Figure 1.
The classification was elaborated through a brainstorming using affinity diagrams.
Each low-level dimension was written on a post-it note. The notes were then moved to form clusters based on their degree of similarity, constituting the intermediate-level dimensions used to reference mappings in this systematic review for both physical and auditory domains.

Table 7.
High-level trends in the distribution of mapping occurrences.
Figure 2.
Proportions of mapping occurrences normalized against high-level categories in the physical domain.
It can be observed that Loudness-related auditory dimensions are used mainly to sonify physical quantities belonging to the high-level category Kinetics. Spatial auditory dimensions are used mainly to sonify physical quantities belonging to the high-level category Kinematics.
