This research presents an application of the additive manufacturing (AM) technology for active acoustic absorption device. Fabrication of functional devices in acoustic system is one of the challenging goals of additive manufacturing technology. In order to achieve this objective, an important step is to test the acoustic performance and characteristics of AM device and make it active from an acoustics point of view. Numerous roadblocks that need to be overcome exist and research activities in this field are rare. Thus this research aims to experimentally observe and utilize the anisotropic absorption coefficients of AM device caused by its anisotropic stiffness characteristics. In addition, this research also proposes the concept of an active acoustic device. Some experiments are carried out to show the validity of the active acoustic device using AM technology.
