Amplitude is directly related to the acoustic energy or intensity of a sound. ... amplitude of a wave over time, called the root-mean-squared or rms method.

What is amplitude? Amplitude particle displacement how to calculate


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.

Amplitude & Intensity of Sound Waves


For sound waves: p. 0 is the pressure amplitude and s. 0 is the displacement amplitude. The intensity of sound waves also follow an inverse square law. m m.
