5.3 Differences between types of sound data
We analyzed game sessions in terms of the three types of sound data. There were significant differences in the follow-ing items.
Time spent on a session (p = 0.006). The multiple comparison test showed differences between music and the other two sound types (speech and mixed). The participants spent longer with the music. With the further investigation on the time spent on a session by each participant group, only NHL showed differences.
The number of actions of listening to the cur-rent solution (p < 0.001). The multiple comparison test revealed differences between the music and the other two sound types. Participants chose to listen to the current so-lution more often with the music than the other two types of sound. Only NHL showed differences in the number of actions for listening to the current sound. Table ?? shows the p-value and the mean value of each participant group for each sound type on the time spent in a session in seconds per game, and the number of listenings to the current sound per game.
The rate of sessions in which the equalization im-proved (p = 0.034). The multiple comparison test showed differences between speech and music. The mean ratios were 0.62, 0.83, and 0.77 for speech, music, and mixed, respec-tively.
