The Effect Of Intensive Auditory Cues On Flight Passengers’ Safe Behaviors, Tianhua Li
The Effect Of Intensive Auditory Cues On Flight Passengers’ Safe Behaviors, Tianhua Li
Theses and Dissertations
When passengers do not follow in-flight announcements, injuries can occur. It is critical to draw passengers’ attention and help them be aware of the importance of the instructions provided during in-flight announcements. Passengers’ attention can be improved by providing intensive auditory cues before announcements. The auditory cues with intensive acoustic parameters increase the hearers’ perceived level of urgency, and then, they are more likely to perform safer behaviors. Also, when the intensity level increases to an intermediate level, the stimulated persons should have better performance. However, when it increases excessively, their performance may be impaired. The study examined the effect …
