In this manuscript both the mechanics and the§perception of the §sounds from rolling §and bouncing objects were studied. The§characteristics of the §interactions between balls and plates are defined by§physical §properties of the components in the interaction,§among them the §size and speed of the rolling balls, and, perhaps,§the thickness of §the plate over which the ball rolls. The research§question was to §determine to what extent a listener could "hear"§these physical §properties. By calculating the psychometric function§for the §participants estimations, an exact measure of the§probability that a §listener could correctly identify the difference in§one of the physical §parameters was calculated. What kind of information§in the sound §the listeners based their decisions upon was also§investigated. The §influence and relative weighting of different sources§of information §was studied in perception experiments. Further§arguments are §provided that show the auditory perception of§mechanical object §properties is a layered process, and detection and§estimation find §place at a different level of such a layered process.
