Noise is the general word and is applied equally to soft or loud, confused or inharmonious sounds: street noises. Clamor and hubbub are alike in referring to loud noises resulting from shouting, cries, animated or excited tones, and the like; but in clamor the emphasis is on the meaning of the shouting, and in hubbub the emphasis is on the confused mingling of sounds: the clamor of an angry crowd; His voice could be heard above the hubbub. Din suggests a loud, resonant noise, painful if long continued: the din of a boiler works. Racket suggests a loud, confused noise of the kind produced by clatter or percussion: He always makes a racket when he cleans up the dishes. 2. See sound ¹ .

Babel stresses confusion of vocal sounds arising from simultaneous utterance and random mixture of languages: guests chattering in a babel of tongues at the diplomatic reception.

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."

Language Translation for : noise

Spanish: ruido, sonido,

German: das Geräusch,

Japanese: 音

More Translations »

noise

c.1225, "loud outcry, clamor, shouting," from O.Fr. noise "uproar, brawl" (in modern Fr. only in phrase chercher noise "to pick a quarrel"), apparently from L. nausea "disgust, annoyance, discomfort," lit. "seasickness" (see nausea). Another theory traces the O.Fr. word to L. noxia "hurting, injury, damage." OED considers that "the sense of the word is against both suggestions," but nausea could have developed a sense in V.L. of "unpleasant situation, noise, quarrel" (cf. O.Prov. nauza "noise, quarrel"). Replaced native gedyn (see din).

Noise

Price and volume fluctuations in the market that can confuse one's interpretation of market direction. Used in the context of equities, it is stock market activity caused by program trading, dividend payments or other phenomena that is not reflective of overall market sentiment. Also known as "market noise".

Investopedia Commentary

In general, the shorter the time frame, the more difficult it is to separate the meaningful market movements from the noise. Noise traders attempt to take advantage of market noise by entering buy and sell transactions without the use of fundamental data.

Also spelled: Market Noise

noise

Random market fluctuations that make it difficult to forecast the market's direction.

noise communications
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.
