Abstract
We present a novel approach for combating noise pollution by segmentation of monolithic plates into an assembly of topologically interlocked building blocks. The results of a study of the sound absorption in such segmented structures demonstrate a spectacular increase in the sound absorption coefficient over that in the original material (dental stone GC Fujirock). Measurements of the airflow resistance confirm the primary role of segmentation in imparting high sound absorption capability to the material, notably in the audible frequency range.
