Noise may arise in signals of interest to various scientific and technical fields, often with specific features: • Noise (audio), such as "hiss" or "hum", in audio signals • Noise (video), such as "snow" • Noise (radio), such as "static", in radio transmissions WebSignal-to-noise ratio is an important and widely used metric for determining the confidence with which one can quantify a signal of a given value, especially a signal near background. The confidence in quantifying the signal increases as the variation in background signal (the ‘noise’) decreases, regardless of the absolute value of the mean background.
