In-parallel resonators to increase the absorption of subwavelength acoustic absorbers in the mid-frequency range
The acoustic effects of in-parallel resonators is compared to the behavior of a classical single degree of freedom resonator for which the resistance and the mass are in series. In-parallel resonators serve to enhance the acoustic absorption for mid-frequencies thereby extending the active frequency...
