Abstract: A duct liner assembly includes a noise attenuation layer for absorbing noi se 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.
