AbstractPhononic crystals (PCs) have the ability to have phononic bandgaps dependent on the acoustic properties of its constituent materials (i.e., mass, elasticity). Forming a 1D periodic variation using a viscoelastic material allow the PC to have more wave vibration attenuation in the longitudinal direction. In this study, the low transmission zones and the vibration attenuation properties of a one-dimensional PC subjected to flexural vibration was evaluated experimentally. Results were presented in the form of frequency response functions and showed the flexural low-frequency zones starting at 500 Hz with three zones in the 16kHz range.
