Abstract:

© 2017 Institute of Noise Control Engineering. All rights reserved. Previous work has demonstrated that virtual sound barriers consisting of secondary sources and error microphones can effectively reduce sound radiation from a cavity opening. When secondary sources are implemented over the entire opening, the virtual sound barrier system can reduce sound radiation at any frequency if there are sufficient of them. An alternative secondary source arrangement is proposed in this paper by placing secondary sources at two different layers surrounding the edge of the opening. The simulation results show that there exists an upper limit effective frequency for the arrangement, which it is related to the size of the opening. With no secondary sources in the pathway of the opening, such a virtual sound barrier system is beneficial to the ventilation, lighting and access through the opening.
