Vibration \Vi*bra"tion\, n. [L. vibratio: cf. F. vibration.]

  1. The act of vibrating, or the state of being vibrated, or in vibratory motion; quick motion to and fro; oscillation, as of a pendulum or musical string.

    As a harper lays his open palm Upon his harp, to deaden its vibrations.

  2. (Physics) A limited reciprocating motion of a particle of an elastic body or medium in alternately opposite directions from its position of equilibrium, when that equilibrium has been disturbed, as when a stretched cord or other body produces musical notes, or particles of air transmit sounds to the ear. The path of the particle may be in a straight line, in a circular arc, or in any curve whatever.

    Note: Vibration and oscillation are both used, in mechanics, of the swinging, or rising and falling, motion of a suspended or balanced body; the latter term more appropriately, as signifying such motion produced by gravity, and of any degree of slowness, while the former applies especially to the quick, short motion to and fro which results from elasticity, or the action of molecular forces among the particles of a body when disturbed from their position of rest, as in a spring.

    Amplitude of vibration, the maximum displacement of a vibrating particle or body from its position of rest.

    Phase of vibration, any part of the path described by a particle or body in making a complete vibration, in distinction from other parts, as while moving from one extreme to the other, or on one side of the line of rest, in distinction from the opposite. Two particles are said to be in the same phase when they are moving in the same direction and with the same velocity, or in corresponding parts of their paths.

Douglas Harper's Etymology Dictionary

1650s, from Latin vibrationem (nominative vibratio) "a shaking, a brandishing," noun of action from past participle stem of vibrare "set in tremulous motion" (see vibrate). Meaning "intuitive signal about a person or thing" was popular late 1960s, but has been recorded as far back as 1899. Related: Vibrational.


n. 1 The act of vibrating or the condition of being vibrated. 2 (context physics English) Any periodic process, especially a rapid linear motion of a body about an equilibrium position. 3 A single complete vibrating motion. 4 (context slang English) An instinctively sensed emotional aura or atmosphere; vibes.

  1. n. the act of vibrating [syn: quiver, quivering]

  2. a distinctive emotional atmosphere; sensed intuitively; "it gave me a nostalgic vibe"; "that man gives off bad vibes" [syn: vibe]

  3. a shaky motion; "the shaking of his fingers as he lit his pipe" [syn: shaking, shakiness, trembling, quiver, quivering, palpitation]

  4. (physics) a regular periodic variation in value about a mean [syn: oscillation]

Vibration (radio)

Vibration is a French regional radio station, created in 1982 and owned by the Sud Radio Groupe.


Vibration is a mechanical phenomenon whereby oscillations occur about an equilibrium point. The word comes from Latin vibrationem ("shaking, brandishing"). The oscillations may be periodic, such as the motion of a pendulum—or random, such as the movement of a tire on a gravel road.

Vibration can be desirable: for example, the motion of a tuning fork, the reed in a woodwind instrument or harmonica, a mobile phone, or the cone of a loudspeaker.

In many cases, however, vibration is undesirable, wasting energy and creating unwanted sound. For example, the vibrational motions of engines, electric motors, or any mechanical device in operation are typically unwanted. Such vibrations could be caused by imbalances in the rotating parts, uneven friction, or the meshing of gear teeth. Careful designs usually minimize unwanted vibrations.

The studies of sound and vibration are closely related. Sound, or pressure waves, are generated by vibrating structures (e.g. vocal cords); these pressure waves can also induce the vibration of structures (e.g. ear drum). Hence, attempts to reduce noise are often related to issues of vibration.
