Acoustic Affordance
/əˈkuːstɪk əˈfɔːrdəns/
ETYMOLOGY
Greek akoustikos (of hearing) + Old English afford (to provide, make available)
COINED BY
The Chromologium Archives
The use of synthesized audio feedback as a functional communication channel—not decorative accompaniment—where waveform, harmonic interval, and ADSR envelope encode the semantic weight and outcome of an interface action.
A success action produces an ascending perfect fifth with fast attack; an error produces a descending minor third with slow decay. Each Visual Movement tunes its own acoustic palette to match its spatial atmosphere.
“Sound in an interface is not ornamentation; it is the voice of the machine acknowledging the human.”
