The effects of various parameter combinations in parameter-mapping sonifications

This study will be investigating the design of parametermapping sonifications and investigating how different combinations of sound parameter mappings affect the user’s ability to understand and interpret sEMG data. The parameter mappings being used are all redundantly mapped and the specific parameter combinations are 1) pitch and loudness, 2) pitch, loudness, and attack time, and 3) loudness and attack time. There will be both spatialized (right and left) and nonspatialized versions of each of these mappings. These mappings will be used to present sonifications of two channels of sEMG data to participants to explore if they can identify muscle activation order (which muscle activates first) and relative muscle exertion levels (which muscle has a higher exertion). It is expected that participants will perform better with the spatialized mappings. It is also expected that the participants will perform better with the mappings that include attack time because this results in greater timbral variety.
