- Reference wavelength (m)
- 3.430000
The empirical estimate is f = 2000 √(RT60 / volume), with seconds and cubic metres. Reference wavelength = 343 / f using a fixed sound speed of 343 m/s. This is an approximate transition region, not a sharp boundary or proof of a diffuse field. Use a representative measured RT60 for the room and frequency range. Geometry, damping distribution and actual measurements still matter; this does not calculate individual modes or design treatment.

The empirical estimate is f = 2000 √(RT60 / volume), with seconds and cubic metres. Reference wavelength = 343 / f using a fixed sound speed of 343 m/s.

Frequently asked questions
Does sound become diffuse exactly at this frequency?
No. The estimate marks a broad change in modal overlap. A single RT60 and volume cannot certify diffusion, measurement accuracy or treatment performance.
