Noise Definition from Science & Technology Dictionaries & Glossaries
Telecommunication Standard Terms
1. An undesired disturbance within the frequency band of interest; the summation of unwanted or disturbing energy introduced into a communications system from man-made and natural sources. (188 ) 2. A disturbance that affects a signal and that may distort the information carried by the signal. 3. Random variations of one or more characteristics of any entity such as voltage, current, or data. 4. A random signal of known statistical properties of amplitude, distribution, and spectral density. 5. Loosely, any disturbance tending to interfere with the normal operation of a device or system.
RF Electronics
An extraneous electrical disturbance tending to interfere with the normal reception of a transmitted signals. Undesired sound or sounds. Sounds which are non-periodic and generally have random pitch and loudness characteristics.
Web Dictionary of Cybernetics and Systems
refers not simply to audible sound but rather to any undesired information in a communication channel which is not part of the intended message. Thus, smudges on a printed page, static on a radio, "ghosts" on a television can be interpreted as noise according to this definition. Because noise is an evaluative term, it occurs only in the receiver. The channel does not know the difference. (Umpleby )
Unexplained variation in a communication channel, random error in the transmission of information. Noise is not merely auditory as in the static on radio but may also be visual as in a blurred picture. It may occur in any measurement process where one differentiates between related and unrelated variance , the latter being noise. The analogy between noise and thermodynamic entropy is suggested by the fact that in any communication process, noise can only increase and it does so at the expense of the amount of information transmitted from a sender to one or more receivers. information theory quantitatively decomposes the receivers' statistical entropy into a quantity of transmitted information and the quantity of noise. Noise is the logical complement of equivocation and undesirable from the receiver's perspective. (Krippendorff )
Technical English by wpv
Any undesired sounds, usually of different frequencies, resulting in an objectionable or irritating sensation.

Noise Definition from Computer & Internet Dictionaries & Glossaries
Internet Glossary
(1) In communications, interference (static) that destroys the integrity of signals on a line. Noise can come from a variety of sources, including radio waves, nearby electrical wires, lightning, and bad connections. One of the major advantages of fiber optic cables over metal cables is that they are much less susceptible to noise.

(2) In general, anything that prevents a clear signal or message from being transmitted. For example, you might hear someone complain of a lot of noise in a newsgroup, meaning that there are many superfluous messages that don't add anything to the discussion.

Digital Video (DV) & video edit terms / Eng2Eng v1.0 (web compilation)
A general term used in electronics to indicate any unwanted electrical signal, unrelated to the original signal. Video noise is generally manifested as snow, graininess, ghost images or picture static induced by external sources such as the national power-line grid, electric motors, fluorescent lamps, etc.

Noise is a variety of sound. It means any unwanted sound. Sounds, particularly loud ones, that disturb people or make it difficult to hear wanted sounds, are noise. For example, conversations of other people may be called noise by people not involved in any of them; any unwanted sound such as neighbours playing loud music, portable mechanical saws, road traffic sounds, or a distant aircraft in quiet countryside, is called noise.
