• A sound-generating otoscope was compared with standard audiometric testing. Subjects of different ages and with different auditory pathologies were examined. The sound-generating otoscope was found to agree 92.4% of the time. Errors occurred more often with subjects having normal hearing. No single frequency delivered by the otoscope produced a significantly higher error rate than had been reported by other investigators. The otoscope can also be used to detect collapse of the external auditory meatus that might occur during regular audiometric testing.
