A parameter design method for multifrequency perfect sound-absorbing metasurface with critical coupled Helmholtz resonator
The low-frequency harmonic components of urban substation noise are easy to annoy the residents. Multi-frequency perfect sound-absorbing metasurface based on the Helmholtz resonator (HR) is an alternative solution to suppress the low-frequency harmonic noise. This paper proposes an efficient design...
