扬声器阵列通常用于专业扩声系统，以提供对收听区域的均匀声音覆盖。它们还可用于将声音聚焦到用户进行半私密通信，并减少整体噪声污染。在这篇文章中，我们描述了一种用于扬声器阵列的宽带波束形成器的设计过程，它对扬声器的制造公差是稳健的，而制造公差是实现高指向性的限制因素。通过仿真和实际扬声器阵列的测量对所设计的波束形成器进行了评估。
Loudspeaker arrays usually are used in professional sound reinforcement systems to provide uniform sound coverage of the listening area. They can also be used for focusing the sound to the user for semi-private communication and reducing the overall noise pollution. In this paper we describe a procedure for designing broadband beamformers for loudspeaker arrays that is robust to the manufacturing tolerances of the loudspeakers - the limiting factor for achieving high directivity. The designed beamformer is evaluated using simulations and measurements of actual loudspeaker array.
