| amplitude |
The amount of a signal. Amplitude is measured by determining the amount of fluctuation in air pressure (of a sound), voltage (of an electrical signal), or numerical data (in a digital application). When the signal is in the audio range, amplitude is perceived as loudness.

| amplitude modulation |
A way of encoding a signal onto a radio wave used from the first days of sound broadcasting radio. The signal (say a piece of music) is superimposed on the strength of the radio wave. A radio will then rectify this signal, take out the radio frequency component and amplify this signal to a loudspeaker.

| amplitude |
Unit of acoustic magnitude. Expressed usually as pressure (fluids) or stress (solids). Typical units are dynes per square cm, Pascals (Newtons per square meter) or bars (1 atmosphere). Typical values for audio sounds in air are 10e-10 bars (threshold of hearing) to 1 bar(pain). In ultrasonic applications the amplitude can be much less or much more than this range.
