Matryoshka Sonic Crystals for Advanced Noise Control

Research Overview:
Exploring the design and optimization of Matryoshka sonic crystals to enhance sound attenuation.
This research focuses on the development of Matryoshka sonic crystals—a type of acoustic metamaterial designed to control noise by trapping and attenuating sound waves. By experimenting with different scatterer shapes, periodicity patterns, and material compositions, we aim to improve noise reduction in urban environments, industrial settings, and transportation systems.

• Key Techniques: Acoustic simulations, experimental validation, optimization of geometric structures using machine learning technique.

• Potential Applications: Noise barriers for highways, industrial machinery noise control, and quiet urban zones.

Effect of Scatterer Shape, Opening Angle, and Periodicity on Sound Attenuation by Local Resonating Sonic Crystals

This research was presented at the prestigious Internoise 2024 conference, where it explored how the shape, opening angle, and periodicity of scatterers in sonic crystals impact sound attenuation. The study investigates innovative designs in local resonating sonic crystals to enhance noise control in various applications, including transportation and urban noise mitigation.

• Key Techniques: Acoustic simulations, empirical testing, periodicity optimization.

• Key Findings: Results showed a significant improvement in sound attenuation by altering scatterer geometry, periodicity and configuration. This contributes to a more efficient design of noise control solutions, offering practical applications for both industrial and urban environments.
