• openAccess   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 ...
    • openAccess   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, ...
