In sound, amplitude refers to the magnitude of compression and expansion experienced by the medium the sound wave is travelling through. This amplitude is perceived by our ears as loudness. High amplitude is equivalent to loud sounds. Two graphs showing the difference between sound waves with high and low amplitude e

When the sound waves reach the ear, they are translated into electrical impulses. amplitude, sound intensity and its direction from which the sound is coming.

With sound waves, it is the extent to which air particles are displaced, and this amplitude of sound or sound amplitude is experienced as the loudness of sound. With sound waves, amplitude measures the amount of positive or negative change in atmospheric pressure caused by the wave. If the sound wave has a greater amplitude, it will cause a greater change in atmospheric pressure. This can be changed by changing the amount of force of the current. Amplitude is the size of the vibration, and this determines how loud the sound is. We have already seen that larger vibrations make a louder sound.

Pressure amplitude has units of pascals (Pa) or N/m 2. Note that Δp is half the difference between the maximum and minimum pressure in the sound wave. We can see from the equation that the intensity of a sound is proportional to its amplitude squared.

The [-1 1] range for digital audio signals is convention. The range is discrete and the number of steps in it depends on the bit resolution of the signal. For different bit resolutions, the minimum and maximum are still -1 and 1. Scientists often draw sound waves as wavy lines, like these graphs. The taller the waves in the line, the louder the sound is. The height of the wave is called the amplitude. Pitch has to do with how high or low a sound is (frequency).

Amplitude describes the height of the sound pressure wave or the “loudness” of a sound and is often measured using the decibel (dB) scale.

Amplitude is the fluctuation or displacement of a wave from its mean value. With sound waves, it is the extent to which air particles are displaced, and this amplitude of sound or sound amplitude is experienced as the loudness of sound.

The amplitude of a SOUND WAVE is the maximum amount by which the instantaneous SOUND PRESSURE differs from the AMBIENT pressure. See diagram Loudness depends on the amplitude of the sound wave. But the perceived loudness varies from person to person! •We don't have a uniform frequency response The differences between sounds are caused by intensity, pitch, and tone. Intensity. Sound is a wave and waves have amplitude, or height.
