose the noise that works for them. This website also has a sleep timer so you can use it to help you fall asleep without leaving it on all night. It can be used to calm children down, help you focus and even soothe migraines. Simply Noise has a 99 cent mobile app but the website is free.
