... ARCHITECTURE Now it can be shown that the average value of the square of dP over one complete period is one-half the square of its maximum value. Hence, if we denote the square root of the mean square value of the pressure increment by p, Eq. (12) may be put in ... the tones of one octave of the tempered and physical scales. The frequencies and wave lengths given are for the first octav...
