 In the above arguments an important role is played by the following requirement: A theory of sounds should be true to the phenomenological content of auditory perception. It seems quite reasonable to require that as sounds are the objects of hearing, whatever they are should be somewhat revealed in hearing. In point of fact, there are two ways in which the fidelity to auditory content requirement can enter the arguments. In a strong version (O’Callaghan 2009) it may be held that no theory of sounds “should make the fact of location perception a wholesale illusion” (2009: 29); hence, as sounds are represented as located, it would follow that they are correctly so represented. It may be argued that this principle is too strong because it is unjustifiably specific. Why should location, among all possible features of sounds, be protected against the possibility of systematic illusion?
