Oblique room modes depend on all three dimensions

Evidence

These modes occur between all six surfaces, as shown in Figure 6.34, and so are a function of all three dimensions of the room. The frequencies of the oblique modes are given by the following equation: where fxyz(oblique) = the oblique modal frequencies (in Hz) x, y, z = the number of half wavelengths between the surface (1, 2, . — David M.

Categorization

• DEFINE: Clarifies that oblique modes arise from all six surfaces, differentiating them from axial and tangential modes.
• corroborated: 2 independent passages support this claim — David M. Howard, Jamie Angus, Acoustics and Psychoacoustics, 1968
