“[Inventor Leon Scott] was interested in using the phonautograph [an early means of recording sound] generally to make sounds visible to the eye and specifically to create a form of automatic sound writing. This quest is something of an obsession in nineteenth-century science, and the phonautograph appeared in the middle of a much longer history. Certainly, one could argue that writing and musical notation are attempts to visualize sound that stretch back centuries. But these writing systems bear a largely arbitrary relation to the sounds that correspond to them. The same could be said for pictorial representations of sound.

Over the course of the nineteenth century there emerged another kind of visual representation of sound. To use the language of C.S Peirce, these were “indexical” images of sound, where the sound bears some kind of causal relation to the image itself (and, therefore, the image does not have a wholly arbitrary relation to the sound that conditioned it.) These images were artifacts of devices that could be affected by sound and thereby create images ordered in part by sonic phenomena. The use of these devices reflected an emergent interest in the scientific use of graphic demonstration and automatic inscription instruments, a practice that developed slowly in the last quarter of the eighteenth century and did not become prevalent until the nineteenth centure. Graphs, and later automatic recording devices, represented to their users a new kind of scientific “natural language”, where images would reveal relations hitherto unavailable to the senses. Attempts to represent sound visually were themselves artifacts of a larger process through which sound was isolated as a phenomenon and by means of which it would become an object of theoretical and practical knowledge in its own right. In fact, modern acoustics was very much shaped by this reliance on automatic imaging devices and the assumptions that this reliance embodied.
Attempts to visualize sound thus coincided with the construction of sound as an object of knowledge in its right: where speech, music, and other human sounds were reduced to special categories of noises that could be studied by the sciences of sound. In acoustics, frequencies and waves took precedence over any particular meaning that they might have in human life: “Frequencies remain[ed] frequencies regardless of their respective carrier medium.”

Visualizing sound as a species of vibration was a central task of the new science of acoustics. Visual sound had a symbiotic relation with quantification. Sound had, according to the accepted techniques of science, to be seen in order to be quantified, measured, and recorded; at the same time, some quantified and abstracted notion of sound had to be already in place for its visibility to have any scientific meaning. Again the product is an artifact of the process: visual sound required the simultaneous construction of sound as a discrete object of knowledge.
[…] Scott maintained a monomaniacal emphasis on writing as the aid to preservation and recall. It was because the phonautograph wrote that it would be able to preserve instantaneously and thus aid in recall. Scott sought to produce a “natural stenography” that would smash the distinction between orality and literacy because sound could literally write itself – hearing and speaking would become equivalent to reading and writing.”
