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(More)
Wave Field Synthesis (WFS) enables correct spatial reproduction of acoustic events for larger groups of people. Such events often include acoustic information of the recording space which is then “auralized” after convolution with the sound sources. The acoustic information is acquired by measuring impulse responses. Spatial information is(More)
It is commonly accepted that the sound reflections from real physical objects are much more complicated than what usually is and can be modelled by room acoustics modelling software. The main reason for this limitation is the level of detail inherent in the physical object in terms of its geometrical and acoustic properties. In the present paper, the(More)
Wave field synthesis (WFS) enables the accurate reproduction of a sound field for a large listening area with correct characteristics for each listener position. An exact perspective on the synthesized wave field is provided for every listener. Therefore, WFS-technology is ideally suited to be combined with augmented reality systems, where every user(More)
The state of the art of wave field synthesis (WFS) systems is that they can reproduce sound sources and secondary (mirror image) sources with natural spaciousness in a horizontal plane, and thus perform satisfactory 2D auralization of an enclosed space, based on multitrace impulse response data measured or simulated along a 2D microphone array. However,(More)
Dominancy and high frequency on one side, as well as combinations of species on the other side, are important f rom sociological and ecological point o f view. Predominancy of a species can be looked upon as an expression of its success in the struggle for life. After all concurrence, habitat and priority of species determine the composition o f plant(More)
