Some people like to work in the cafe, but not in quiet library - some studies show that coffee shop environment will be more conducive to the sound focus, enhance creativity at work, this environment can be considered a kind of sound. white noise.

If you like listening to the rain, do not miss this application.

In addition to sound variety, also supports a variety of sound reverberation, and other custom scene.

Writing, running, travel time can be opened to listen!

It contains a variety of natural ambient sound.

Imitate the sounds of nature - this is the white noise (white noise), improve concentration, relaxation, fine.

Refers to white noise in a wide frequency range, the energy of each frequency band included in the noise and other noise equivalent bandwidth. Usually physically translate it into white noise (white noise). White noise or white noise is a constant power spectral density of random signals or random process. In other words, the signal power in each band is the same, since the white light is a mixture of various frequencies (colors) of monochromatic light, so that this signal has the nature of a flat power spectrum is called white, this signal has therefore been called white noise. Noise signal relative, other do not have this property are called colored noise. Ideal white noise has infinite bandwidth, so its energy is infinite, which is impossible in the real world exists. In fact, we often limited bandwidth of the signal level regarded as white noise, because it makes us more convenient in mathematical analysis. However, the white noise in the mathematical treatment is more convenient, so it is a powerful tool for system analysis. In general, as long as the spectral width of a noise process has the effect that it is much larger than the bandwidth of the system, and its spectral density can basically be considered as a constant in the bandwidth, you can use it as white noise to deal with. For example,
