Galileo wrote " Waves are produced by the vibrations of a sonorous body, which spread through the air, bringing to the tympanum of the ear a stimulus which the mind interprets as sound ", a remarkable statement that points to the beginnings of physiological and psychological acoustics.

What we experience as " higher pitched " or " lower pitched " sounds are pressure vibrations having a higher or lower number of cycles per second.

These are made from special ceramics in which mechanical vibrations and electrical fields are interlinked through a property of the material itself.

When compressed, the crystal produces a small electrical current, so when placed under the bridge saddle, the vibrations of the strings through the saddle, and of the body of the instrument, are converted to a weak electrical signal.

For example, in crystalline solids, these correspond to phonons, which are quantized versions of lattice vibrations.

These weaker springs are compressed solely by the radial vibrations from an idling engine.

Even though the clutch may physically be located very close to the pedal, such remote means of actuation are necessary to eliminate the effect of vibrations and slight engine movement, engine mountings being flexible by design.

Cyclic processes that are not electrical in nature, such as the rotation rate of a shaft, mechanical vibrations, or sound waves, can be converted to a repetitive electronic signal by transducers and the signal applied to a frequency counter.

Pickups are transducers attached to a guitar that detect ( or " pick up ") string vibrations and convert the mechanical energy of the string into electrical energy.

They are the source of virtually all sinusoidal vibrations and waves.

As the key reaches its rest position, the string's vibrations are halted by the damper, a piece of felt attached to the top of the jack.

Karmas are attracted to the karmic field of a soul due to vibrations created by activities of mind, speech, and body as well as various mental dispositions.

:* Textile reinforced materials – materials in the form of ceramic or concrete are reinforced with a primarily woven or non-woven textile structure to impose high strength with comparatively more flexibility to withstand vibrations and sudden jerks.

These vibrations are transmitted through a bridge to a sounding board that more efficiently couples the acoustic energy to the air.

Composite materials are not preferred by top players, because the shaft of composite mallets can't absorb vibrations as well as traditional cane mallets.

Repetitive strain injuries ( RSIs ) are " injuries of the musculoskeletal and nervous systems that may be caused by repetitive tasks, forceful exertions, vibrations, mechanical compression ( pressing against hard surfaces ), or sustained or awkward positions ".. RSI is also known as cumulative trauma disorders, repetitive stress injuries, repetitive motion injuries or disorders, musculoskeletal disorders, and overuse syndromes.

In the first STM by Binnig and Rohrer, magnetic levitation was used to keep the STM free from vibrations ; now mechanical spring or gas spring systems are often used.

String theories that include fermionic vibrations are now known as superstring theories ; several kinds have been described, but all are now thought to be different limits of M-theory.

While 60 ° V6 engines are not as well balanced as inline-6 and flat-6 engines, modern techniques for designing and mounting engines have largely disguised their vibrations.

If huge quantities of anti-metal are gathered together, the vibrations increase exponentially.

Waves in crystalline solids are not continuous, because they are composed of vibrations of discrete particles arranged in a regular lattice.

Large crystal vibrations will generate heat in the metal and are detectable because of a change in resistance.

These epidermal ridges serve to amplify vibrations triggered, for example, when fingertips brush across an uneven surface, better transmitting the signals to sensory nerves involved in fine texture perception.

In the automotive industry, for example, it damps the vibrations between interior panels and also stops dirt entering into some ball / cup joints.

For example, the service life of bearings in one application was extended dramatically by changing how the bearings were stored before installation and use, as vibrations during storage caused lubricant failure even when the only load on the bearing was its own weight ; the resulting damage is often false brinelling.

For most wave fields ( for example, sound waves and the vibrations of strings and membranes ) such a description is an idealization which is valid for distances larger than the characteristic length which measures the granularity of the medium.

For example, Athena's wisdom is different from Solomon's, allowing Mary to perceive " life vibrations " and distinguish between living and non-living beings.

This movement allows the suspension parts to move freely, for example, when traveling over a large bump, while minimizing transmission of noise and small vibrations through to the chassis of the vehicle.

In piston engine engineering, a balance shaft is an eccentric weighted shaft which offsets vibrations in engine designs that are not inherently balanced ( for example, most four-cylinder engines ).

Motorists that may have loud music playing in their car, for example, may not hear the audible siren of a police car behind them, but will feel the vibrations of the Rumbler.

For example the southern European Chrysoperla mediterranea looks almost identical to its northern relative C. carnea ( Common Green Lacewing ), but their courtship " songs " are very different ; individuals of one species will not react to the other's vibrations, Oligochrysa, Synthochrysa )

For example, an orientation change of a beam could reduce the maximum stress or strain level, while a shape change could render a structure less susceptible to dynamic vibrations.

For example, in conductive liquids such as salt water, " ion-drag " causes heating, as charged ions are " dragged " more slowly back and forth in the liquid under influence of the electric field, striking liquid molecules in the process and transferring kinetic energy to them, which is eventually translated into molecular vibrations and thus into thermal energy.

For example, by using " solid light vibrations ," essentially resonating the target's inner ear, he was able to approximate telepathic communication.

By measuring the intensity of the same reflections at two temperatures ( for example, at a room and a high temperature ) one can calculate mean-square amplitudes of the atom vibrations.

For example, two large engines running at slightly different speeds will send " surges " of vibrations through the deck of a ship or jet plane.

Molecular dynamics ( MD ) use either quantum mechanics, Newton's laws of motion or a mixed model to examine the time-dependent behavior of systems, including vibrations or Brownian motion and reactions.

Resonance phenomena occur with all types of vibrations or waves: there is mechanical resonance, acoustic resonance, electromagnetic resonance, nuclear magnetic resonance ( NMR ), electron spin resonance ( ESR ) and resonance of quantum wave functions.

Often referred to as a quasiparticle, it represents an excited state in the quantum mechanical quantization of the modes of vibrations of elastic structures of interacting particles.

Around that time, he formed a group of young scientists to work on radiospectroscopy of molecular rotations and vibrations, and later on quantum electronics.

* Vlatko Vedral of the University of Leeds and colleagues at the universities of Porto and Vienna found that the photons in ordinary laser light can be quantum mechanically entangled with the vibrations of a macroscopic mirror.

In the classical system, the coupling produces two modes, one of which is lower in frequency than either of the uncoupled vibrations ; quantum mechanically, this lower frequency is interpreted as a lower energy.

The energy eigenstates of the linear harmonic oscillator ( e. g., masses on springs, lattice vibrations in a solid, vibrational motions of nuclei in molecules, or oscillations in the electromagnetic field ) are fixed-number quantum states.

It treats the vibrations of the atomic lattice ( heat ) as phonons in a box, in contrast to the Einstein model, which treats the solid as many individual, non-interacting quantum harmonic oscillators.

* Leon Gunther †‡ lattice vibrations in alkali halides, later Professor of Physics at Tufts University, focus on condensed matter theory in many areas, including superconductivity and seminal papers on nanoscopic physics & quantum tunneling of magnetization.

Raman-active vibrations / rotations can be identified by using almost any textbook that treats quantum mechanics or group theory for chemistry.
