The Effectiveness of Improving Flight Passengers’ Safety Behaviors by Modifying Auditory Cues

Abstract

The purpose of the study was to examine the effect of the intensive auditory cues on passengers’ performance and annoyance. It is critical to draw flight passengers’ attention and help them be aware of the importance of safety instructions. A total of 46 simulations were conducted to collect participants’ performance and annoyance when hearing auditory cues. The findings demonstrated that passengers performed significantly better when hearing the intensive auditory cues with moderately high perceived urgency levels (PULs), whereas a low or an exceedingly high PUL of auditory cues impaired their performance. Participants also reported significantly higher annoyance with more intensive auditory cues. The current study suggested that the manipulation of PULs of auditory cues could improve passengers’ safety.
