Adaptive Acoustic Structures: Concept,Realization and Applications

Yin Xuefei Chen Kean (College of Marine Engineering, Northwestern Polytechnical University Xi'an, 710072)  
Based on active control of noise and vibration and functional structure, adaptive acoustic structures have been developed in recent decade to effectively reduce low-frequency noise, which can be suitable for complicated acoustic environments. In this paper basic concept and main features are introduced firstly, and then several key approaches for constructing the active acoustic structure are examined, including error sensing strategy, selection of secondary sources and error sensors. Finally an example for engineering application is provided.
