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 ...

Air Absorption Error in Room Acoustical Modeling [PDF]
The Journal of the Acoustical Society of America, 2008 Most statistical and ray-tracing computer models take into account the absorption of sound by air when calculating the reverberation time. Extensive research by many scientist lead to the standardized calculation model for pure tone air absorption.
