White Noise

Generates non-repeating "white noise" to mask sounds that disturb your sleep or concentration.

This tool is used to mask disturbing background noises, with a generated random noise so-called white noise similar to static. White noise is useful to light sleepers by masking noises such as snoring or traffic noise. It can be helpful to those suffering from forms of tinnitus e.g. ringing in the ears. It may also serve as background noise in quiet office environments, improving concentration.

Unlike many other such apps, this one does not play a mere "canned" recording, because most people will eventually perceive the repetition of such a sound as quite disturbing. The noise produced is generated on-the-fly using a pseudo-random number generator and is adjustable using a tone control filter to produce a masking sound best suited to the conditions.

A preferences top-swipe menu allows the user to:
control whether the sound continues when the app is inactive
disable the animations to minimize CPU usage and power consumption

In the default configuration, the app will allow the screen to blank but will continue generating sound even when your BlackBerry PlayBook goes "to sleep". Details of use are available by tapping on the "?" button.
