  • Patent number: 10810988
    Abstract: An acoustic panel for attenuating sound, and a system and method for making the acoustic panel. The acoustic panel employs rounded particles which are introduced into the cells of a core and fixed at a particular depth to form a septum layer providing substantially linear acoustic resistance to sound waves entering the cell. The particles may be between 100 microns and 700 microns in diameter, may be solid or hollow, may have smooth or textured surfaces, and/or may be made of syntactic foam or glass or ceramic. The system includes a positioning mechanism for positioning the particles at the particular depth, metering and gating mechanisms for introducing a metered amount of the particles into each cell, and a vibratory base for vibrating the particles to better pack them. Once the particles are in the cells, the septum layer is fixed, and the positioning mechanism is removed.
