It is often supposed that our experience of sounds is as of things distinct from the material world of sight and touch: reflecting on the character of our auditory experience might seem to confirm that. This paper describes the features of our auditory experience that can lead one to think of sounds in this way. It then describes a way we can experience sounds as being part of the material world. Since this is a kind of experience that essentially involves more than one sense, the paper ends by drawing some conclusions about how we should think about the senses.
