In 4 experiments, participants listened to suspended occluded objects set into vibration by a pendular hammer. In Experiment 1, participants provided analogue measures of the heights and widths of 3 rectangular steel plates equal in area and weight. The same report method and rectangular dimensions were used in Experiment 2 with 3 plates each of steel, wood, and Plexiglas. Heights and widths were distinguished and perceived in similar proportions to the actual dimensions regardless of material composition. In Experiments 3 and 4, participants successfully identified circular, triangular, and rectangular plates of a single material (Experiment 3) and of 3 different materials (Experiment 4). Discussion focuses on the dependency of perceived dimensions on the physical properties and linear dimensions of the plates and the acoustic structure determined by the solutions to the 2-dimensional wave equation.
在4个实验中，参与者聆听了由摆锤敲击而振动的悬浮堵塞物体发出的声音。在实验1中，参与者对3块面积和重量相等的矩形钢板的高度和宽度进行了类比测量。实验2使用了相同的报告方法和矩形尺寸，有3块钢板、3块木板和3块有机玻璃板。无论材料成分如何，高度和宽度都能被区分出来，并且与实际尺寸的比例相似。在实验3和实验4中，参与者成功识别了单一材料（实验3）和3种不同材料（实验4）的圆形、三角形和矩形板。讨论集中在感知尺寸对板材物理特性和线性尺寸的依赖性，以及由二维波动方程的解所确定的声学结构。
