Acoustic metamaterial
ID: acoustic-metamaterial
Acoustic metamaterials are engineered materials designed to manipulate sound waves in innovative ways that conventional materials cannot. These metamaterials typically have unique structural features that allow them to control sound propagation, including its speed, direction, and frequency. Key characteristics of acoustic metamaterials include: 1. **Negative Refraction**: They can bend sound waves in ways that are counterintuitive, such as reversing their direction.
