Abstract

A research was initiated to determine if the psychoacoustic parameters of the non-verbal auditory alarms in the CH146 Griffon helicopter convey the appropriate level of danger. Ratings and rankings of the perceived urgency of these alarms were measured. Five non-verbal auditory alarms presently used in the CH146 Griffon helicopeter were considered. Analysis of the data revealed that the five tested alarms have different levels of encoded urgency, but these are poorly mapped to the urgency levels of the triggering situations.
