Arousing the sound: a field study on the emotional impact on children of arousing sound design and 3D audio spatialization in an audio story

Description

Sound from media increases the immersion of the audience in the story, adding credibilityto the narration but also generating emotions in the spectator. A study on children aged9–13 years (N=253), using an audio story, investigated the emotional impact of arousalvs. neutral treatment of sound and 3D vs. stereo mix spatialization. The emotional impactwas measured combining three different measures: physiological (Electrodermal activity),self-report (pre-post exposition), and richness of mentalimages elicited by the story(using Think-aloud technique after exposition). Results showed higher emotional impactof the arousal and 3D audio conditions with different patterns according to the age of theparticipants and distinctive types of interaction when both variables were combined.
