Acoustic seminar | 25 December 2024

Periodic acoustic structures, particularly those incorporating Helmholtz resonators, have emerged as powerful tools for noise control and wave manipulation. This work will explore the innovative use of periodic networks of resonators as efficient noise filters, focusing on Helmholtz resonators and structures with intentional defects. By leveraging phenomena such as acoustic band gaps and the interaction of localized defect modes, these structures can achieve significant noise reduction and precise wave filtering. Key applications include enhancing acoustic waveguiding. The presentation will highlight findings from our recent studies, including the development of dual Helmholtz resonators for noise filtering and defective structures. Practical insights into designing such systems and their implications for modern acoustics will also be discussed.
