Our auditory environment is populated of sound sources: the goal of
perception is to extract their properties on the basis of the acoustical
signal reaching our ears. Which are the source properties relevant to the
listener? Upon which acoustical features is source perception based?
These issues have been investigated focusing on impact sounds, using
different experimental tasks: material identification, hardness scaling, and
dissimilarity rating. Despite differences in the tasks, and in the
investigated sound sets, strong regularities emerged, highlighting
a limited number of salient source properties, and acoustical features.
