摘要

In this article, a combined analytical and experimental study conducted on the feasibility of implementing a relaxed zero spillover control (RZSC) scheme for active structural acoustic control (ASAC) is presented. The aim of this effort is to actively control sound fields inside a three-dimensional rectangular enclosure into which noise is transmitted through a flexible boundary. Piezoceramic patches, which are mounted on the flexible boundary, are used as actuators, and microphones, which are placed inside and outside the enclosure, are used as sensors. In the experiments, an attenuation of 5.56 dB is obtained for broadband excitation in the frequency range of 20 Hz ≤ f ≤ 220 Hz.
