This study includes the first work about the absorption of a panel absorber under the effects of microperforation, air pumping, and linear and nonlinear vibrations.
In practice, thin perforated panel absorber is backed by a flexible wall to enhance the acoustic performance within the room.
The panel is easily excited to vibrate nonlinearly and the wall can vibrate linearly.
However, the assumptions of linear panel vibration and no wall vibration are adopted in many research works.
The development of the absorption formula is based on the classical approach and the electroacoustic analogy, in which the impedances of microperforation, air pumping, and linear and nonlinear vibrations are in parallel and connected to that of the air cavity in series.
Unlike those finite element, numerical integration, and multiscale solution methods and so forth, the analytic formula to calculate the absorption of a panel absorber does not require heavy computation effort and is suitable for engineering calculation purpose.
The theoretical result obtained from the proposed method shows reasonable agreement with that from a previous numerical integration method.
It can be concluded that the overall absorption bandwidth of a panel absorber with an appropriate configuration can be optimized and widened by making use of the positive effects of microperforation, air pumping, and panel vibration.
