Summary
The control and attenuation of low-frequency sound waves remain a longstanding challenge in many engineering fields. Because low-frequency acoustic waves have large wavelengths, conventional materials often require thick and heavy structures to achieve meaningful sound reduction. Developing lightweight and effective approaches for controlling low-frequency sound therefore remains an important scientific and technological challenge. This project explores a new class of acoustic materials that use microscopic bubbles trapped within carefully designed structures. When exposed to sound waves, thes
