초록

A duct liner assembly includes a noise attenuation layer for absorbing noise energy that is covered by a face sheet. The face sheet includes a seam that is covered by an acoustically active splice. The acoustically active splice includes a plurality of acoustic regions that provide for communication of noise energy to the noise attenuation layer to minimize creation of acoustically dead areas.

청구항

What is claimed is: 1. A liner assembly for a duct comprising: a noise attenuation layer; a face sheet over said noise attenuation layer, said face sheet including a plurality of openings and a seam; and a splice for covering said seam, wherein said splice includes an acoustic region open to said plurality of openings within said face sheet, wherein said acoustic region comprises an open area defined by surrounding portions of said splice. 2. The assembly as recited in claim 1, wherein said splice includes a center portion covering said seam and said...
