Topological acoustics is an emerging field that lies at the intersection of condensed matter physics, mechanical structural design and engineering. It explores construction novel artificial structures, such as acoustic metamaterials phononic crystals, to manipulate sound waves robustly, taking advantage topological protection. Early work on was limited duplicating phases have been understood in...

Spatial acoustics constitute a major part of our experience of the world. The ability to make sense of our environment depends on spatial awareness and hearing plays a major role in this process. Yet in videogames, the acoustic information available to us is reduced. This cripples our hearing, leaving spatial awareness dependant on vision alone. This thesis examines the problems surrounding the...

Virtual audio reality environments have in recent years become popular in such fields as computer music, acoustics, multimedia, and telecommunications [1]. There are often computational constraints that lead to very simplified systems that faintly resemble the physical reality. We present a distributed expandable virtual audio reality system that can accurately yet efficiently model room acoust...

For architects, real-time 3D visual rendering of CAD-models is a valuable tool. The architect usually perceives the visual appearance of the building interior in a natural and realistic way during the design process. Unfortunately this only emphasizes the role of the visual appearance of a building, while the acoustics often remain disregarded. Controlling the room acoustics is not integrated i...

in parallel with the maintenance of a much larger inhouse research establishment than that which had existed before the war. Both the academic and Navy communities were motivated by the probability that the USSR would, as they did, initiate an energetic development of submarine capabilities built on technology and personnel drawn from Germany. The key scientist at this point was Carl Eckart, an...

Some high-resolution direction-of-arrival DOA estimation methods, such as the MUSIC method, have been developed based on vectorsensor array. However, these high-resolution methods suffer from serious drawbacks. Indeed, they are not able to estimate coherent signals and sensitive to calibration errors. Mainly to overcome these limitations and in particular to satisfy practical engineering applic...
