Optimal Sound Absorbing Structures
Min Yang, Shuyu Chen, Caixing Fu +1
Causal nature of the acoustic response, for any materials or structures, dictates an inequality that relates the absorption spectrum of the sample to its thickness. We present a ge…
Sound Absorption by Subwavelength Membrane Structures: A Generalized Perspective
Min Yang, Yong Li, Chong Meng +4
Decorated membrane, comprising a thin layer of elastic film with small rigid platelets fixed on top, has been found to be an efficient absorber of low frequency sound. In this work…
Subwavelength total acoustic absorption with degenerate resonators
Min Yang, Chong Meng, Caixing Fu +3
We report the experimental realization of perfect sound absorption by sub-wavelength monopole and dipole resonators that exhibit degenerate resonant frequencies. This is achieved t…
Hybrid membrane resonators for multiple frequency asymmetric absorption and reflection in large waveguide
Caixing Fu, Xiaonan Zhang, Min Yang +2
We report that Hybrid membrane resonators (HMRs) made of a decorated membrane resonator backed by a shallow cavity can function as Helmholtz resonators (HRs) when mounted on the si…
