As a subcategory of acoustic metamaterials, membrane acoustic metamaterials (MAMs) are
lighter and more adjustable than other types of acoustic metamaterials when it comes to low …

The traditional sound absorption problem has not been completely resolved over the last
200 years. At every stage, its research has changed depending on practical requirements …

Many advanced physical properties can be realized by using well-designed acoustic
metamaterial (AM) structures, which have significant application value in engineering. In …

Over the past decade there has been a great amount of research effort devoted to the topic
of acoustic metamaterials (AMMs). The recent development of AMMs has enlightened the …

Local resonance metamaterials have garnered substantial interest in recent years due to
