Abstract:
A multi-sectional acoustic septum 'that includes sections which have different acoustic resistance properties. The multi-sectional acoustic septums extend vertically with the acoustic cell and are capable of increasing the effective acoustical length of the acoustic cell. The multiple acoustic properties provided by the multiple acoustic sections also make it possible to target specific frequency ranges within the overall frequency range of the acoustic cell.
