Noise (electronics) — Electronic noise [1] is a random fluctuation in an electrical signal, a characteristic of all electronic circuits. Noise generated by electronic devices varies greatly, as it can be produced by several different effects. Thermal noise is… … Wikipedia
Noise-canceling microphone — A noise canceling microphone is a microphone designed to filter out ambient noise from the desired sound, especially useful in noisy environments. Contents 1 Technical detail 2 Alternative technologies 3 Applications … Wikipedia
Perlin noise — is a procedural texture primitive, used by visual effects artists to increase the appearance of realism in computer graphics. This is a type of Gradient noise. The function has a pseudo random appearance, yet all of its visual details are the… … Wikipedia
Value noise — is a type of noise commonly used as a procedural texture primitive in computer graphics. It is conceptually different, and often confused with gradient noise examples of which are the Perlin noise and Simplex noise. This method consists of a… … Wikipedia

Roadway noise — is the collective sound energy emanating from motor vehicles. In the USA it contributes more to environmental noise exposure [Senate Public Works Committee, Noise Pollution and Abatement Act of 1972, S. Rep. No. 1160, 92nd Cong. 2nd session] than … Wikipedia
Simplex noise — is a method for constructing an n dimensional noise function comparable to Perlin noise ( classic noise) but with a lower computational overhead, especially in larger dimensions. Ken Perlin designed the algorithm in 2001 [Ken Perlin, Noise… … Wikipedia
