Tangential modes depend on two room dimensions rather than one

Evidence

These modes occur between four surfaces, as shown in Figure 6.32, and so are a function of two of the dimensions of the room. — David M. Howard, Jamie Angus, Acoustics and Psychoacoustics, 1960

These modes occur between four surfaces, as shown in Figure 6.32, and so are a function of two of the dimensions of the room. The frequencies of the tangential modes are given by the following equation: where fxy(tangential) = the tangential modal frequencies (Hz) x = the number of half wavelengths between one set of two sur- faces (1, 2, . — David M.

Categorization

• DEFINE: Distinguishes tangential room modes from axial ones by the number of dimensions involved.
• corroborated: 2 independent passages support this claim — David M. Howard, Jamie Angus, Acoustics and Psychoacoustics, 1960
