Sound insulation properties of a spherical structure of subwavelength size
AIP Advances, 2019 Because of the limited sound insulation provided by a single material, it is common to use multiple layers of materials to improve the effects of sound insulation, but multiple materials increase the size of the model.

Sound insulation at low frequencies [PDF]
The Journal of the Acoustical Society of America, 1972 The transmission of airborne sound between two rooms coupled by a panel is investigated. At low frequencies individual modes in the rooms and the panel control the transmission. It is shown that resonant modes in the room are the chief cause of frequency-dependent variations in low-frequency sound insulation.

Full‐Field Damage Monitoring in Architected Lattices Using In situ Electrical Impedance Tomography
Advanced Functional Materials, EarlyView.In situ electrical impedance tomography (EIT) turns 3D‐printed, CNT‐infused architected lattices into full‐field damage‐imaging systems. Tunable Voronoi‐based geometries act as active sensing architectures, enabling conductivity maps to detect early‐stage damage and localise sequential ligament fracture before catastrophic failure.
