在本文中，我们介绍了一种新开发的声场再现和共享系统。该系统由一个 80 通道富勒烯形状麦克风阵列和一个 96 通道扬声器阵列组成，安装在一个称为“音桶”的外壳中，因其形状而得名。木桶有两个功能。首先，它充当精确的声场再现系统。从任意声场的麦克风阵列采集到的声音信号，经过基于边界面控制原理修改幅度和相位的滤波器后，可以在音桶中再现。大量扬声器确保了声像的精确方向和深度。其次，它作为声场共享系统的平台。对于木桶内的受试者来说，位于远处的几个木桶似乎存在于同一声场中。此外，木桶足够大，可以在里面演奏乐器。在对原始声场的脉冲响应进行卷积之后，对象产生的音乐声音或声音可以由远处木桶中的对象共享。详细解释了该系统的概念。
In this paper, we introduce a newly developed sound-field-reproducing and -sharing system. The system consists of an 80-channel fullerene-shaped microphone array and a 96-channel loudspeaker array mounted in an enclosure called a sound cask, so named because of its shape. The cask has two functions. First, it functions as a precise sound field reproduction system. The sound signals acquired from a microphone array in any sound field can be reproduced in the sound cask after passing through filters that modify the amplitude and phase on the basis of the boundary surface control principle. The large number of loudspeakers result in the precise orientation and depth of sound images. Second, it functions as a platform for a sound-field-sharing system. Several casks located remotely can appear to exist in the same sound field for subjects inside a cask. In addition, the cask is large enough for one to be able to play a musical instrument inside it. The musical sound or voices produced by subjects can be shared by subjects in a distant cask after convoluting the impulse responses of the original sound field. The concept of the system is explained in detail.
