Definition von white noise im Englisch Englisch wörterbuch: A random signal (or process) with a flat power spectral density; a signal with a power spectral density that has equal power in any band, at any centre frequency, having a given bandwidth; Any nondescript noise used for background or to mask or drown out other noise; White noise is a random signal (or process) with a flat power spectral density. In other words, the signal contains equal power within a fixed bandwidth at any center frequency. White noise draws its name from white light in which the power spectral density of the light is distributed over the visible band in such a way that the eye's three color receptors (cones) are approximately equally stimulated; A random noise used in measurements, as it has the same amount of energy at each frequency; A random-like signal with a flat frequency spectrum Doubling the bandwidth doubles the noise power and increases total noise voltage by the square root of two As opposed to pink noise, in which the frequency spectrum drops off with frequency White noise is analogous to white light, which contains every possible color White noise is normally described as a relative power density in volts squared per hertz White noise power varies directly with bandwidth, so white noise would have twice as much power in the next higher octave as in the current one The introduction of a white noise audio signal can destroy high-frequency loudspeakers; A full audio spectrum signal with the same energy level at all frequencies Compare with "Pink Noise "; By analogy with white light (composed of equal amounts of all visible light frequencies), white noise is a sound composed of an equal mix of all audible frequencies; a `sh' noise produced by a stimulus containing all audible frequencies of vibration; White noise is sound, especially of a loud, continuous, or unpleasant kind, that seems to have no pattern or rhythm. They were made to listen to white noise, such as static of the sort you might pick up between radio stations. Acoustical or electrical noise of which the intensity is the same at all frequencies within a given band. noise coming from a radio or television which is turned on but not tuned to any programme; An audio signal that contains noise at the same level at all frequencies; Noise having a frequency spectrum that is continuous and uniform over a specified frequency band (188) Note: White noise has equal power per hertz over the specified frequency band Synonym additive white gaussian noise; A random noise that contains an equal amount of energy per frequency band That is, 100-200, 800-900, and 3000-3100 Pink noise has an equal amount of energy per octave The bands 0-200, 800-1600, and 3000-6000 all contain the same amount of energy; Noise that results in a spectrum where all frequency components have the same amount of energy This can also refer the the resulting spectrum as well as the process Compare to red noise; A hiss-like sound formed by combining all audible frequencies; used in the ganzfeld experiment; mixture of sound waves extending over a wide frequency range that may be used to mask unwanted noise that may interfere with sleep; A sound or electromagnetic wave whose spectrum is continuous and uniform as a function of frequency; One source of data communication errors It results from the normal movements of electrons and is present in all transmission media at temperatures above absolute zero Also known as thermal noise or Gaussian noise; - Refers to background noise used to hide or block out other sounds; A combination of random noises in the transmission media caused by various electrical & magnetic sources A certain amount of White noise is inevitable in any transmission media; noise in the background, voice disturbances in a recording; A signal which contains all possible audio frequencies in equal average amplitudes Useful for testing equipment; Noise whose amplitude is constant throughtout the audible frequency range; A signal composed of all frequencies, which vary randomly in phase, each frequency having equal long-term energy levels; A random energy where there is an energy distribution so that the amount of energy is the same for each cycle, causing the noise level to increase with frequency
