Coupling Helmholtz resonators for sound manipulation
SABAT, ROBINE; Leveque, Gaëtan; pennec, yan; Torrent, Daniel; Djafari Rouhani, Bahram IEEE (2021-09-20)In this work, we discuss the interaction between Helmholtz resonators, using the finite element method. We show that the coupling between two spheres gives rise to two resonant modes at low frequencies. One is symmetric ... -
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, ...
