 Finally, the requirement of fidelity to auditory content may also be challenged by proposing a different phenomenology. For example, Kalderon (2017) argues that sound is an event that is identical to the propagation in every direction of a pattered disturbance by means of a medium, such as air or water (2017: 105). He claims, indeed, that auditory phenomenology is essentially emanative phenomenology. According to emanative phenomenology, we hear sound as an ever-expanding sphere which is the medium disturbance propagating in every direction from its source. Sound is like
