A silencer duct 102, 202 that may be part of, for example, a turbomachine inlet may include a duct body 104, 204. A first perforated wall 110, 210 extends within the duct body 104, 204 and substantially parallel to an interior surface 112, 212 of the duct body 104, 204. A first acoustic absorbing material may be positioned between the duct body 104, 204 and the first perforated wall 110, 210. A silencer element 130, 230 may extend axially through the duct body 104, 204, the silencer element 130, 230 including a second perforated wall 140, 240 having a second acoustic absorbing material 120, 150, 220, 250 adjacent thereto. |
