Reconfigurable sound anomalous absorptions in transparent waveguide with modularized multi-order Helmholtz resonator
Helmholtz resonators offer an ideal platform for advanced sound absorbers, but their utility has been impeded by inherent frequency range limitations and the lack of function reconfiguration. Here, we introduce a multi-order Helmholtz resonator (MHR) that allows multiple monopolar resonant modes the...
