The mean free path in room acoustics
The mean free path of an enclosure – which is of practical use in diffuse sound fields – is shown to be four times the ratio of volume over surface (4 V/S). This holds without any approximation for all room shapes.
In the rather extensive literature on this important quantity a straightforward and simple derivation could not be found. Discrepancies from 4 V/S, reported in literature, are discussed and explained.
