   Note: Noise is either a sound of too short a duration to be
         determined, like the report of a cannon; or else it is
         a confused mixture of many discordant sounds, like the
         rolling of thunder or the noise of the waves.
         Nevertheless, the difference between sound and noise is
         by no means precise. --Ganot.

      din.

            which has made so much noise in all ages.
                                                  --Spectator.

   4. Music, in general; a concert; also, a company of
      musicians; a band. [Obs.] --Milton.

            The king has his noise of gypsies.    --B. Jonson.

   Syn: Cry; outcry; clamor; din; clatter; uproar.

noise
     
         Any part of a signal that is not the true or
        original signal but is introduced by the communication
        mechanism.
     
        A common example would be an electrical signal travelling down
        a wire to which noise is added by inductive and capacitive
        coupling with other nearby signals (this kind of noise is
        known as "{crosstalk}").
     
        A less obvious form of noise is {quantisation} noise, such as
        the error between the true colour of a point in a scene in the
        real world and its representation as a {pixel} in a digital
        image.
