Abstract

In order to broaden the sound absorption bandwidth of single-leaf microperforated panel(MPP),The structure of MPP with partitioned cavity is introduced and its sound absorption performance is studied by impedance tube experiment. Results show that the MPP with partitioned cavity has two sound absorption peaks. Meanwhile, the sound absorption bandwidth is broaden and the sound absorption performance of the low and middle frequency is improved.
