摘要

The concept of wave field synthesis (WFS) was introduced by Berkhout in 1988 [1]. It enables the generation of sound fields with natural temporal and spatial properties within a volume or area bounded by arrays of loudspeakers. Applications are found in real time performances as well as in reproduction of multitrack recordings. A logic next step was the formulation of a new wave field analysis (WFA) concept by Berkhout et al. in 1997 [2], where sound fields in enclosures are recorded with arrays of microphones and analyzed with postprocessing techniques commonly used in acoustical imaging. This way, both the temporal and spatial properties of the sound field can be investigated and understood. WFS and WFA meet in auralization applications: sound fields measured (or simulated) along arrays of microphone positions can be generated by arrays of loudspeakers for perceptual evaluation. Array technology was a core issue in the successful IST 5th framework project CARROUSO [3], which strongly contributed to worldwide knowledge and application of the concept.
