本研究的目的是检查是否有可能直接恢复的大小的一个对象从声音的影响。具体来说，该研究旨在调查当球落在不同直径的盘子上时（实验1，2和3中分别为一个，两个或三个盘子），听众是否可以从声音中分辨出球的大小。在这个范例中，产生的大部分声音是来自盘子而不是球。听众既没有被告知使用了多少不同的球或盘子，也没有被告知球和盘子的材料。虽然听众提供了合理的球大小估计，他们的判断受到盘子大小的影响：当球落在更大的盘子上时，球被判断为更大。此外，听众一般无法识别球和板材料或板的数量在实验2和3中使用。最后，声音的各种声学特性与听者的判断相关。
The aim of this study is to examine whether it is possible to recover directly the size of an object from the sound of an impact. Specifically, the study is designed to investigate whether listeners can tell the size of a ball from the sound when it is dropped on plates of different diameters (on one, two, or three plates in Experiments 1, 2, and 3, respectively). In this paradigm, most of the sound produced is from the plate rather than the ball. Listeners were told neither how many different balls or plates were used nor the materials of the balls and plates. Although listeners provided reasonable ball size estimates, their judgments were influenced by the size of the plate: Balls were judged to be larger when dropped on larger plates. Moreover, listeners were generally unable to recognize either ball and plate materials or the number of plates used in Experiments 2 and 3. Finally, various acoustic properties of the sounds are shown to be correlated with listeners' judgments.
