Manipulation of sonic waves by a quadruple set of Helmholtz resonators

Résumé

This paper examines the coupling effect between Helmholtz resonators (HRs) on mitigating low-frequency sound, using the finite element model. Previously, we highlighted the physical mechanism behind double coupled HRs, generating two resonance modes, symmetric and antisymmetric. Such coupling features can be increased by including four HRs, each containing four openings. This paper aims to simulate quadruple HRs which result in a significant degeneracy-lifting of the resonances providing new opportunities for sound monitoring, and controlled by the alteration of units’ separation.
