Floquet Topological Insulators for Sound [PDF]
, 2015 The unique conduction properties of condensed matter systems with topological order have recently inspired a quest for similar effects in classical wave phenomena. Acoustic topological insulators, in particular, hold the promise to revolutionize our ability to control sound, allowing for large isolation in the bulk and broadband one-way transport on ...

Investigation On The Role of Cavity and Slit of Cavity Resonators to Sound Absorption Behavior [PDF]
, 2011 Slit resonator and also perforated resonator are few kind of room interior finishing. They act as sound absorbers. Gen-erally, they are constructed of at least three basic types of absorbers, such as porous, membrane and cavity compo-nents.These types of

Theory of amplification of sound (acoustic phonons) by absorption of laser radiation in quantum wires with parabolic potential [PDF]
arXiv, 2002 Based on the quantum transport equation for the electron-phonon system, the absorption coefficient of sound (acoustic phonons) by absorption of a laser radiation in quantum wires with parabolic potential is calculated for the case of monophoton absorption and the case of multiphoton absorption.

Room dimensions and absorption inference from room transfer function via machine learning [PDF]
arXiv, 2023 The inference of the absorption configuration of an existing room solely using acoustic signals can be challenging. This research presents two methods for estimating the room dimensions and frequency-dependent absorption coefficients using room transfer functions.
