What the paper says

ObjectiveTo assess the efficiency of rough auditory alarms in capturing attention during a piloting-like task under high mental workload that may induce inattentional deafness.BackgroundUnder high mental workload and stress, pilots may experience inattentional deafness, leading them to miss critical auditory warnings. This results from early inhibition of the primary auditory cortex by prefrontal areas, shifting auditory processing oscillations from gamma to alpha frequencies. Recent studies suggest that roughness-an auditory perceptual feature of natural alarm signals generated by amplitude-modulated sounds in the 30-150 Hz range-could attract attention at early perceptual stages. Auditory roughness could sustain alarm detection under cognitive load.MethodTwenty-seven participants underwent a demanding dual-task protocol. They simultaneously performed the Multi-Attribute Task Battery and an auditory oddball task including rough and non-rough targets. Participants also provided subjective ratings of the target sounds and of their perceived workload during the task.ResultsRough targets were detected more efficiently with higher hit rates and no cost to false alarm rate, reaction time, or primary task performance. Accordingly, participants rated rough alarms as more urgent, unpleasant, and salient. Overall workload was unchanged, but frustration and mental demand were lower and performance higher in the rough condition.ConclusionThis study provides promising evidence that rough auditory alarms enhance detection and help prevent inattentional deafness without degrading primary-task performance. Consistent with an effective alarm profile, roughness increased salience and perceived urgency.ApplicationIntegrating rough auditory warnings into cockpits could enhance alarm detection in cognitively demanding situations, improving safety.
