Low-frequency waterborne sound insulation by an acoustic metascreen with a metal chiral structure
Low sound speed or low-density materials can be used EVALUATION OF DISTAL UPPER EXTREMITY (DUE) MUSCULOSKELETAL DISORDERS BY STRAIN INDEX (SI) IN AN IRONWORK INDUSTRY as soft acoustic boundaries in water, potentially as low-frequency underwater sound insulation.This study uses a chiral structure to construct an acoustic metascreen with deep subwave
