摘要：
Methods and apparatuses for representing a sound field in a physical space are provided and described as embodied in a system that includes a sound transducer array along with a touch surface-enabled display table. The array may include a group of transducers (multiple speakers and/or microphones). The array may be configured to perform spatial processing of signals for the group of transducers so that sound rendering (in configurations where the array includes multiple speakers), or sound pick-up (in configurations where the array includes multiple microphones), may have spatial patterns (or sound projection patterns) that are focused in certain directions while reducing disturbances from other directions.
摘要（中）：
用于在物理空间中表示声场的方法和装置被提供和描述为具有包括具有触摸表面的显示表的声音换能器阵列的系统。 阵列可以包括一组换能器（多个扬声器和/或麦克风）。 该阵列可以被配置为执行用于该组换能器的信号的空间处理，使得声音渲染（在阵列包括多个扬声器的配置）或声音拾取（在阵列包括多个麦克风的配置中）可以具有空间 在某些方向上聚焦的图案（或声音投影图案），同时减少来自其他方向的干扰。
