Obtaining Objective Measurements Of Reaction Times To Auditory Alarms, Andrew George Neubauer

Theses and Dissertations

Several pulse parameters that were believed to affect response time to auditory alarms were investigated in a factorial experiment. 18 subjects, (14 male, 4 female), participated in an experiment where the effects of inter-pulse interval (125, 250, and 500 milliseconds) and pulse format (sine, sawtooth, and square waves) on both selfreported ratings of workload and reaction time to alarms (auditory and visual) were explored. The results show that alarms with a shorter inter-pulse interval produced the fastest reaction times. Subjective preferences were rated as equal. Accuracy was equal across groups as measured by amount of errors in responding to auditory …
