Tunable active sound absorbers

   
   

The sound absorber is a combination of an acoustical transformer with an actively simulated acoustical impedance. The acoustical transformer transforms the high active impedance into a low impedance at the mouth of the transformer. The absorber is tuned by changing the active impedance.

El amortiguador sano es una combinación de un transformador acústico con una impedancia acústica activamente simulada. El transformador acústico transforma la alta impedancia activa en una impedancia baja en la boca del transformador. El amortiguador es templado cambiando la impedancia activa.
