Spatial sound and sound localization on a horizontal surface for use with interactive surface (tabletop) computers
… tabletop computers?" "How does our perception of spatial sound change with these different loudspeaker configurations?" and "What panning methods should be used to maximally use the spatial localization abilities of the user(s)?" Using a custom-built tabletop computer setup, the work presented in …

Theory and Design of Spatial Active Noise Control Systems
The concept of spatial active noise control is to use a number of loudspeakers to generate anti-noise sound waves, which would cancel the undesired acoustic noise over a spatial region. The acoustic noise hazards that exist in a variety of situations provide many potential applications for spatial …
