Calculation

Based on the following equation:

F = (c/2) * sqrt((p/L)^2 + (q/W)^2 + (r/H)^2)

where: F = Mode center frequency
c = speed of sound
p = length mode number
q = width mode number
r = height mode number

Using the following approximation for the Schroeder frequency:

S = 3c/d

where: S = Schroeder frequency
c = speed of sound
d = the smallest representive dimension of the room
