Paper: A Virtual Endfire Loudspeaker Array for the Generation of Sound Beams

The paper A Virtual Endfire Loudspeaker Array for the Generation of Sound Beams presented by Sascha Spors and Hagen Wiersorf at the AIA-DAGA Conference on Acoustics considers the synthesis of sound fields that are limited to a linear region in space. Loudspeaker arrays used in endfire configuration are known to produce good results in this context. In this paper the use of a virtual endfire array is considered, which itself is synthesized by a broadside loudspeaker array using focused sources in Wave Field Synthesis.

The presentation slides as well as the MATLAB/Octave script to generate the figures are available. The script requires to download the Sound Field Synthesis toolbox.
