Witryna27 gru 2024 · Phononic crystals (PCs) have recently been developed as effective components for vibration suppression and sound absorption. As a typical design of PCs, wave attenuation occurs in the so-called stop-band. However, the structural response is still significantly large in the pass-band. In this paper, we combine PCs and acoustic … WitrynaTailoring of locally resonant sonic crystals to generate band gaps that prevent propagation of sound is ideally suited for difficult-to-address low frequency noise …
