White noise generators have their places. They commonly get used as sleep machines, or sometimes in offices to cover conversation or other environmental noise. There have been iOS apps that have generated white noise in the past, but not like this.

Silence seems to be a productivity killer. So does TV or lyrics with noise. Running a noise generator like this in the background may be just the thing you need.
