Recent research showed that a loudspeaker connected with a shunt circuit can provide good sound absorption performance with a subwavelength thickness as the acoustic metamaterials. In this paper, the sound attenuation in a duct with such a shunted loudspeaker is investigated. Numerical simulations demonstrate that when the diaphragm of a shunted loudspeaker serves as a soft boundary, it can reduce the sound at low frequency. Moreover, the location of the shunted loudspeaker is also studied when the end of the tube is rigid.
