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…

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…
