Sage Journals: Discover world-class research

Abstract

Modern vehicles can present an ever-changing plethora of information, making it of the utmost importance that signals are evaluated efficiently in the early stages of design. The current study investigates the relationship between traditional methods of physchophysical scaling and newer methods of sorting or categorization. Participants sorted a sample of sounds into “Alarms”, “Status Notifications” and “Social Notifications”. Following the sorting task, participants were asked to rate each individual sound (using a 1-100 scale) on urgency, annoyance and acceptability. Results indicate extremely high correlations between alarm categorization and urgency level where sounds categorized as alarms by more participants were also rated as more urgent by all participants.
