Vibration

Vibration is the backward and forward movement of a body. Sound is caused by vibration that makes particles in the air form sound waves. A damper is used to reduce vibration. Vibration is the backward and forward movement of a body.

Pitch

Pitch can be taken as the measure of sound frequency expressed in terms of Hertz. Higher the frequency, higher the pitch and vice versa.

Amplitude

The amplitude of a sound wave is the measure of the height of the wave. The amplitude of a sound wave can be defined as the loudness or the amount of maximum displacement of vibrating particles of the medium from their mean position when the sound is produced.

Frequency

Frequency, sometimes referred to as pitch, is the number of times per second that a sound pressure wave repeats itself.

Oscillation

An oscillation is a back and forth motion of an object between two points of deformation. An oscillation may create a wave, which is a disturbance that spreads from where it was created.

Wave

A sound wave is the pattern of disturbance caused by the energy travelling away from the source of the sound. Sound waves are created by object vibrations and produce pressure waves, for example, a ringing cellphone.

Loudness

The loudness of a sound is a phenomenon that occurs when the amplitude of the sound wave changes. The sound is said to be loud if the amplitude of the sound wave is large. The loudness of sound is proportional to the square of the vibration amplitude and is measured in decibels.

Intensity

Sound intensity, also known as acoustic intensity, is defined as the power carried by sound waves per unit area in a direction perpendicular to that area. The SI unit of intensity, which includes sound intensity, is the watt per square meter.

Wavelength

Wavelength is the distance from one crest to another, or from one trough to another, of a wave. In simple language, wavelength is the distance or length of waves.
