Highly efficient acoustic absorber designed by backing cavity-like and filled-microperforated plate-like structure

Crowded living conditions and increasingly severe noise problems necessitate the development of a low-thickness sound absorption material with remarkable sound absorption performance. Here, simple materials such as sodium alginate aerogel (SA) and polyurethane (PU) foam are used to combine with spec...
