Abstract

We show with experiments in a very complex reverberating room, we are able to achieve versatile control of sound fields by only modifying the room reverberating properties using a “spatial sound modulator” (SSM), which is an actively tunable metasurface for acoustic sound. We show the on-demand creation “quiet zones” or “hot spots”, which shows the potential to improve quality of life in everyday situations.
