Web28 Jul 2024 · We’re squaring values, summing them, dividing by the number of values, and then taking the square root. There are only two differences between this procedure and the procedure that we use to calculate standard deviation: With RMS, we divide by N; with standard deviation, we (usually) divide by N–1. We can ignore this difference because the ... Web19 Feb 2016 · Similarly, the intensity of a wave is proportional to the square of the pressure. The same justification (given in an answer to the question I linked) implies that a wave with constant pressure equal to the RMS pressure of a given wave would have the same average intensity (over some time interval).
