Single and coupled Helmholtz resonators for low frequency sound manipulation
SABAT, ROBINE; pennec, yan; Lévêque, Gaëtan; Torrent, Daniel; Ding, Changlin; Djafari Rouhani, Bahram American Institute of Physics (2022-08-12)In this work, we use the finite element method to study the acoustic properties of single and coupled Helmholtz resonators (HRs). Each HR consists of a sphere drilled with one or several small openings. For a single HR, ...
