sci.room-mode-frequency Calculator
Calculates axial, tangential, and oblique room modes from room dimensions: f = c/2 × √(nx/Lx)²+(ny/Ly)²+(nz/Lz)². Ideal rooms avoid equal dimensions — the golden ratio dimensions (1:1.618:2.618) spread modes most evenly, reducing severe bass peaks and nulls.
Inputs
L M
Linear measurement. Ensure consistent units: 1 m = 1,000 mm = 3.281 ft.
W M
Horizontal extent perpendicular to the length.
H M
Vertical measurement. For health calculators, typically standing height without shoes.
P
Reference formula or conversion factor shown for context.
Q
Reference formula or conversion factor shown for context.
R
Reference formula or conversion factor shown for context.
Results
room mode frequency (Hz)
The most frequently occurring value.
axial mode — length (Hz)
The computed linear length.
axial mode — width (Hz)
The computed width.
axial mode — height (Hz)
The computed height.
mode type
The most frequently occurring value.
f = c/2 · √((p/L)²+(q/W)²+(r/H)²)
