🔊 Acoustic Metamaterials Explained

An interactive 3D lattice of engineered sub-wavelength resonators where adjusting unit-cell geometry creates simulated bandgaps that block specific sound frequencies from passing through the material.

Acoustics2DAdvanced60 FPS

A 3D lattice of engineered sub-wavelength resonators embedded in a host structure, where each unit cell's own resonance can absorb and reflect a chosen band of sound frequencies before they reach the far side.

🔬 What It Demonstrates

Locally resonant metamaterials create a bandgap set by resonator mass and coupling stiffness, not by lattice thickness — inside that band, wave amplitude decays exponentially cell to cell instead of propagating.

🎮 How to Use

Sweep the drive frequency through the lattice, then retune the resonator mass and coupling stiffness to move and widen the purple bandgap on the strip chart, watching the 3D wave die out or pass through in real time.

💡 Did You Know?

Because resonance — not slab thickness — sets the blocked frequency, acoustic metamaterials can attenuate wavelengths many times longer than the material itself, beating the classic mass-law limit of conventional soundproofing.
