sci.room-mode-Schroeder-frequency Calculator
Calculates the Schroeder frequency f_s = 2,000√(RT60/V), below which individual room modes dominate and above which statistical room acoustics apply. A 100 m³ room with RT60 = 0.5 s has f_s = 141 Hz — below f_s, bass treatment targets individual modal peaks rather than broadband absorption.
Inputs
V M3
Three-dimensional space occupied (m³ or L). 1 m³ = 1,000 L.
Rt60 S
Duration of the process. Make sure units match the rate inputs (seconds, minutes, or hours).
Results
Schroeder frequency f_S (Hz)
Sample size or count used in the calculation.
wavelength at f_S (m)
The computed linear length.
modal density at f_S (modes/Hz)
The most frequently occurring value.
f_S = 2000·√(RT60/V)
Reference formula or conversion factor shown for context.
acoustic treatment
The value at the specified point or condition.
room ratio optimization
The proportional relationship between two quantities.
