Room mode is the human-made conceptual category for standing wave resonances that arise in enclosed spaces due to boundary reflections, parameterized by room dimensions, speed of sound, and mode order (axial, tangential, oblique), with frequencies f = (c/2) * sqrt((nx/Lx)^2 + (ny/Ly)^2 + (nz/Lz)^2). It persists through acoustic measurement protocols, architectural design guidelines, audio engineering curricula, and room correction software that identify and mitigate modes.

Definition
Why it is in scope

Room-mode as an acoustic concept is a specific application of resonance in enclosed spaces; the concept of resonance predates the specific acoustic room-mode construct.
- cmsoedhco01cyjlssnbvl8mz9INSTANCE_OF →
room-mode IS a type of resonance. A competent speaker would call a room mode 'a resonance' — specifically, a resonance pattern in an enclosed space. The note in the rejected DEPENDS_ON edge correctly said 'room modes ARE resonance phenomena' but used the wrong relation; this is INSTANCE_OF.
- cmsorsyn802qbjlss3cb2ruiyDEPENDS_ON →
Room-mode as an acoustic concept DEPENDS_ON frequency — a room mode is a standing wave pattern defined by its resonant frequencies. Remove frequency and room-mode ceases to operate: without frequency as a parameter, there is no concept of a standing wave pattern in an enclosed space.
