Auditory Progress Bars: The effects of Feedback, Endpoint and Free Response on Estimations of Time Remaining Academic Article uri icon


  • Auditory Progress Bars (APB) are non-speech auditory displays that indicate the status and progress of ongoing tasks. In on-hold telephone settings they may provide the caller with a means of estimating when their call will be answered. Here, participants used three distinct APBs to make estimations of the time remaining during a simulated on-hold wait. The benefits of feedback and hearing the APB’s endpoint on estimating time remaining were examined. Evidence is found that the accuracy of estimations differs by APB type and that feedback on initial estimations increases accuracy on later estimations. Knowing the APBs endpoint does not appear to increase the accuracy of estimating the time remaining in fixed intervals.
