For the improvement of absorption performance of absorbing material, the thickness of material should be increased or the material should have non-flat surface. In this study, the acoustic characteristics and acoustic absorption improvement method of double layered polyester absorbing material system was conducted. For this study, the theoretical model was established and this model was compared with the measured data for this system. Also, for the improvement of absorption performance, the installation method of this double layered system was suggested.
