Dedecahedral speaker array
This page describes some work at CNMAT on a dodecahedral loudspeaker array. This array was built by Edgar Berdahl and Thomas Harder as supervised by David Wessel and Adrian Freed. Each loudspeaker is controlled independently to synthesize complex sound fields that emulate those of real acoustic musical instruments. Since then, the work has been extended into a 120-channel system. Please see CNMAT's website for more information on the resulting publications and additional collaborators.
Below the final product can be seen on a stand from Universal Support, where it is being eyed by
Professor David Wessel. The speaker has been used for many concerts as well as experiments on sound cancellation and radiation pattern programming.
