An acoustic panel for sound attenuation employs a septumized cellular core sandwiched between a backsheet and a linear acoustic facesheet. The linear acoustic facesheet employs a linear material layer that impedes acoustic waves entering the core substantially linearly over a wide range of frequencies and sound of pressure levels.
