Vision has been the primary focus of naturalistic philosophical research concerning perception and perceptual experience. Guided by visual experience and vision science, many philosophers have focused upon theoretical issues dealing with the perception of objects. Recently, however, hearing researchers have discussed auditory objects. I present the case for object perception in vision, and argue that an analog of object perception occurs in auditory perception. I propose a notion of an auditory object that is stronger than just that of an intentional object of audition, but that does not identify auditory objects with the ordinary material objects we see.

Frequently, we learn of the locations of things and events in our environment by means of hearing. Hearing, I argue, is a locational mode of perceiving with a robustly spatial phenomenology. I defend three proposals. First, audition furnishes one with information about the locations of things and happenings in one’s environment because auditory experience itself has spatial content—auditory experience involves awareness of space. Second, we hear the locations of things and events by or in hearing the locations of their sounds. Third, we auditorily experience sounds themselves as having relatively stable distal locations. I reject skepticism about spatial audition and auditory experience tracing to Strawson’s Individuals , and suggest that spatial auditory experience grounds a form of perceptual access to objects and events that is critical to negotiating one’s environment.

Hearing and auditory perception are rapidly developing topics in the philosophy of perception. Recent work has focused on characterizing what we hear and on similarities and differences between audition and other modalities. Future work should address how theorizing about audition impacts theorizing about perception more generally. This entry concerns questions about the objects and contents of hearing. It includes discussion of the spatial content of audition, of the role of time and pitch in the individuation of auditory objects, and of audition's role in the perception of speech.

Sounds and Perception brings together original essays on auditory perception and the nature of sounds - an emerging area of interest in the philosophy of mind and perception, and in the metaphysics of sensible qualities. The essays discuss a wide range of issues, including the nature of sound, the spatial aspects of auditory experience, hearing silence, musical experience, and the perception of speech; a substantial introduction by the editors serves to contextualise the essays and make connections between them. The collection serves both as an introduction to the nature of auditory perception and as the definitive resource for coverage of the main questions that constitute the philosophy of sounds and audition.

It is tempting to hold that perceptual experience amounts to a co-conscious collection of visual, auditory, tactual, gustatory, and olfactory episodes. If so, each aspect of perceptual experience on each occasion is associated with a specific modality. This paper, however, concerns a core variety of multimodal perceptual experience. It argues that there is perceptually apparent intermodal feature binding. I present the case for this claim, explain its consequences for theorizing about perceptual experience, and defend it against objections. I maintain that just as one thing may perceptually appear at once to jointly bear several features associated with the same sense modality, one thing also may perceptually appear at once to jointly bear features associated with different sense modalities. For instance, just as something may visually appear at once to be both red and round, or to have a red part and a green part, something may multimodally perceptually appear at once to be both bright and loud, or to have a red part and a rough part. The main lesson, I argue, is that perceiving is not just co-consciously seeing, hearing, feeling, tasting, and smelling at the same time. And perceptual phenomenal character is not on each occasion exhausted by that which is distinctive to or associated with a given modality, along with that which accrues thanks to simple co-consciousness. Not all ways of perceiving are modality specific. I defend this account against three main objections: that singular content theorists avoid my conclusions; that apparent infusion of perceptible features is required for perceptually apparent binding but does not occur intermodally; and that the diversity of objects across modalities makes perceptually apparent intermodal binding rare.

Is speech special? This paper evaluates the evidence that speech perception is distinctive when compared with non-linguistic auditory perception. It addresses the phenomenology, contents, objects, and mechanisms involved in the perception of spoken language. According to the account it proposes, the capacity to perceive speech in a manner that enables understanding is an acquired perceptual skill. It involves learning to hear language-specific types of ethologically significant sounds. According to this account, the contents of perceptual experience when listening to familiar speech are of a variety that is distinctive to hearing spoken utterances. However, perceiving speech involves neither novel perceptual objects nor a unique perceptual modality. Much of what makes speech special stems from our interest in it.
