  • Colors of noise
    In audio engineering, electronics, physics, and many other fields, the color of noise refers to the power spectrum of a noise signal (a signal produced by a stochastic process).
  • Noise pollution
    Noise pollution or noise disturbance is the disturbing or excessive noise that may harm the activity or balance of human or animal life.
  • Brownian noise
    User:RMCD bot/subject notice For similar phrases, see Brown note (disambiguation).
  • Dither
    Dither is an intentionally applied form of noise used to randomize quantization error, preventing large-scale patterns such as color banding in images.
  • Phonophobia
    Phonophobia, also called ligyrophobia or sonophobia, is a fear of or aversion to loud sounds—a type of specific phobia.
  • Thunder
    Thunder is the sound caused by lightning.
  • Salt-and-pepper noise
    Salt-and-pepper noise is a form of noise sometimes seen on images.
  • Interference (communication)
    In communications and electronics, especially in telecommunications, interference is anything which modifies, or disrupts a signal as it travels along a channel between a source and a receiver.
  • Mains hum
    Mains hum, electric hum, or power line hum is a sound associated with alternating current at the frequency of the mains electricity.
  • Moving-average model
    In time series analysis, the moving-average (MA) model is a common approach for modeling univariate time series.
  • The Mosquito
    (For other uses, see mosquito (disambiguation).) The Mosquito or Mosquito alarm is an electronic device used to deter loitering by young people by emitting sound at high frequency, in some versions so it can only be heard by younger people.
  • Tintamarre
    Tintamarre is an Acadian tradition of marching through one's community making noise with improvised instruments and other noisemakers, usually in celebration of National Acadian Day.
  • Noise in music
    In music, noise is variously described as unpitched, indeterminate, uncontrolled, loud, unmusical, or unwanted sound.
  • Pink noise
    Pink noise or  1⁄f noise is a signal or process with a frequency spectrum such that the power spectral density (energy or power per Hz) is inversely proportional to the frequency of the signal.
  • Noise (electronics)
    In electronics, noise is a random fluctuation in an electrical signal, a characteristic of all electronic circuits.
  • Signal-to-noise ratio
    Signal-to-noise ratio (abbreviated SNR or S/N) is a measure used in science and engineering that compares the level of a desired signal to the level of background noise.
  • Friis formulas for noise
    Friis formula or Friis's formula (sometimes Friis' formula), named after Danish-American electrical engineer Harald T.
