Angling room walls changes resonance frequencies but cannot eliminate them

Evidence

However, these dimensions are not necessarily the only optimum ones for all room sizes. It is also important to realize that room modes are inherent in any structure that encloses the sound sources. This means that changing the shape of the room, for example by angling the walls, does not remove the resonances-it merely changes their frequencies from values that are easily calculated to ones that FIGURE 6. — David M.
