Presents a unified framework of far-field and near-field array techniques for noise source
identification and sound field visualization, from theory to application. Acoustic Array …

A technical review is presented of the development of a special type of planar loudspeaker
array for wave field synthesis, known as multiactuator panel. It consists of a thin, stiff panel …

A surround sound system for reproducing a spatial sound field in a sound control region
within a room having at least one sound reflective surface. The system uses multiple …

Sound reproduction systems using open arrays of loudspeakers in rooms suffer from
degradations due to room reflections. These reflections can be reduced using pre …

Portions of this work were presented in “Wave field synthesis, adaptive wave field synthesis
and ambisonics using decentralized transformed control: Potential applications to sound …

Spatial sound reproduction systems aim to produce a desired sound field over a volume of
space. At high frequencies, the number of loudspeakers required is prohibitive. This paper …

This paper derives a superfast Toeplitz matrix inversion method using FFT techniques. The
approach casts the non-periodic Toeplitz matrix solution into a periodic framework and uses …

Sound reproduction systems using omnidirectional loudspeakers produce reflections from
room surfaces which interfere with the desired sound field within the array. While active …

Reproduction of a given sound field interior to a circular loudspeaker array without
producing an undesirable exterior sound field is an unsolved problem over a broadband of …

Wave field synthesis is a sound field reproduction technology which assumes that the
reproduction environment is anechoic. A real reproduction space thus reduces the objective …
