Freebase

  1. Noise

    In common use, the word noise means any unwanted sound. In physics and analog electronics, noise is a mostly unwanted random addition to a signal; it is called noise as a generalisation of the acoustic noise heard when listening to a weak radio transmission with significant electrical noise. Signal noise is heard as acoustic noise if the signal is converted into sound; it manifests as "snow" on a television or video image. High noise levels can block, distort, change or interfere with the meaning of a message in human, animal and electronic communication. In signal processing or computing noise can be considered random unwanted data without meaning; that is, data that is not being used to transmit a signal, but is simply produced as an unwanted by-product of other activities. "Signal-to-noise ratio" is sometimes used to refer to the ratio of useful to irrelevant information in an exchange. In biology, many different forms of cellular noise exist, where a measurement displays substantial variance around its mean: for example, transcriptional noise describes the variability in gene activity between cells in a population. In many cases, the special case of thermal noise arises, which sets a fundamental lower limit to what can be measured or signaled and is related to basic physical processes described by thermodynamics, some of which are expressible by simple formulae.

Examples of noise in a Sentence

  1. Bob Nicholls:

    I told everyone that we were going to go down the stairs very quietly. But with 150-odd people on a staircase, we were like sitting ducks. Two of my guys went ahead to make sure it was safe, we had two guys at the back. We'd move down to one floor, check the floor and then get everyone down. We did the same on the next floor. It took quite a while to get everyone down. We got out at around 3 or 4 in the morning, we were asked to take off our shoes to avoid making noise because we never knew if there were still terrorists around who could hear us. No one spoke either.
