White Noise 3D - Nature Music Hypnotic Lullaby para Android

11 detalles sobre White Noise 3D - Nature Music Hypnotic Lullaby

1. In order to ensure a balanced effect Venue concerts or other performances, it issued a white noise or pink noise from the PA system instantly, and in a different place to monitor the noise signal, so that engineers can effect a building acoustics can automatically enlarge or cut certain frequencies, which can be adjusted to give effect overall balance a balanced harmony.

2. In electronic music also applied white noise, which is directly or as the input signal of the filter to produce other types of noise signals, especially in audio synthesis, often like cymbals for reproducing a high frequency domain so that percussion noise components.

3. 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.

4. Refers to white noise in a wide frequency range, the energy of each frequency band included in the noise and other noise equivalent bandwidth.

5. 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.

6. One application is the white noise of architectural acoustics, in order to weaken the internal space distracting and do not want the noise (such as conversation human) appears, use continuous low-intensity noise as background sound.

7. For example, thermal noise and shot noise over a wide frequency range with a uniform power spectral density can usually think they are white noise.

8. In fact, we often limited bandwidth of the signal level regarded as white noise, because it makes us more convenient in mathematical analysis.

9. White noise can be used for frequency response of the filter amplifier or electronic test, sometimes it is used with a flat response microphone or automatic equalizer.

10. White noise or white noise is a constant power spectral density of random signals or random process.

11. Ideal white noise has infinite bandwidth, so its energy is infinite, which is impossible in the real world exists.
