Origin: Middle English, from Old French, perhaps from Vulgar Latin *nausea, discomfort, from Latin nausea, seasickness; see nausea.Word History: Those who find that too much noise makes them ill will not be surprised that the word noise can possibly be traced back to the Latin word nausea, “seasickness, feeling of sickness.” Our words nausea and noise are doublets, that is, words borrowed in different forms from the same word. Nausea, first recorded probably before 1425, was borrowed directly from Latin. Noise, first recorded around the beginning of the 13th century, came to us through Old French, which explains its change in form. Old French nois probably also came from Latin nausea, if, as seems possible, there was a change of sense during the Vulgar Latin period, whereby the meaning “seasickness” changed to a more general sense of “discomfort.” Word meanings can sometimes change for the better, and nowadays, of course, a noise does not have to be something unpleasant, as in the sentence “The only noise was the wind in the pines.”

noise - Computer Definition
Unwanted disturbances superimposed on a signal and interfering with its integrity. Noise can be introduced by equipment or can be the result of natural phenomena. Noise can take a number of forms, including amplitude noise, cross-talk, echo, intermodulation noise, harmonic distortion, impulse noise, random noise, and white noise.
(1) Extraneous, unwanted signals that invade an electrical or optical system. In electronics, noise can come from strong electrical or magnetic signals in nearby lines, from poorly fitting electrical contacts and from power line spikes. In optics, noise comes from the stray reflections of light that emanate from the various components in the optical system. See signal-to-noise ratio and noise cancellation.
(2) Distortions in analog and digital video images that are caused by a variety of circumstances. The silver grains in the original film create granular noise. Electronic circuits create Gaussian noise. Drop outs and bit errors in digital tapes create impulse noise, and the digitization process creates quantization noise. See Gaussian noise, dynamic noise reduction and artifact.
(3) Distortions in a still image caused by variations in the pixels in the CCD or CMOS sensor. See digital camera.
