For simple [[periodic]] [[wave]]s, the '''Root Mean Square amplitude''' is equal to the [[peak]] amplitude multiplied by 0.707. For complex periodic waves, RMS amplitude cannot be derived directly from peak measurements. Peak measurements differ from RMS amplitude in that they give a measure of acoustic amplitude, whereas RMS amplitude is a measure of acoustic [[intensity]] (because perceived loudness is linked more closely to acoustic intensity than to acoustic amplitude). To calculate RMS amplitude, each sample in a waveform window is squared; then the average of the squares is calculated; and then, the square root is taken.<br />
