Acoustic metamaterials

Acoustic metamaterials are specially designed materials engineered to control, direct, and manipulate sound waves in ways that natural materials cannot. They have unique structures at a small scale, allowing them to absorb, block, or focus sound with high precision. Applications include noise reduction, soundproofing, advanced ultrasound technologies, and acoustic cloaking—making objects less detectable by sound. Their innovative structure grants them extraordinary sound-manipulating properties, opening new possibilities in acoustics and wave control beyond what traditional materials can achieve.
