Optimization of Acoustic Metasurfaces with Hybrid Structures for attenuation of broadband low frequency sound: An exploratory research on hybrid metamaterials to analyze/uncover possible practical applications/benefits for sound attenuation

We perform a study on acoustic metasurfaces, aiming to achieve simultaneously low resonance frequencies (below 400 Hz), high attenuation bandwidth (greater than 200 Hz), and high attenuation coefficient magnitudes (above 0.8), while maintaining a surface-like structure.<br/>We propose the implementation of geometrical optimization through...
