The aim of this expository chapter is to present the account of sound, tone and noise found in early phenomenology. After a short presentation of the views of Brentanians on the phenomenology of sound, in particular Carl Stumpf, the chapter focuses on Hedwig Conrad-Martius and Wilhelm Schapp. These authors defend the thesis that sounds, which they divide into tones and noises, present us with certain features of things that are also studied by physics, namely the materiality and the powers of things. They argue that these features are truly presented to us in sounds, that is, that we are acquainted with them, against the thesis that this would be a case of mere association. Conrad-Martius holds that the contrast between tones and noises depends on differences in the material composition of objects. Tones spring up from the object without hindrance while noises remain blocked in things and this is due to different arrangements between the parts of the objects; she argues that these arrangements are presented to us in our very experience of tone and noise. For Conrad-Martius, the way the materiality and powers of things are given to us in our sensory experience is in a qualitative continuity with what science says about them. This rejects the widespread philosophical thesis of a clash between our naïve and scientific worldviews.
