The measure of the sound energy of a wave is called what?

Explanation:
Intensity is the measure of the energy carried by a sound wave per unit area per unit time. It grows with the amplitude of the pressure fluctuations, so larger amplitudes mean more energy and a higher intensity, which typically makes the sound seem louder. Pitch is about frequency, not energy. Loudness is our perception of how strong a sound seems, which can vary with the listener and environment. Quality (timbre) involves the waveform’s shape and harmonic content, not how much energy the wave carries. Thus, intensity correctly describes the energy aspect of a sound wave.
