An investigation into the combination of passive acoustic treatments and active structural acoustic control
An investigation into the combination of passive acoustic treatments and active structural acoustic control
This paper addresses the challenge of enhancing acoustic performance in scenarios where traditional methods may be inadequate, necessitating the combination of passive acoustic treatments and active control. The challenge here arises in finding an optimal combination of the passive and active treatments, particularlyfor situations where error sensing within a confined space is challenging, and passive treatments alone are insufficient. The proposed solution investigated here integrates a porous material and a Micro-Perforated Panel (MPP) with Active Structural Acoustic Control (ASAC) in a panel configuration, considering environmental acoustic needs and spatial constraints. The proposed system uses wave-based active absorption control and is investigated via a simulation-based study in this paper. Through a systematic assessment and comparison of various combinations of passive and active control methods, this research explores the interplay between porous materials, MPPs, and ASAC.

Abstract
This paper addresses the challenge of enhancing acoustic performance in scenarios where traditional methods may be inadequate, necessitating the combination of passive acoustic treatments and active control. The challenge here arises in finding an optimal combination of the passive and active treatments, particularlyfor situations where error sensing within a confined space is challenging, and passive treatments alone are insufficient. The proposed solution investigated here integrates a porous material and a Micro-Perforated Panel (MPP) with Active Structural Acoustic Control (ASAC) in a panel configuration, considering environmental acoustic needs and spatial constraints. The proposed system uses wave-based active absorption control and is investigated via a simulation-based study in this paper. Through a systematic assessment and comparison of various combinations of passive and active control methods, this research explores the interplay between porous materials, MPPs, and ASAC.
