white noise (uncountable)

    • 2005, John G. Holden, [https://web.archive.org/web/20101225100253/http://www.nsf.gov/sbe/bcs/pac/nmbs/chap6.pdf Gauging the Fractal Dimension of Response Times from Cognitive Tasks]
      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.
  2. (nontechnically) Any nondescript noise used for background or to mask or drown out other noise.
