Meanings
-
(uncountable) 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.
Conventional statistical analyses presuppose that intrinsic variability is white noise. White noise yields a jagged and irregular line with a fractal dimension of 1.5, because successive observations are statistically independent of each other.
2005, John G. Holden, Gauging the Fractal Dimension of Response Times from Cognitive Tasks:
- (uncountable) Any nondescript noise used for background or to mask or drown out other noise.
-
(broadly, figuratively, uncountable) Speech that goes ignored or uncomprehended.
The rest was white noise; I was sick of listening to who I was supposed to be.
