Measuring response times to auditory stimuli during an audiometry

This paper provides a methodology for the measure of the patient's reaction times to auditory stimuli during the performance of an audiometry. An audiometry is the standard way of analyzing the hearing of a patient in order to diagnose hearing loss. From a video sequence recorded during this test, the method will be able to detect the instants when the expert is sending the auditory stimulus and when the patient responds consciously to it by raising his hand, being able, this way, to measure its reaction time. The proposed method was tested on several video sequences from different individuals yielding highly accurate results. The possibility of quantitative measure the reaction times will allow the experts to conduct several studies and to further complete the evaluation of their patients.
