Abstract

Wave Field Synthesis (WFS) is a technique that enables true spatial
reproduction over a large audience area with no dependence on the
listener position. During the last decade, some major advances have been
achieved for extending its use in every day applications. WFS can be
applied in high powered applications, such as sound reinforcement events,
in which true spatial audio would be needed. At present, dynamic midrange
loudspeakers, that form the arrays needed to recreate the secondary sound
sources cannot deliver such power because of its size. In this paper,
large drivers arrays are proposed to achieve high pressure fields that
fulfill the requirements of high power applications. Size and distance
between loudspeakers are chosen not to elevate the typical aliasing
frequencies and directivity of the standard arrays. To prove the benefits
of this arrays, some simulations of the reproduced sound field are
presented, together with acoustic measurements of an array of
loudspeakers.
