Resonance absorbers with additional damping
Abstract
Simplified electrical equivalent circuit diagrams are developed from impedance measurements on porous layers in a measurement tube, and give a rough approximation to the impedance behavior of porous layers. The effect of these porous layers on the resonance absorber is calculated and compared with the measured results.
