 However, the individuals to which audible attributes are perceptually attributed need not be identical with ordinary objects or events. Instead, audible attributes may belong in the first instance to sounds. Sounds plausibly are distinct from ordinary or extra-acoustic individuals (O’Callaghan 2007, 2011). Suppose then that one could not hear an ordinary object or event without there existing an audible sound, as well as that sounds can mislead about their sources (it might sound like drumming but be hammering).
