Coupled Volumes: Secondary Room Reverberance and the Double-Sloped Decay of Concert Halls

The coupled volume concert hall and its signature double sloped sound decay aim to partially reconcile the often-competing qualities of clarity and reverberance. A concert hall is conceived with a fixed geometric volume, form, and aperture size. A coupled volume is attached and its materiality is established as variable. Both statistical and geometric relative analyses suggest a highly sensitive relationship between the coupled volume reverberation time and the double-sloped condition.
