Absorption coefficient (acoustics)
The sound absorption coefficient is the fraction of incident sound energy a surface absorbs, measured by standardized reverberation-room tests and used in room acoustics design and noise control.
Reverberation
Reverberation is the persistence of sound in an enclosed space after the source stops, produced by many reflections; it is measured by reverberation time (RT60).
Soundscape
A soundscape is the acoustic environment as perceived and understood by people in context, treating sound as a resource to design rather than noise to reduce.
