Researchers design an elastic structure with optimal topology to mask the location of a sound source

Caption

Overcoming the challenges in realizing a high-performance acoustic source-shifter, Prof. Garuda Fujii from Shinshu University in Japan developed an elastic structure for location camouflage. (a) Optimal sound source-shifter made of acrylonitrile butadiene styrene, (b) Sound pressure around the source-shifter, and (c) Difference between the emitted pressure field and the ideal field, which is minimized outside the source-shifter.
