Specific Satisfaction and Usefulness—Snippets (RQ1.3)
EMA
Satisfaction with the snippets as measured by the six review indicators was considered sufficient (median scores of 3.5 or 4 of 5). The median snippet usefulness review indicator score was 4. In contrast, usefulness was rated less positive on the EMA evaluation survey question: about one-third of the snippets were not found useful at all (35%). However, the EMA survey asked about the direct helpfulness of the offered information/tips to the particular listening situation, whereas the snippet review score indicated a more general usefulness of the snippet. In line with this, the snippets that were acoustically tailored to the listening situation were rated somewhat more useful on the EMA survey question (at least a bit useful: 71%) than the nonacoustically tailored snippets (at least a bit useful: 49%). Although it was explained in the app’s introductory screens that not all offered snippets were linked to the entered listening situation, the mere fact that the snippets were offered directly after an entered listening situation may have given this impression nonetheless. Anecdotal evidence from the T3 questionnaire supported this: “The predefined connection between the snippets and listening situations was not always useful.” In turn, this may explain some of the suboptimal results found for both usefulness parameters. Lastly, it should be noted that both parameters were administered directly after viewing the snippets, whereas some information may have needed more time to sink in, or may have concerned an unconscious process.
