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...

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...

In this article we will study sound—specifically, how sound allows us to communicate in a classroom and can improve that communication. You learn is measured people called acoustics engineers help architects designers make sure classrooms are not too noisy—or quiet. We even have some experiments you do measure sounds at home, school, or football stadium.
