本文详细介绍了实验验证的数值预测的有源强度使用一个盒子形的声辐射器。散热器的顶部和底部是薄钢板，由电磁振动器以其结构模式之一驱动。顶板的四个角被移除，以容纳代表活动源的带挡板的扬声器。为了提供实验的精确控制，振动器和扬声器的驱动信号由控制计算机产生和监控
This paper details the experimental verification of the numerically predicted active source strengths using a box shaped acoustic radiator. The top and bottom of the radiator were thin steel plates which were driven in one of their structural modes by an electromagnetic shaker. The four corners of the top plate were removed to accommodate baffled loudspeakers, representing the active sources. To provide precise control of the experiment, the driving signals to the shakers and loudspeakers were generated and monitored by a control computer
