Sound insulation properties of membrane-type acoustic metamaterials with petal-like split rings

Journal of Physics D: Applied Physics, 2021
Membrane-type acoustic metamaterials (MAMs) are lightweight and flimsy materials with excellent low-frequency insulation performance, which breaks the limitations of the traditional mass law and provides a new idea for noise reduction in the low ...

Sound Insulation Property of Warp Knitted Fabrics

Advanced Materials Research, 2012
In this study, a test device was designed and established for evaluating the sound insulation of fabrics, and six warp knitted fabrics with different parameters were chosen and tested. The results show that these fabrics have different sound insulation effect to various sound wave frequencies, and normally, the fabric with solid structure has better ...
