Noise refers to many types of random, troublesome, problematic, or unwanted signals .
Acoustic noise may mar aesthetic experience, such as attending a concert hall. It may also be a medical issue inherent in the biology of hearing.
In technology, noise is unwanted signals in a device or apparatus, commonly of an electrical nature. The nature of noise is much studied in mathematics and is a prominent topic in statistics .
This article provides a survey of specific topics linked to their primary articles.

Noise in biology [ edit ]
Noise in computer graphics [ edit ]
Noise in computer graphics refers to various pseudo-random functions used to create textures, including:
Gradient noise , created by interpolation of a lattice of pseudorandom gradients
Simplex noise , a method for constructing an n
Simulation noise , a function that creates a divergence-free field
Value noise , created by interpolation of a lattice of pseudorandom values; differs from gradient noise
Wavelet noise , an alternative to Perlin noise which reduces problems of aliasing and detail loss
Worley noise , a noise function introduced by Steven Worley in 1996
Noise in electronics and radio [ edit ]
Noise in mathematics [ edit ]
Any one of many statistical types or colors of noise , such as
White noise , which has constant power spectral density
Gaussian noise , with a probability density function equal to that of the normal distribution
Pink noise , with spectral density inversely proportional to frequency
Brownian noise or "brown" noise, with spectral density inversely proportional to the square of frequency
Pseudorandom noise , in cryptography, artificial signal that can pass for random
Statistical noise , a colloquialism for recognized amounts of unexplained variation in a sample
Shot noise , noise which can be modeled by a Poisson process
Noise-based logic , where logic values are different stochastic processes
Noise print , a statistical signature of ambient noise, used in its suppression
Other types of noise [ edit ]
Measures of noise intensity [ edit ]
