Natural sonic crystal absorber constituted of seagrass (Posidonia Oceanica) fibrous spheres

Abstract We present a 3-dimensional fully natural sonic crystal composed of spherical aggregates of fibers (called Aegagropilae) resulting from the decomposition of Posidonia Oceanica. The fiber network is first acoustically characterized, providing insights on this natural fiber entanglement due to...
