 One might object by resisting the phenomenological claim that we experience sounds as distally located, for instance by suggesting that audition is aspatial, or that audition is spatial but sound sources rather than sounds are auditorily localized (see section  3.1 Spatial Hearing  for further discussion). Or, one might accept some measure of illusion. Another possibility is that we experience only a small subset of the locations sounds occupy during their lifetimes (for instance, while at their sources), and simply fail to experience where they are at other times. This avoids ascribing illusion. Finally, Fowler (2013) argues indirectly on the basis of echoes against distal theories of sound.
