Analysis of sound absorption by a three-layer resonant and absorbing structure
The paper presents an analogous method of calculating resonance frequencies of a three-layer perforated structure. It was found that a model of vibrations with three degrees of freedom can be applied here. The possibility of widening frequency bands by using absorbing layers was developed and invest...
