Vibration is a mechanical phenomenon whereby oscillations occur about an equilibrium point.
Pitch is a perceptual property that allows the ordering of sounds on a frequency-related scale.
Amplitude is the objective measurement of the degree of change (positive or negative) in atmospheric pressure (the compression and rarefaction of air molecules) caused by sound waves.
Frequency is the number of occurrences of a repeating event per unit time.
Oscillation is the repetitive variation, typically in time, of some measure about a central value (often a point of equilibrium) or between two or more different states.
A wave of compression and rarefaction, by which sound is propagated in an elastic medium such as air.
Loudness is the characteristic of a sound that is primarily a psychological correlate of physical strength (amplitude)
A sound particle is an imaginary infinitesimal volume of a medium that shares the movement of the medium in response to the presence of sound at a specified point or in a specified region.
Sound intensity is defined as the sound power per unit area.
