The 30 pages that link to Amplitude, each with the reason it gives.

• WavelengthCompared with: It describes wave magnitude, not the distance between repeating points.

• Signal-to-noise ratioRelated: Amplitude ratios require squaring when converted to power ratios under equal impedance.

• Simple harmonic motionRelated: It sets the largest excursion, without changing the period in ideal linear motion.

• BioacousticsRelated: Amplitude relates to signal strength and perceived loudness.

• Digital audioRelated: Sample values encode waveform amplitude, which relates to sound pressure and loudness.

• Standing waveRelated: It describes the maximum motion at standing-wave antinodes.

• Amplitude modulationRelated: AM encodes information in changes to this wave property.

• Musical instrumentRelated: Players control loudness by changing how strongly an instrument vibrates or signals are amplified.

• InterferenceRelated: The amplitudes of overlapping waves determine the resulting signal strength.

• SoundRelated: Wave amplitude relates to sound pressure and often to perceived loudness.

• Phase (waves)Compared with: Amplitude sets waveform size, whereas phase sets its position within the cycle.

• PhasorRelated: A phasor’s magnitude commonly records the sinusoid’s amplitude, though RMS conventions also occur.

• Spatial frequencyRelated: Amplitude sets pattern contrast, independently of how closely spaced cycles are.

• Acoustic communicationRelated: Signal amplitude affects loudness and the distance at which a sound can be detected.

• OscillationRelated: Amplitude measures how far an oscillation reaches from equilibrium.

• Analog signalRelated: An analog signal carries information in continuously varying magnitude.

• PsychoacousticsRelated: Amplitude contributes to sound pressure and, in turn, perceived intensity.

• Auditory systemRelated: Sound amplitude contributes to perceived loudness.

• Gaussian functionRelated: The leading constant sets the Gaussian's peak height.

• Auditory perceptionRelated: Amplitude contributes to perceived loudness, though the relation is not linear.

• Sound pressureRelated: Sound-pressure amplitude describes the size of pressure fluctuations.

• Acoustic phoneticsRelated: It measures pressure variation associated with acoustic intensity.

• Audio signalRelated: Signal amplitude relates to sound pressure level and perceived loudness.

• Wave interferenceRelated: The amplitudes being combined determine the strength of the resultant wave.

• VocalizationRelated: Amplitude relates to signal intensity and how far a vocalization may carry.

• WaveformRelated: Waveform height represents amplitude, though the reference level determines how that height is measured.

• EarRelated: Sound amplitude contributes to perceived loudness and determines mechanical input to the ear.

• Mechanical waveRelated: For a mechanical wave, amplitude measures the size of the medium’s local disturbance.

• Seismic magnitude scalesRelated: Several traditional magnitude scales use recorded wave amplitude as their central measurement.

• Energy (signal processing)Compared with: A peak amplitude alone does not account for a signal’s duration.
