Teaching-learning-based optimization of a composite metastructure in the 0–10 kHz broadband sound absorption range

This paper proposes a strategy to broaden the sound absorption region of porous materials by embedding ribs. The theoretical solution and the numerical simulations of the optimization model show that the composite metastructure exhibits ultra-wide high absorption characteristics and an average sound...
