Download or read book Active Structural Acoustic Control as an Approach to Acoustic Optimization of Lightweight Structures written by Dirk Mayer and published by . This book was released on 2001 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conventional approaches to optimizing the acoustic behavior of lightweight structures have mainly been restricted to the concept of Active Noise Control(ANC). This concept is aimed to attenuating primary noise sources with secondary controlled noise sources by taking advantage of destructive interference. However it is also possible to actively control the vibrating structure using piezoceramic actuators to alter very intensively sound-radiating operating deflection shapes. This approach is referred to as Active Structural Acoustic Control (ASAC). The applicability of this concept to real systems is demonstrated by means of a simple model with experimental measurement systems employed in the lower frequency range. This study focuses on the utilization of a modern measurement technology i.e. the Spatial Transformation of Sound Fields(STSF) which facilitates the determination of important parameters of the vibro-acoustic system at a time. The radiation efficiency is of major importance to the evaluation of the acoustic system behavior. As the lower frequency range is considered the dynamic system behavior is determined by means of the Experimental Modal Analysis (EMA). The results of this study show the radiation efficiency of the unregulated and of the actively controlled system.
