Phononic glass: A robust acoustic-absorption material
The Journal of the Acoustical Society of America, 2012In order to achieve strong wide band acoustic absorption under high hydrostatic pressure, an interpenetrating network structure is introduced into the locally resonant phononic crystal to fabricate a type of phononic composite material called “phononic glass.” Underwater acoustic absorption coefficient measurements show that the material owns high ...

Acoustic absorption properties of materials
Construction and Building Materials, 1988Abstract The sound absorption characteristics of some 30 different but easily available sound absorbing materials have been studied previously. Presented here in brief are a selection of these materials, their description, methodology used and results obtained.

Observation of Coherent Perfect Acoustic Absorption at an Exceptional Point.
Physical Review LettersNon-Hermitian systems have recently shown new possibilities to manipulate wave scattering by exploiting loss, yet coherent perfect absorption at an exceptional point (CPA EP) remains elusive in acoustics.

Proceedings of the Institution of Mechanical Engineers, Part L: Journal of Materials: Design and Applications
Mechanical metamaterials have become increasingly attractive due to their numerous attributes, including low weight, high strength, negative Poisson's ratio, and high energy absorption. Traditionally, metamaterials have been utilised in wave manipulation

Nonresonant acoustic absorption of Ising magnet
Theoretical and Mathematical Physics, 1994Zubarev's nonequilibrium statistical operator method is used to construct a theory of the nonresonant acoustic absorption of the linear Ising magnet, the basic Hamiltonian of which is of the two-particle kind and is treated without approximations. The frequency dependence of the absorption is determined and found to differ analytically from the well ...

Sound Absorption Coefficients and Acoustic Impedance
The Journal of the Acoustical Society of America, 1941The relation between normal acoustic impedance and the various types of absorption coefficient has been discussed and specific formulas for the coefficients in terms of acoustic impedance have been published. Contours of constant absorption coefficient plotted as a function of the real and imaginary parts of acoustic impedance plotted on a linear scale

Smart materials and structures (Print)
Low-frequency broadband sound absorption is a hot topic in the field of acoustics. For the Helmholtz resonator, the low-frequency sound wave can be controlled by adjusting the size of the structure.
