Systems and methods are provided for acoustic paneling. One embodiment is a method for fabricating an acoustic panel. The method includes receiving a sheet of thermoplastic paper, stamping/conforming the sheet into rows that each comprise a three dimensional shape, and transforming the sheet into a multi-celled core. Transforming the sheet includes identifying fold lines separating the rows, folding the sheet at the fold lines in a pleat fold, thereby uniting upper surfaces of adjacent rows and uniting lower surfaces of adjacent rows; and compressing the rows of the folded sheet together in the presence of heat, causing adjacent rows to fuse together into cells. The method further includes applying a backing sheet to the core, and applying a facesheet to a surface of the core that includes openings which direct a portion of airflow across the facesheet into the cells, resulting in acoustic control.
