Ultrabroadband sound control with deep-subwavelength plasmacoustic metalayers
Nature Communications, 2023 Controlling audible sound requires inherently broadband and subwavelength acoustic solutions, which are to date, crucially missing. This includes current noise absorption methods, such as porous materials or acoustic resonators, which are typically ...

Acoustic Coatings—A Discreet Way to Control Acoustic Environment
Frontiers in Built Environment, 2021 Acoustic comfort is directly related to enhanced well-being and performance of people. A typical challenge faced by architects and acousticians is to achieve adequate acoustics while maintaining the aesthetics of the space and reducing the visual aspects

Study of Low-Frequency Sound Absorption Based on Negative Stiffness Membrane Structure
Symmetry, 2022 The system stiffness of a negative stiffness membrane structure is widely investigated in metamaterial research, and some special performances have been achieved. While for acoustics, low-frequency absorption still remains a big issue, so in this work, a

Acoustic Absorption and Dynamic Viscosity in Polymers [PDF]
The Journal of the Acoustical Society of America, 1966 We have obtained results that show that acoustic absorption in linear polysiloxanes varies with viscosity and frequency in a unique manner. At any constant temperature, a significant relaxation is found, with a broad spectrum of relaxation frequencies.
