 Auditory perception raises a variety of challenging philosophical questions. What do we hear? What are the objects of auditory awareness? What is the content of audition? Is hearing spatial? How does audition differ from vision and other sense modalities? How does the perception of sounds differ from that of colors and ordinary objects? This entry presents the main debates in this developing area and discusses promising avenues for future inquiry. It discusses the motivation for exploring non-visual modalities, how audition bears on theorizing about perception, and questions concerning the objects, contents, phenomenology, varieties, and bounds of auditory perception.
